How to install fenders on a bike video instruction

  • The front fender is attached first (due to the maximum simplicity of this operation and additional self-confidence). The fender is brought up to the wheel and attached to the gorilla front fork with a screw and nut. Although the operation is simple, it is still worth taking it seriously, since overtightening the nut can easily damage the new wing (it can burst in the place of the overtightened nut), and vice versa, without tightening the nut properly, the wing will dangle and, as a result, dirt from under the wheels will fly right in the face
  • The rear wing will be a little more difficult to install, however, you do not need a higher technical education for this. Technologically, the rear wing can be attached in two ways: using a seatpost or attaching to a seatpost. Therefore, the first step is to determine what type of attachment in this particular case
  • If the fastening is carried out on the pin under the saddle, then first unscrew the pin itself with a screwdriver and remove the seat itself. Then the rear fender mount is threaded. The seat is placed on top and the screw is well tightened. The wing is securely fastened
  • If the wing is attached via a seatpost, then you need to unscrew the seatpost attachment with a screwdriver and slide it out. Now the rear wing is brought to the fastener until the fastening grooves and the grooves in the wing coincide. That’s it, you can screw on the seatpost. The wing is in place.

Good bike fenders start at 30 and up; cheap bloodworms don’t keep dirt out. Full-size fenders, do not fit on mountain bikes. But what if you have a mountain bike, it is many years old, but there is a need to put on the fenders, but so that their cost is not half the residual value of the bike itself? There is only one answer. to do it yourself using improvised means. At one time I made a set of 4 five-liter canisters of Tosola FELIX using tear-off rivets and plastic cable ties, there are other options. Google and you will find a lot of similar

All summer I drove without wings, I didn’t even think to buy them, but it was enough to drive once after the rain and ……. had to splurge on 24.

For or against installing fenders

If you are not an athlete and not a complete fan of the bike mount, then the installation of the wings is a must. Bicycle mudguards are determined by the type of bike and its purpose. Advantages of installing fenders:

  • It protects you and your bike parts from splashes and dirt;
  • Correctly fitted fenders improve the appearance of the bike and even increase its safety on the road;
  • The period between preventive maintenance and mountain bike adjustments increases;
  • The bike breaks down less, fails and washes less often.
    • The fenders also break, both when driving, and when parking and transporting;
    • Fenders can be difficult to store and transport.

    True, some of these difficulties can be eliminated by installing quick-detachable wings.

    Bicycle mudguards can be divided into two classes:

    • stationary;
    • quick-detachable.

    For mountain bikes, quick release mudguards are recommended. In principle, for a bike with two suspensions, this is the optimal solution. Almost all budget fenders are made of plastic, which practically does not affect the weight of the bike.

    Based on the above features, you can stop at the choice of suitable wings.

    How to attach fenders to a bike

    It is easy to guess that “standard” and “ordinary” wings do not exist in nature. They all differ in several ways.

    By diameter and width of the tire

    By bike mounts

    Bicycle mudguards without frame fasteners

    Full-size by material of manufacture

    Selection of wings by mounting method

    Exotic and homemade wing options

    Selection of fenders by tire diameter and width

    However, the wings do not differ in diameter by the same diameter. Look at the width of the fender so that it can completely cover your tire. This is especially true of mountain bikes, where the tires can be very wide, and even more so for fat bikes.

    Selection of fenders for mounting on a bicycle

    Once you’ve decided on your diameter and width, look at your frame and fork. Are there any holes for attaching the wing? On the fork, they should be on the gorilla (the bridge connecting the 2 parts of the fork) and at the bottom where the wheel is attached. On the frame, the holes (or “ears”) should also be near the place where the wheel is attached to the frame, in the lintel connecting the upper frame stays, as well as at the bottom on the lintel connecting the lower frame stays.

    If there are holes, then feel free to take a set of full wings. this will be the most practical option. The most that can get dirty is your shoes. Although this can be prevented by installing a mudguard (it can be included in the kit). Don’t worry about the appearance of your bike, even if you have a mountain bike. The not-so-cool appearance of a wing bike is easily compensated for by your neat appearance, regardless of the amount of water and dirt in your path.

    Bicycle mudguards without frame fasteners

    If you have a mountain full suspension or a hardtail without frame fasteners, then we have bad news for you. It will not be possible to completely protect against dirt and water due to the lack of the necessary fasteners for installing full wings. But quick-detachable wings can save you from total washing.

    With such wings, clothes below the waist will still be dirty, but if you went to a meeting with a girl, you can hide behind a bush and give her flowers from there. After all, from the waist up, you will look impressively good.

    In general, of course, on mountain bikes, fenders are not the most practical accessory and rarely provide complete protection. This does not apply to city bikes, folding bicycles and cruisers. There, the wings are a necessary element, without which it is impossible to imagine such bicycles, because they are equipped with wings normally from the factory. True, the wings offered by the manufacturer may not always suit you. After all, even full-size wings have significant differences, primarily in terms of material.

    Differences between full-size wings by material of manufacture

    Perhaps the most impractical option. Their only plus is that they are cheap. Everything else is a minus. They are heavy, making the bike significantly heavier. When shaking, they are very unreliable. the mount in the form of a corner strives to fall off the wing and often does it successfully. When driving, they create annoying noise, constantly blurt out, require frequent tightening of connections.

    Aluminum. Lighter than metal, but are very rare for the above reasons, and are much more expensive.

    Plastic. Also a rather rare option. They are much lighter than metal, inexpensive, but also not very reliable.

    Most popular, reliable and lightweight. Due to the thin metal base and plastic surfaces, they have high strength, they crack much less from many irregularities, and are quite elastic.

    The rest of the wings differ in the way they are fastened.

    The front fender is attached to the fork rod from below. The plastic sleeve is inserted inside, and thanks to the spacer mechanism, it is firmly fixed there. The rear wing is attached to the seatpost with a high-strength fabric clamp. Both wings can be removed in 5 seconds, which is why they got their definition.

    The front fender is screwed onto the gorilla forks. The rear is attached either only to the bridge between the upper frame stays, or it can have an additional hook to the seat tube of the frame.

    Exotic and homemade wing options

    Such wings can only protect a small part of the body, but they have a place to be.

    The shield on the frame will take away some of the dirt sent to you above the waist.

    The guard on the fork will take away some of the dirt intended to get on your face, and also protect the working surface of the fork from heavy wear.

    The spacer between the gorilla and the crown of the fork is also designed to keep your face clean.

    Saddle guard keeps your butt dry and clean.

    Most of the exotic “wings” can be made by hand.

    An excellent video about wings with your own hands.

    Whether wings are needed on a bicycle or not. everyone decides for himself. For example, a bicycle without wings is not interesting to me. Washing all my clothes after every cycling trip is not for me.

    I was interested in the last picture. Usually glossy wings like these break from a slight bend, but here someone bends the wing in half, and it does not break. I took the risk of doing this with my wing. It bent in the same way as in the picture, and unbent, while at the place of the bend there are not even traces left! So the quality of these fenders is pretty good.

    There are different types of rack attachment. In the photo. metal. My wings are plastic. They allow you to slightly adjust the length of the strut within 2 cm and supposedly separate themselves in problematic cases (apparently, if something gets between the wheel and the wing or struts).

    Attaching the fenders to the frame.

    Fixing problems started from the very beginning.

    Abandoned furniture was found at a local dump. There were aluminum corners bolted to chipboard panels. I unscrewed them, they are very light, their weight is practically not felt on the palm (much lighter than steel products). From one corner of the angle grinder, I made four adapters, drilling two holes in each in the right places:

    An important point. Although the axle of the wheel is smaller, a large hole was drilled so that the spring in it could move freely, otherwise it would be bullshit when installing the wheel. The shape of the adapter at the large hole should be such that from the side where the seat for the nut is not flat, the adapter can lie flat (parallel to the wheel) and not bulge to the side. A small hole is drilled to fit the diameter of the bolt handy for attaching the strut hinge to the adapter. Sawed off the bolts to the minimum required size so as not to interfere with the movement of the chain and cassette, used washers on both sides.

    The bike in the photos is turned upside down as the photos were taken while the fenders were being mounted.

    Since the loop is displaced from the center of the wheel by a few centimeters, the racks will have to be filed a few centimeters, one more, the other less.

    Plastic fasteners are screwed to the wing with complete screws, and steel struts are tightened by hand with a plastic nut. Adequate clearance between fender and tire.

    But the mount of the struts is initially located quite close to the wheel (about 1 cm). On wide tires, this can be a serious problem. So, Rapid Rob 2.25 lies almost close to these plastic mounts. On hummocks they will probably scratch with protruding “cubes”. When mounting the front wing, I found a simple solution (read below), with 2.0 everything became normal, but for 2.25 I would still not recommend buying these wings, or you will have to make homemade strut mounts (more widely spaced on the outer side of the wing).

    In addition to the twin steel struts, the rear wing has two more mounts. One. at the height of the trunk through the supplied plastic half-coupler. There is an unthreaded hole on the frame in this place, so the bolt and nut for this fastening must be selected by yourself. The other. at the very bottom. the hole on the wing is aligned with the hole in the frame and tightened with a bolt that is not included in the kit. The frame has already been threaded. There were no problems with the fastening itself in these places, but the fender squeezed the front derailleur, and it did not switch. I had to tinker to move the wing away from the derailleur closer to the wheel. In my case, a plastic spacer and a few washers between the wing and frame helped.

    As for the front wing. The top mount attaches to the hole in the gorilla. Honestly, when buying a bike, I was looking for one that has this hole, since many forks now do not have such a hole, and there you have to tinker with another homemade mount. But there are no holes for attaching the wing struts on my fork. The original idea was the same. to make adapters from the wheel axle. There, too, a non-flat seat for the nut, so it had to be filled with additional washers of the appropriate thickness. To be honest, I don’t really like the fact that something is hung on the wheel axle. The main disadvantage of such a fastening is that the wheel cannot be removed without twisting the nut and without removing everything that is on it from the axle, while small centering springs can be easily lost, especially if the wheel is removed in the field. But on the rear wheel so far I do not see alternatives, and on the front wheel I will try to make clamps for the fork in order to free the axle from foreign inserts. Maybe clamps are less aesthetically pleasing, but more “correct”? But so far I haven’t found beautiful plastic clamps, and I don’t want to make a tractor out of a bicycle by molding heavy steel water clamps onto it, so for now I’m driving with my aluminum adapters:

    The problem of the closeness of the wing-pillar attachment to the tire on the front wheel was more noticeable than on the rear. On the front fender there is not a double strut, but a single strut, so that at the slightest vibration, the wing began to “play” on the sides, and these plastic pieces hit the side teeth of the tire. Neither one nor the other benefit from this, of course. The only thing I came up with was bent the post in the place where it fits into the plastic fasteners, as shown in the photo. After that, the distance between the tire and the strut increased, the wing was fixed more rigidly, and nothing clings to anything. It turned out quite practical, so I also bent the struts on the rear wheel, as far as possible from the wheel.

    At first it seemed to me that the front fender was not low enough to protect the feet from dirt. In practice, no problems were noticed. When driving through puddles, feet remain clean. As if by the will of fate, after a few weeks I found a rubber bike mudguard (branded) rolled up in the sand on a forest road, which fit perfectly into my wing, but since I often have to moose in the forest, drag my bike through fallen trees, I decided not to put it down for now. because it is during forest losism that you understand why the wing ends exactly where it ends. If it were a little lower, it would cling to everything.

    For comparison, Schwalbe Hurricane Performance 2.0 fender and tire width:

    Well, to complete the review, a photo with wings. I can’t help but notice that the thin steel struts still do not provide rigidity, and the wings are rather wobbly. They haven’t touched the wheels yet, but it’s still unpleasant. Ideally, you should strive to arrange the wings so that these racks are as short as possible, but, alas, this does not always work out. You can click on the photo to see a larger image.

    Real world tests.

    Of course, I didn’t go into the mud on purpose, but the circumstances were such that I had to overcome several flooded areas, and I decided to take a photo for this article at the same time. I was quite pleased with the result. I drove out of the viscous mud absolutely clean, I didn’t even get my shoes dirty. Schwalbe Hurricane Performance, on the other hand, barely coped with the task. My feeling was that about 80% of the forces spent on pedaling was wasted, that is, the wheels just spun in place, barely maintaining movement. If it weren’t for the fenders, the rear wheel would definitely spit dirt all over my back. It’s amazing how I got out of the stream shown in the fourth photo at all. The exit from it was viscous and very slippery, the wheels were strongly sucked in, when they rotated, they were spinning in vain. If the swamp were a couple of meters longer, I would have to dismount directly into this mud. However, I will not completely criticize Hurricane. Firstly, they are not mud, but road, and the fact that they can pull out of a quick slippery swamp with their few teeth located only on the side is, as it were, even a plus in comparison with the classic road tire, which is generally useless for such places. Secondly, last year I had similar problems on the toothy Rapid Rob in these places. they also slipped noticeably, only less. As for the wings, they pay off. The fenders do not prevent dirty wheels from spinning, but they keep both the rider and the bike clean. The only thing I don’t like specifically about these fenders is the insufficient stiffness of the steel struts. Because of them, the front wing vibrates from side to side on irregularities, sometimes creating strange sounds such as bouncing.

    Application. Fastening the front fender with clamps.

    Supplement March 6, 2018.

    The fenders are still on the bike. I did not install the clamps, I left them as they were originally assembled. In general, I am satisfied with the wings, but I want to note one feature. Pine cones. If you drive on a road covered with cones, they are somehow tightened between the wheel and the wing, and the very protection that I wrote about at the beginning of the article is triggered. The wing is detached from the struts using a plastic connector. According to the manufacturer’s idea, this connector is disconnected and then snapped back with his hands, and in fact, this is usually the case, but, unfortunately, during the season I have already broken two such connectors with the help of cones. there the thin tendrils of the clip break off and they simply stop fixing. The wing begins to fly out of the retainer on each bump, rattles and interferes with movement, so this situation is very annoying on a long journey. Of course, on my return home, I just filled all these connectors with superglue and they no longer come apart, but those who are not familiar with this problem should keep this in mind. After gluing all the quick-release clamps with superglue, I no longer had problems with bumps.

    How to install bike wings on a mountain bike with your own hands

    First, the rear fender mount was assembled. Watch the video.

    Next, I checked the assembly of the front fender. The two wing halves are fixed to the mounting platform. The platform, in turn, is easily attached and fixed on the bushing. The expandable sleeve is fixed in the column. The kit includes three bushing parts of different diameters. See the photo. The bushing part is clamped in the column with a screw, which is tightened with a hex wrench.

    Fastened the rear wing clamp to the saddle pipe. Adjustment of the wing position is carried out by turning the clamp, the angle of installation of the bracket and wing. The rotation of the bracket is fixed with thumbscrews, and the angle of rotation of the wing with a hexagon. When installing the wing, do not forget about the travel of the rear wheel on the shock absorber. Final fixation of thumbscrews requires considerable effort.

    Clamped the front fender mounting sleeve. I tried on the wing. Corrected the position of the wing by turning the sleeve. Installed the wing.

    The wings retain their shape on the go (watch the video), but they are also flexible enough, which is highly likely to save them from damage both from foreign objects on the go and during transportation or storage. The front fender can be removed almost instantly, and to remove the rear fender you need to unscrew one thumb screw.

    The question of how to install the fenders on a mountain bike was solved by me. In my case, with the exception of a “surprise”, it’s easy to do it yourself. I bought the wings here at this link But there is also a budget option, although I will not say anything about the delivery time. I did not check.

    Thank you for your attention and good luck.

    The first step is to take a careful look at the fork and frame of your bike. They must be provided with special holes to which the wings must be screwed. It happens that such holes are already occupied and reflectors are screwed into them, but this is not a problem. However, it also happens that the necessary holes are not provided at all. In this case, you have to fix the wing to a yoke or other devices.

    If there is a hole, but it is occupied by reflectors, first you need to unscrew them. Then, using a screwdriver and a wrench, the bike fender can be easily and easily mounted either to the front of the bike or to the rear. The fenders can also be fitted at the back and front. To install the fender above the front wheel, a special hole was provided in the bicycle fork. The bike fender is put on from above and a screw is inserted into the hole, and on the other side the screw is tightened with a nut. Next, you need to make sure that the wing is securely fastened, and that’s it, we have installed the front wing.

    Now we need to figure out how to put the fender on the bike over the rear wheel. There are two mounts here. You can install a fender under the trunk. To do this, you need to remove the trunk in place of its fasteners, insert the wing, then put on the trunk and screw the fasteners back. The second type does not require unscrewing anything. The fender is attached to a post under the seat. Having unscrewed the screw, the wing is put on the pin and everything is fixed. The main thing is not to forget about the elastic band, which should be included in the kit. With her, the wing will hold better.

    You can choose any kind of wings according to your wishes. They are all fixed equally easily. With their help, no puddles will spray you now. Hate to endure wheel splashes after rain, but don’t know how to put fenders on your bike? Read this article to show you how to mount the mudguard on your bike quickly and securely.

    What tools do you need to have?

    It’s hard to answer this seemingly simple question right off the bat. To do this, you need to look at the type of hardware used (in case we are dealing with bolted fasteners) or screw drives of clamps (for quick-release fasteners). This may require:

    • Medium flat or Phillips screwdriver
    • wrenches (6mm, 8mm, 10mm);
    • internal hexagons or squares (4mm, 6mm);
    • appropriate threaded hardware (screws, bolts, screws. look at the standard screw holes in the bicycle frame).

    As a rule, in such a simple matter, you can always get by with an “emergency” set of tools that is “carried” with a bicycle. If, of course, it is available.

    What bicycle fenders are there?

    Everyone should know such elementary and fundamental data. By the nature of the fastening, bicycle mud guards are:

    • with screw fastening in the frame (they are still unfairly called “stationary”). such protective wings are usually full-size (but there are also shortened versions). This type of bicycle wing is practiced on the vast majority of types of bicycles. These include classic road bikes, city bikes, tourist tourers, pleasure cruisers, sports bike hybrids and even road racing. Threaded holes for fastening “stationary” shields can also be found in mountain bike frames (MTB).
    • with quick-release attachment to frame pipes. this kind of mudguards are most often practiced on only one type of bicycle. sports mountain bikes, sometimes. on bicycle hybrids. But since these types of bicycles are incredibly popular among many categories of cyclists, such fenders are very popular and in demand.

    Reasons for raising the question

    How do I fit or attach a mudguard or mudguard to my bike? For an experienced cyclist, the question seems too simple, not worth the detailed explanation. But only experienced cyclists are not limited to cyclists. There are also beginners, inexperienced, ultimately technically illiterate cyclists. Accordingly, such a question has a right to exist. If an inexperienced cyclist types in an Internet search engine a query like “how to attach fenders, attach the fenders to a bicycle”, he should find there an exhaustive answer to it. We will help him with this.

    Fitting Full Size (Short) Bolt-on Bike Wings

    As a rule, full-size bicycle fenders equipped with additional side rods have three attachment points. one central, in the frame, two lateral. at the ends of the wheel axles or on the tubes of the rear stays. But there are also simplified (shortened) options, with only one bolt in the frame.

    To mount such a “three-point” full-size bike wing with side rods, you will need:

    • determine which flap is installed, front or rear (they differ slightly in size and fasteners);
    • place the guard over the corresponding wheel (front, rear) so that the side links are on opposite sides of the bicycle wheel;
    • align the hole in the wing with the corresponding threaded hole in the frame, screw the shield with threaded hardware (screw, bolt) to the bike frame;
    • unscrew the side nuts securing the wheel axles, put on the wheel axles the eyelets of the side links of the mudguard, put the nuts in place and tighten them until they stop. If the side rods of the shield are fastened with clamps to the feather tubes, then. hook these clamps onto the pipes and tighten the fasteners of the clamps.

    Installation of quick-detachable fenders on mountain MTV

    In this case, the technology for mounting the front and rear flaps is somewhat different.

    In order to install the front quick-release shield, it is necessary to insert its mount from below into the steering tube glass, and tighten (screw) the spacer screw to the stop. Then put the shield itself under the plug, insert it into the fastening groove, press it down until it clicks. that’s it, the shield is installed.

    The rear quick-release wing simply attaches its clamp to the seat tube. Further, the adjusting mechanism sets the required mud gap between the flap and the wheel protector. and that’s it, the installation is complete!

    How To Install A Rear Fender Fast On Any Bike

    For or against

    Bicycle fenders have both advantages and disadvantages, which are determined by the type of bike and its purpose. Among the positive aspects of this part on the wheels, it can be noted that:

    • This is good protection against dirt and splashes from under the wheels;
    • Correctly selected, they do not spoil the appearance of the equipment;
    • Some types are quickly attached and removed.

    Fans of sports bicycles often do without fenders, as they make the bike heavier, which is unacceptable for sports. For city driving, this detail can be very useful: it will protect the cyclist from getting dirt on his clothes. In order to understand whether the installation of this element is really necessary, you need to try everything on your own experience, as well as choose the right type of fenders on wheels. They can be:

    The first option is quite common and they are made of plastic. You need to attach them to the fork or frame using a bolt. Protection is not complete, which in some cases may be significant. Their weight is small and therefore they do not particularly affect the weight of the equipment.

    Quick-detachable short ones are also made of plastic, but they have mobility. They should be secured with a special clamp, which allows for quick installation and removal. Many cyclists use this type of fenders on wheels despite the fact that the level of protection is not very high. It is important to carry out the installation correctly, otherwise the part will be useless.

    Long stationary fenders for a bicycle are metal parts that are installed by attaching in three places to the fork, frame. The area of ​​protection against dirt flying from the wheels is quite large, but it is necessary to periodically clean the part itself. They are most suitable for road or road type bicycles.

    How to install fenders on a bike

    Maintenance: DIY bike fenders

    Bicycle. it is an environmentally friendly transport and driving is very popular. Owners of this technique must have some skills in maintenance and repair, because this will allow you to quickly and effectively find a way out in unforeseen situations, for example, glue the camera or put the wings on a bicycle. The latter option causes a lot of controversy among fans of two-wheeled vehicles. It all depends on individual preferences and it is worth familiarizing yourself with this topic in a little more detail.


    Mobile versions of this part are quite easy to install, but the process of fixing stationary ones requires especially close attention. Before starting work, the rim brakes must be disengaged so that the rear fender can be attached without problems. Then you remove the screw located under the seat and you need to put the element on the seatpost post. The front fender is easily bolted into place at the fork crown. It is important to calculate the force with which the bolts are tightened. If you tighten it too tightly, then the fasteners can be damaged and become unusable, in the opposite case. it will hang freely and interfere with driving.

    Most often, the option of installing one part is not chosen, it is more efficient to put a complete pair. This will provide the best protection against splashes and dirt. If you plan to install a roof rack, you must first install the rear wing. In the case of an already installed trunk, it must be removed.

    • Nuts;
    • Screws;
    • Screwdrivers;
    • Keys to fit.

    Now the question of how to install the fenders on a road or road bike has been resolved. It is not difficult to choose the appropriate option, because modern manufacturers produce a sufficient range of such devices. You can also make wings yourself, but this is a rather laborious process. Correct fit will ensure the functionality of the part and not render it useless, weighing down the bike.

    Fast (universal) installation option

    This method involves fixing the front wing with a strut. The protective element itself consists of two parts and is docked with a metal plate. The long part of the wing is worn on the bottom, the shorter part on the top. The workpiece is ready. Next, you need to prepare the fastener and install:

    • Includes screw, washer and two pieces of spacer. A washer is put on the screw, after which it is passed from the bottom of the metal plate.
    • The first part of the spacer is put on top of the screw without a nut, then the second part (with a nut) is slightly screwed on.
    • Now you need to look under the crown of the fork. There is a hole in which the spacer is inserted. After placing it, start tightening the screw with a screwdriver. Parts of the fastening element will begin to move apart, which will ensure that the wing is retained in the cavity. If the spacer is not wide enough, use the included pad. If it is absent, you can independently cut the rubber strip from the old camera.

    Next, let’s take a look at how to install a rear fender with a yoke on a bike:

      Place nuts inside the clamp, connect it to the wing attachment part, tighten the components with screws.

  • Take the wing and place the holder base on it. Fasten it with the screw and washer.
  • Install a threaded pin in the extension mount, dock it with the base screw. Tighten the connection tightly.
  • Loosen the retainer and remove the seat post. Put the clamp on it and press it down with the screws. You need to twist them one by one, pulling each one by several turns.
  • Join the workpiece to the clamp using the appropriate screw.
  • By loosening the individual fasteners, it will be possible to adjust the installed protection in height and angle of inclination. When riding over bumps, the wing may drop spontaneously. This drawback is present in some models, and it will be possible to completely eliminate its appearance only by installing a different design with additional “antennae”.

    Types of fenders for a bicycle

    There is no single classification of types of fenders for a bicycle. However, one of the main characteristics is length, or rather dimension. Full-size fit snugly to the wheel and provide the most effective protection against water splashes. Short ones are installed significantly higher above the wheel surface and are designed, first of all, to protect the rider from dirt.

    Good to know! The design of full-size models requires additional attachment points. They are realized due to the wire “antennae”, which are fixed on the axle of the wheel.

    The next difference is the fastening method. The front fender is installed by means of a spacer that fits into a hub under the crown of the fork. The second option is to mount with a plate and screws that are fixed to the hole in the gorilla of the plug. Make sure your bike has the hole you need before purchasing.

    Important! The rear fender is secured with a clamp that fits over the seatpost. The second option. the plate and the screw are threaded into a special hole, and the bracket is additionally installed on the seatpost. We will tell you more about the installation by each of these methods below.

    A detailed description of how to install fenders on a bike

    Not all bicycle models are equipped with fenders. However, after riding in the rain or mud, the owner of the bike begins to seriously think about their need. In the article below we will talk about the types of wings, their advantages and disadvantages, installation methods.

    Installing mudguards on a mountain bike

    The exact installation sequence will depend on the design. Typically, manufacturers provide visual instructions that can give you a general idea of ​​the location of elements and fasteners. In the material, we will talk about two installation methods: quick (using a sleeve and a clamp), and also more reliable (screwing the plate into special holes on the frame).

    Do you need fenders on a bike

    It is easy to guess that the main task, as well as the main advantage of the wings, is protection from water and dirt. After installing them, the owner of the bike will be relatively isolated from splashing from under the wheels. Nevertheless, some disadvantages should be taken into account:

    • Increase the total mass of the bike. This parameter will have a significant impact in the case of installing metal models, which are currently a rarity.
    • Decreased cross-country ability. When driving over irregularities, the applied shock absorption can cause the wheel to rub against the protective element. In addition, if the bike is equipped with rain fenders (minimum clearance with the wheel), then when passing through muddy areas, they will instantly clog. This will create unnecessary resistance and may cause a forced stop. In urban conditions, the problem will be irrelevant.
    • Changing the original bike design. The point is controversial and depends on the personal preferences of the owner.

    If the voiced minuses do not scare you, and you have decided whether you need fenders for a mountain bike, you can proceed with their selection and subsequent installation.

    Installation through special holes

    If the bike has holes above the rear and front wheels, then you can purchase fenders mounted on plates. Instructions on how to put the front fender on the bike:

    • Insert the plate into the splash guard.
    • Open brakes if V-brakes (rim) are installed.
    • Attach the wing with the plate to the hole in the gorilla forks. Thread the screw.
    • Adjust the height. rubber should not rub against plastic.
    • Tighten the fastener. If necessary, you can fix the nut with a wrench, and screw it in with a screwdriver.

    Note! Similar fenders are installed on city bicycles. Usually they have additional fasteners. wire antennae. They snap into place at the bottom of the fork. Before purchasing them, you should make sure that you have all the necessary holes on the frame.

    A rear wing of this type can consist of two parts and is also attached through a special hole:

    • The bracket is installed on the front frame, after which the front part of the protective element snaps into it.
    • V-brakes open if necessary.
    • Take the bracket, screw and nut. The screw is threaded into a special seat above the wheel. The bracket is put on the screw as tightly as possible.
    • The wing is threaded through the bracket. its edges should lie in the grooves. The procedure is simple and seems complicated only in words. Planting depth is selected according to personal preference.

    The instructions presented in this article will help you figure out how to attach the front and rear fenders to your bike. There are no universal recommendations regarding this procedure, however, the outlined sequence of actions will allow you to understand the general principle of installation and apply it on the purchased model. When choosing a wing, you should pay attention to its width so that it completely overlaps the tire. Length plays an important role. the longer it is, the less water and dirt will get on the rider.

    Installation principles

    Fitting the fenders to a bike is, in principle, simple. Even a beginner cyclist with a minimum set of tools can easily cope with this. It will be a little more difficult to find a high-quality model and determine the type of installation that will be suitable for a specific situation. The whole variety of fenders can be divided into two large groups: stationary and quick-detachable.

    Some installation features

    If the protective elements need to be installed on a bike with rim brakes, then they will need to be slightly loosened or, in general, turned off and only after that proceed with installation.

    In some cases, a reflector or corner reflector may be located at the point of attachment of a fixed wing. In this situation, there is nothing terrible and irreparable, moreover, the length of the bolt is sufficient for both of these elements to be fixed.

    Installing the front wing is most often reduced to performing the attachment at only one point. Designs that are equipped with a so-called mustache are not affected. For a wing on the rear wheel, two fasteners are usually intended: the element is attached to the frame with a bolt, and to the bottom of the seat tube it is attached with its lower part. Some manufacturers equip their products with special arc-shaped latches.

    If there is a trunk in the bicycle, the wing is installed under it, if the design of the bicycle, wing and the trunk itself allows this.

    Typically, the front wing is only attached at one point, while the rear has two mounts.

    You can remove vibration on the wing and eliminate displacement during intense rides with rubber bands, ties and other elements that will pull the wing to the trunk structure.

    Installation of stationary wings

    Accessories of this type are screwed onto the rear stays and the front fork. City bike owners can opt for larger models that cover half of the wheel. As a part of such accessories there is usually high-quality metal, and long “whiskers” made of wire are responsible for fixing them. They cling to the tips on the wheel axles.

    During installation, pay attention to the height of the wing. If it is located close to the wheel, the splash protection will be more effective. But in this case, one cannot hope for high cross-country ability, which will be well felt while moving on difficult tracks. Dirt will clog under the wings, and it will have to be cleaned up periodically.

    Stationary fenders are screw-mounted to the rear stays and front fork

    Installation diagram

    In most cases, the installation of protective elements is carried out according to the general scheme, which looks as follows:

    • We unfold the package with upgrade elements and a set of necessary fasteners.
    • We fix the rods on the protective elements.
    • We collect them.
    • When working with the front element, it is necessary to unscrew the white reflector and fix the first fixture under its bolt. Two clamps will have to be fitted onto separate bolts with large washers.
    • When working with the rear wing, it is necessary to bend the plate and secure it in four places. The fastening of the two clamps is carried out in the same way as described in the previous paragraph. For the third mount, you need a six-bolt. It must be strung on a tube and plate. The last fixture is at the bottom of the pipe on which the saddle is attached.
    • Fenders installed may require adjustment. Its meaning is to adjust the clamps and mountings in such a way that there is no friction between the wing and the wheel.
    • Now you can tighten the bolts to the maximum level.

    Bicycles Forward

    How to attach fenders to a Forward bike is a topical question for many owners of these solid bikes. To handle the front wheel, follow these instructions:

    • It is necessary to install and fasten the wing on the bracket using M5 × 10 bolts, not forgetting about the spacer plastic washers. A similar procedure applies to both wings.
    • The wing can be mounted in the hole in the fork stem. To do this, you need to install the M6 ​​× 40 bolt through the washer in the bracket.
    • The lower support sleeve is installed on the bolt, while a special protrusion, which is located on the sleeve, should be located in the slot on the bracket.
    • M6 nut is installed in a special hole in the upper support sleeve.
    • In turn, the upper support sleeve is installed on the lower one so that they are in contact with each other with their beveled surfaces.
    • Bolt M6 × 40 is tightened for threaded connection with the corresponding M6 nut.
    • The front fender should have special adapters with different diameters. It is necessary to select the adapter that will fit the stem bore.
    • The assembled protective element is installed with an adapter into the rod hole, and the M6 ​​× 40 bolt is tightened. The installation of the front fender on the Forward bike is now complete.
    • To install the rear wing, it is necessary to install an M6 nut in the lower bracket, which is placed on the knee and connects the unit with an M6 × 25 bolt with an intermediate washer. The bolt can be tightened.
    • Next, a clamp is installed on the other side of the knee. In the process of connection, it is necessary to use an M6 × 25 bolt, a washer and an M6 nut.
    • An M5 nut is installed in the mounting holes on the lower bracket, and then the wing is placed. M5 × 12 bolts and plastic washers are used to connect this assembly.
    • The M6 ​​nut is installed in the clamp bore. To connect this node, you need to take a bolt M6 × 25.
    • An adapter with a diameter that will fit the size of the seatpost is installed in the clamp.
    • The assembled wing can be mounted on the seat tube by tightening the fixing bolt.

    Bicycles that cannot be fitted with fenders

    There are very few such models. Basically, these are just track bikes, frames of the last century with a very abstruse design, as well as narrow-focus and special-purpose bikes. It also happens that you can install fenders on a bicycle, but it is not recommended to do so. For example, in such cases:

    • Your bike has a rear shock absorber. For this, the maximum carriage shield will fit.
    • Your bike belongs to some kind of sports discipline where you don’t need a bogie. This is usually BMX, trial, highway, street.
    • There is no attachment point or it is occupied by something else.

    In all other cases, you can install bogs.

    Decide on the size

    Bicycle mudguards are selected depending on:

    Installing Front and Rear Bicycle Fenders.

    Most of the fenders are universal, that is, they can be simultaneously installed on wheels 24/26 / 27.5 / 28/29. Retractable wings are also found in nature, but as practice shows, this design is not very successful. The wider the wheels, the wider the bog, and the wider the bog, the better the protection. The standard width is about 60 mm. Fatbikes are usually not protected.

    There are also several options for attaching fenders to a bicycle. Rear:

    • Seatpost / tube.
    • On a dedicated lintel on the frame and bow. Suitable only for frames that support this feature.
    • Using the eccentric seat clamp.
    • On the stem with a spacer nut.
    • On a gorilla or a crown of a fork and an arc. For rigid forks only.
    • Fork legs with straps.

    Installing the rear mudguard

    The rear fender is a little more difficult to fit on a bike. A full-length bogie at the end can be frame-mounted or have a quick-release seat tube clamp. The latter is more versatile and fits almost all bicycles, and for mounting it is not necessary to remove the wheel. Also, almost all modern bogies have adjustable bows for greater versatility. Therefore, full size 26 “bicycle fenders can fit 28” wheels.

    • Pass it down between the rear stays until it rests against the bracket on the bridge on the frame.
    • If it has a thread, just install the bolt, otherwise insert the through bolt, washer and install the nut.
    • As in the first case, screw the arcs to the frame.
    • Screw / snap the clamp onto the seat tube or screw the end to the frame.
    • Adjust the bogie in height relative to the frame and tighten all the bolts.
    • Put the wheel back in place and recheck the brakes if necessary.

    Done, you have installed both fenders and are now completely protected from dirt.

    Installation of a sports bog

    It should be understood that all bogs are different, so it will not work to tell how all models and types are mounted. To mount both bogies, we need a 4a hexagon and / or a screwdriver (depending on the type of fenders) for older models. open-end wrench 10 mm and 15 minutes of free time.

    The rear wing mounting process is as follows:

    • Cut off the label and plastic ties, if any.
    • We wipe the attachment point from dirt.
    • Unscrew the clamp bolts and disassemble it.
    • Place the rubber gasket in the clamp and tighten it over the seatpost. It is not necessary to tighten the bolts all the way, you may need to adjust the position a little.
    • Next, we attach the bog leaf itself.
    • Adjust the position and tighten all the bolts to the end.

    Mounting the front bogie with mounting in the fork rod:

    • Removing the front wheel.
    • We assemble the spacer adapter in accordance with the instructions, if it was not assembled earlier.
    • We connect the mounting hole and adapter with a bolt.
    • Insert the spacer plug into the stem hole and tighten it to the maximum, pre-aligning it perpendicular to the plug.
    • Putting the wheel back in place.

    Touring Bike Fenders

    Full-size bicycle fenders are plastic or metal arches that cover the wheel approximately halfway down the horizontal line. Can be attached with two or one arch. There are versatile models on the market that are height adjustable for maximum protection from dirt.

    These bicycle fenders cover at least a quarter of the wheel and are very good at keeping out dirt. Fits on touring and hybrid bikes with 1.95 ”tires, but there are also mountain bike models.

    Suppose your frame and fork allow for bog mounting. In this case, you will need a screwdriver and / or a 10 mm wrench. To fasten the arcs. an 8 key or a 4 hexagon. Attaching the front fender is very simple:

    • Lean the front fender against the hole in the crown of the fork, or on the gorilla for a shock absorber.
    • Insert the supplied mounting bolt, washer and nut. If there is a thread in the gorilla, then just attach the bolt.
    • As you can see, the arcs have almost fallen into place, and they only need to be tightened. All modern forks are threaded in the bow ears. So just screw on both arcs.
    • Adjust the height of the bog so that it is as low and close to the tire as possible, but does not hit it.
    • Tighten the bolts all the way.

    Choosing wings: types

    Mudguards, like other bicycle parts, have a huge number of varieties:

    • The most common are full size wings. The oldest type that appeared with the release of the first bicycles.
    • Sports. They are made of flexible plastic, which saves them until the mount bursts. Designed to fit mountain bikes with 24-29 ”wheels. High-quality models generally fulfill their function and look quite stylish.
    • There are sports bog guards to protect the frame from dirt. They are a small plastic shield (about 15-25 cm), which protects only the rod itself and the steering column from dirt. This type of bicycle mudguard is very popular with mountain bike enthusiasts and new hardtails that do not have any dedicated arc mounts on the forks. A similar bogger is also installed on the seat tube to protect the bottom bracket and shock absorber.
