They add weight to the bike

Cycle wings do make the bike heavier to some extent, but their weight is insignificant.

For bikes that are used for XC or urban use, the extra grams from the fenders does not affect dynamics.

It is advisable to take care of such trifles if you are a professional racer. Every fraction of a second counts there.

But racing bikes are already devoid of fenders. Therefore, this argument does not matter for fans of ordinary pokatushki. What’s more, there are now carbon fenders on sale that weigh very little.

Does your bike need this kind of protection??

Fenders are installed not only to protect clothing from dirt, but also to protect components from excessive clogging.

Many mechanics and advanced riders oppose the installation of mudguards on sports bikes. Despite the fact that they will to some extent protect the rider from dirt on the back, this is still an extra knot, which means extra weight and additional problems with maintenance. Therefore, the decision to install the mudguards for the bike will be up to you.

Road bike mudguard

This is where lightness and aerodynamics are important, so aerodynamic options are quite appropriate, such as those on the car pictured below, namely the Crud RoadRacer Mk2.

These plastic fenders are very lightweight, they resist the pressure of dirt well and are almost invisible. Their cost is about 30 euros.

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 does not require removing the wheel for mounting. Also, almost all modern bogies have adjustable bows for greater versatility. Therefore, full-size bicycle fenders 26” may be suitable for 28” wheels.

  • Pass it down between the rear stays until it rests against the bracket on the bridge on the frame.
  • If there is a thread in it, 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.

From wooden profiles

Wooden fenders for a bicycle are a real gimmick that will take your breath away from passers-by, and your fellow transport will definitely want to make them the same. To make these wings, you need to have two wood profiles. For the front wheel, the wing length will not exceed one meter, and for the rear wheel, a one and a half meter wing is required. A workpiece thickness of 1 cm is ideal. A thicker profile will be inconvenient to work with, and a thin wing will not be reliable enough. Thin fibers located along the length of the workpiece are another mandatory requirement for wood, which will be used in further work.

They are lightweight, made of metal-plastic. Sometimes they are treated with a special water-repellent compound. Fix them to the frame. Advantages. increase the maneuverability of the bike. Disadvantages. high cost.

DIY bicycle wings

A bicycle is, although not such a complex form of transport as a car, its design still consists of a number of essential elements. Their absence, improper work or poor condition can cause a number of inconveniences to the user and even harm the transport. One of these elements is the wings, which you do not have to buy, you can make them yourself. As a result, you can not only save money, but also make your bike original, with an element of exclusivity.

Homemade fenders make the bike original and exclusive

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 install both bogies, we need a 4a hexagon and / or a screwdriver (depending on the type of wings), for old models. a 10 mm open-end wrench 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.
  • We put a rubber gasket in the clamp and tighten it on 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 tires no wider than 1.95”, but there are also models for mountain bikes.

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 lugs. 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.

Sports wings

Sports fenders are usually made of plastic and have a maximum of two attachment points. Mounting the mudguards on a bike can be done at home and even in the field. The types of rear bog attachment can be as follows:

  • Seatpost clamp. It can be produced both with a plastic adapter and with a cloth tape, which is more versatile, but may begin to slide out over time. An improperly fixed and adjusted wing will constantly fall onto the wheel. Installation requires a hex wrench / screwdriver.
  • The saddle clamp is not a very popular but cheap type of mount that is less and less common. Has a regular bracket with two eccentric ears. Clamped by it, no additional tools are required.

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.


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. 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:

  • wheel size;
  • tire width;
  • frame type.

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.

  • Using the eccentric seat clamp.
  • On the stem with a spacer nut.
  • On a gorilla or a fork and arc crown. For rigid forks only.
  • Fork legs with straps.

Homemade bicycle fenders (shields)

Bicycle fenders (fenders) are a rather troublesome and very necessary part. You can be content with steel wings. but their disadvantages are obvious: a significant mass and coating that does not meet the needs of cyclists (nickel-plated shields are too expensive, and painted ones are not resistant to scratches and dirt). Plastic fenders are not often found in everyday life. At one time the Kharkov Bicycle Plant produced polished aluminum shields. They were very attractive in appearance, but quickly disappeared from the stage due to corrosion in the attachment points: the steel screw and aluminum formed a rather active galvanic pair. German firms did not cope with corrosion either. Kharkiv residents tried bicycle fenders from thicker aluminum billets, but cracks formed in them from vibration.

Duralumin fenders made of a strip of 0.8 mm thickness are very operationally reliable. Dural with a steel screw, in our opinion, form a less active galvanic pair, and is held quite firmly. Thin-walled, the wings are practically weightless, so that cracks do not form in them either from vibration or as a result of shock in accidents. After any deformations, pliers and a hammer are enough to return the bike fenders to working condition, and when they return home with a punch, they can easily return to their original shape. True, there was a case when a fierce dog in Mongolia gnawed off a thin shield right up to the support. But this characterizes not so much the visor as the dog, which must not have liked the leather mudguard on the visor. But a mudguard is necessary, because it doubles the life of the chain. The advantage of the offered wings is that you yourself make them the desired profile and length.

A very suitable material for such wings is decorative profiled duralumin strips used for cladding the interior walls of public buildings. It is easy to cut out blanks of the required width and length from them. But good fenders for a bicycle are obtained from ordinary thin sheet duralumin. To give the workpiece the desired shape, you will need a locksmith’s hammer with a spherically turned striker and a wooden block with chisel grooves of various depths selected in it for the required wing profile of a bicycle. A little patience and your strip under the blows of the hammer will turn into a wing arch of the desired profile. The outer surface of the wing-flap after such a punch slightly resembles the pimpled skin of a toad. Work on it with your personal file and it will even become attractive. And after installing the fenders on the bike, you can also add moldings from a narrow strip of insulating tape of a suitable color.
