How To Put The Rear Wheel On A Speed Bike

How to convert a mountain bike to a single speed bike

Hopefully my recent post, One Is Enough, has convinced some of you to try your hand at mountain biking alone. The good thing about singles riding is that you can do it cheaply by retrofitting a bike you already own for less than 30! You can spend a lot more, but the basic conversion will only allow you to ride in one gear and is ideal if you just want to try a solo sport. Converting an old bike to SS. Also a great way to breathe new life into it and finally get it out of the garage and hit the track again.

Riding my SS to help with the One Is Enough article. Brianw decided to convert his old 1991 Trek 830 to SS. We’ve only done a basic rework on his bike, and that’s what this article is about. Future updates are included at the end, however, if you want to make a full, bombproof conversion.

Yes, you can even convert a full suspension bike to an SS. You just need a special tensioner. I used a Yess ETR-V to transform my Anthem for my first acquaintance with SS. I liked it so much that I ended up creating a special SS 29er hardtail and ditching Anthem.

Additional Information. How to reinstall the front wheel

1. To the right the wheel back into the fork: If you have rim brakes, be careful not to dislodge the calipers when reinstalling the wheel. If you have disc brakes, place the rotor between the brake pads.

2. Tighten here: If you have a quick release here, fully install the wheel in the dropouts. Make sure the quick release is on the non-drive side of the bike, in line with the wheel. While holding the lever in place, tighten the nut on the opposite side and move the lever to the closed position. It should feel tight to the touch, but it shouldn’t be too difficult to close the lever. If you have Thru, here, match the hubs with the holes in the bottom of the fork. Look at which side of the fork there is a thread, and push it from the opposite side. Turn the lever clockwise to thread it into the fork. After tightening, move the lever to the closed position.

3. Flip the bike: If you have cantilever or rim brakes, make sure the brake cable is reconnected or tightened correctly.

4. Spin the wheel: When spinning the wheel, you make sure your brake pads are not rubbing against the rim or rotor. If your wheel isn’t spinning, it might be bent in the fork dropouts. Turn the bike over, Loosen here, push the wheel and tighten again here.

Helpful Hint: If you have hydraulic disc brakes, do not apply the front brake after you have removed the front wheel. The brake pads will move closer together and you will NOT be able to return the brake rotor between the pads. If your brake lever is accidentally compressed, the ideal shoe separation tool is a shoe separation tool. If you don’t have this tool, you can use a flat-blade screwdriver or credit card to insert a wedge between the two pads and gently separate them. Too much force can damage the pads. Also, make sure any tool you are using is clean and does NOT contaminate the brake pads. Change the wheel and press the brake lever several times to reset the pads.

Quick Connect or Through Here?

The quick release here has a 5mm rod with a cam lever on one side and a nut on the other, and its function is to allow you to remove the wheel from the bike without using a tool. The quick release here also allows you to remove the wheel instead of removing it. That will stay in the hub, all you have to do is move the lever to the open position and loosen the nut on the other side.

Some bicycle hubs (especially mountain bikes) require larger axles (12mm, 15mm or 20mm) called thru axles. These wasps also have a cam lever on one side of the hollow shaft and the other side is screwed into the fork. This system allows you to remove the wheel without using any tools, BUT you need to remove it from the hub to remove the wheel from the bike.

If you have a bike rack on your car roof that requires the front wheel to be removed, make sure you have the correct adapter for your bike’s axle!

Disc brakes

Bikes that use disc brakes on the hub need special attention. Wheel disc brakes (Dual Pivot, Linear Pull, Cantilever, Sidepull, etc.) generally do not apply significant axle pressure. Disc brake systems are fork-mounted and apply a load to the rotor, which is attached to the hub.

There is an external load on the hub axle, which tends to push out of the overlay on the frame. It is especially important to secure the pin properly in disc brake systems.

Required details

Spacer kit. Get one that includes different sizes of spacers to fine tune the position of the rear gear for a truly straight chain line. Some cheaper kits only come with two spacers. I do not recommend them.

Rear hub. If your hub has a steel hub casing (common on most low end bikes) a cheap stamped cog will do, but if your hub has an aluminum hub casing you should get a custom SS cog with a wider base to avoid the hub casing extruding.

Tensioner. It keeps the chain in good condition and tightens and prevents it from falling. There is a small chance that you will not need it, but very small. Take one. You can always pick it up if it turns out that you don’t need it.

Chain. Most stainless steel rear cogwheels do not fit 9 prong chains, so you will need a stainless steel chain or 8 gear chain. If you are remodeling an old bike, it may already have an 8 speed chain on it, so DO NOT hesitate to reuse this chain on your SS setup unless it is too worn out.

Some companies offer stainless steel conversion kits that include spacers, teeth and tensioner, which is easier and cheaper than buying the parts separately.

Brainw purchased Origin8 SS conversion kit that included multiple spacers, two gears and a tensioner.

A quick note on gearing: The gear ratio / combination you use depends on your skill level and where you live. Someone in Denver, Colorado probably needs lighter gear than someone in Savannah, Georgia. Ask in your area for recommendations.

Solid here

The rear frame pad in the solid axle can also have a gearshift mechanism that is bolted on. There must be a bolt and a nut that holds it. The wheel is mounted on a suspension. That should be located on the back of this bracket, with which the right side is moved forward. Tune the wheel and check the nuts.

How to remove the front wheel to place the bike on a rack or in a car

Whether you’re mountain biking on the Local Trails, packing your cruise bike for a beach trip, or taking your Road Bike with you for a family vacation, you may need to remove your front wheel to take the bike wherever you want. Removing a wheel from a bike will make it easier to fit in the rear of your car, and some bike racks require you to remove the front wheel before you can strap your bike to a rack. You will also need to know how to remove a wheel if you have a flat tire. See our on How to Remove and Fix a Bicycle Tire.

Quick release

The eccentric mechanism for fixing the axles of the wheels uses a hollow bushing equipped with a shaft, a lever, which works as a cam mechanism, and an adjusting nut. The cam creates tension on the shaft and pulls, and press the adjusting nut firmly against the lining on the frame. This tension holds the wheel securely to the frame.

The adjusting nut determines the amount of tension on the cam lever for securing the wheel axles and cam. Lubricate the cam mechanism if it is sticky or dry.

The eccentric mechanism for securing the axles of the wheels is equipped with two conical springs. The small end of the spring faces the axis and the large end faces outward. These springs make it easier to fit the wheel. If one or both springs are twisted or damaged, they can be removed. They don’t matter as long as the wheel is firmly attached to the bike.

The so-called “open cam” may require more tension. These levers have a cam mechanism and must be lubricated frequently.

How to put a wheel on a speed bike. When is it necessary

Like any vehicle, a bicycle must be inspected and repaired in a timely manner. One of the mandatory procedures is to separate one or all wheels from the frame. The reasons when dismantling is required may be:

Removing a wheel

It will be easier to work if you do it in a place where it is convenient to approach the bike from either side. Dismantling wheels from a bicycle with rim brakes is carried out as follows:

  • Release the brakes. Unclamp and bring the levers towards each other, then. lift the swing lock.
  • Loosen the chain. will spin the wheels as much as possible, installed on the smallest sprockets at the back and front.
  • If the tires have a large diameter or large tread. release air.
  • The “car” is turned over, set on a special stand or just on the floor. The main thing is that the emphasis on the steering wheel and seat is stable, and the bike does NOT fall over. However, if it is equipped with a hydraulic braking system, this position is highly undesirable, since there is a high probability that air will enter the brake line. Keep the bike upside down as little as possible.

How To Put The Rear Wheel On A Speed Bike

Loosen the brakes
loosen the chain
Unscrew the wheel

Loosen the chain before removing the rear wheel of the bicycle. To do this, you need to set the minimum gear ratio (asterisk). Further, the course of work depends on the type of attachment:

  • Nut. Install two keys on opposite sides of the wheel, holding one stationary. Twisting the second in the opposite direction clockwise. The nuts can be removed completely or only loosened to remove the wheel.
  • Eccentric. Loosen the fastening by lifting the lever upwards, from the reverse side. slightly Unscrew it, making a couple of turns against the clock hand. I took a rag in my hands so as not to get dirty, take the wheel a little to the side to remove it from the mount. The chain is removed last.

Before removing the front wheel, the eccentric clamp (located to the left of the hub) must be turned 180 °. On the right side of the sleeve, the nut is turned a couple of turns. It remains to release the front wheel from the bike by removing from the fork tip.

If the bike has disc brakes, then before removing the wheels, you need to take care that the discs do NOT accidentally close. Otherwise, you will have to spend a lot of time and effort on unclenching. To prevent this from happening, you need to insert an object (a piece of cardboard, folded paper) or a plastic plug (included in the kit) into the slot.

Nut mount
Eccentric

Take the survey

  • Significant damage or malfunction of the rim;
  • Damage to spokes, tires or tubes;
  • Repair of the bicycle sleeve;
  • Replacement of a wheel as a result of the complete dilapidation of the old one;
  • Rear sprocket system wear.

In addition to preventive maintenance and repair, dismantling may be required if the bike is in good working order. For example, when you need to transport to another place, and there are mounts for the car roof. Then it is more convenient to disassemble the vehicle into parts in order to transport it in the trunk or cabin. In such a situation, you should definitely know how to properly remove the rear wheel on a bike at speeds.

Dismantling and assembly are simple procedures, but only if you know the sequence of operations. In addition, an independent department has a number of other advantages: there is no need to spend money on workshop services, you can do everything anywhere at a convenient time. Plus. improve service skills at the same time.

If for experienced cyclists this is a matter of a couple of minutes, beginners or riders with little experience will have to spend more energy to master the wisdom of how to remove the rear or front wheel from a high-speed bike, and then put the elements back.

Removing and installing a bicycle wheel. Removing the front wheel from the fork

Removing a wheel is the simplest maintenance procedure for your bike. This is done very simply:

  • Bicycle turned upside down.
  • Opening the rim brake, remove the caliper from the disc.
  • Loosen the fasteners from the fork dropouts.
  • Remove the wheels from the mountings.

On dropouts, the mount is nut and eccentric. In the first case, you will need two 15 mm wrenches. with one we hold the nut, with the second we carefully twist it on the opposite side. With the eccentric, everything is easier. loosen the retaining nut and fold the clamping lever.

When to remove the front wheel:

  • Replacement of tubes / tires;
  • Needle tightening / loosening;
  • Bulkhead bushing;
  • Rim painting.

Installing the front wheel on the fork is done in reverse order.

Removing the rear wheel

Similar to the front, but slightly different due to the rear derailleur.

1. Disconnect the brake cable.

2. Set the reverse gear so that the chain is on the smallest sprocket.

3. Loosen the eccentric handle and carefully remove the wheel.

Solid here

The rear frame pad in the solid axle can also have a gearshift mechanism that is bolted on. There must be a bolt and a nut that holds it. The wheel is mounted on a suspension. That should be located on the back of this bracket, with which the right side is moved forward. Tune the wheel and check the nuts.

How to remake Singlespeed

Let’s try to convert a regular bike to a high-speed one with a single shifting system. For this you will need:

  • Singlespeed;
  • Non-brake bushing;
  • V-brakes or pliers, front and rear;
  • Rear cassette 6 stars;
  • Two speed bike chains;
  • Switch;
  • Shifter;
  • Switch cable;
  • Clamps.

Tools and working devices:

  • Spanners;
  • Chain squeezing;
  • Cassette remover;
  • Grinder.

At the very first stage, you should choose the type of brakes, which we will then install on the bike. We look at the feathers and the fork. if they have seats for the brakes (they are not provided on classic frames), then purchasing pliers. If there are sockets, we take v-brake. Another, more complicated, option is to place a similar fork under the vectors, and put a tick back. In this case, you will have to remove and change the plug.

How to convert a single speed bike into a multi speed bike. Step by step instructions:

1. Remove the rear wheel with a wrench and disassemble it.

2. Open and remove the circuit. you will NOT need it anymore.

3. Make one of the two chains, with 128 links for a 6-speed cassette. To unclamp additional links to a standard chain and connect them, you will need a squeeze.

4. Next, you need to put a non-brake hub in the rear wheel. The work is divided into 3 stages: dismantling a conventional hub, re-spacing the wheel and installing a new hub. It is quite difficult to do the repositioning, therefore it is better to entrust this work to the master. A simple option is to purchase a ready-made wheel with a 6-star cassette.

5. If you install the sprockets yourself, you will need a cassette remover.

6. Putting the rear wheel on the stays of a standard frame will NOT work. the speed hubs are wider. To do this, you will need to open the feathers by 2-3 cm.This is easiest to do on the machine.

7. The next step is to install the derailer. the rear derailleur. You should choose a device with a mount on here, because. No special attachment for classic frames.

8. Apply front brake. standard procedure.

9. The front sprocket on single speed bikes has thicker teeth so the speed chain will not fit. We remove the star paired with a connecting rod, grind the teeth on a milling machine.

10. Assemble the bike: place the wheel on the feather dropouts, the chainring on the carriage and clamp the chain.

11.When the rear wheel is in place, apply the rear Caliper brake.

12. Installing the rear shifter for the switch on the right side of the steering wheel.

13. Connect the shifter and the switch, fasten the cable to the upper tube of the frame with clamps.

14. Finally, check and adjust the switch.

By changing the configuration of the transmission and installing a new braking system, a simple bike can be turned into a high-speed.

What are high-speed bicycles

By the type of transmission, bicycles with speeds can be divided into three types:

  • Dual Shifting: Mountain, Road and Hybrid bikes;
  • With single gear system. high-speed road models;
  • Planetary Velocity Models.

The dual gearshift system has two star systems. at the front in the bottom bracket and at the rear hub. By shifting the chain along the front and rear sprockets, the corresponding switches are responsible. front and rear. Standard systems:

  • 3 x 7;
  • 3 x 8;
  • 3 x 9.

There are several rear sprockets for one chainring: a large chainring in the front is combined with small rear ones, and vice versa. Average values, for example, 2 x 5 are commensurate with the gear ratio of a single speed. The switches are controlled by the shifter located on the steering wheel: on the left. in front of it, on the right. the rear switch.

A single gearshift system includes only the rear cassette, one derailleur and, accordingly, one shifter. In front, the chain only runs along one leading star, like on a single speed.

City bicycles with speeds make it possible to move more comfortably on roads with inclines, have a more developed braking system. front and rear v-brake against the drum rear brake of a conventional bike.

It is worth noting that in the city high-speed roadways run better than mountain ones: there are high gears, large wheels, the geometry is sharpened for movement on smooth roads.

The planetary gearshift system is located in the rear wheel hub. The planetary hub transmission combines the characteristics of Single Shift and Single Speed:

  • Rear switch shifter;
  • One front and one rear sprocket;
  • The chain is short, runs straight.

Gear shifting is carried out while coasting, in contrast to the classic system, where the chain is thrown over the stars when pedaling.

Benefits of Planetary Hubs:

  • The mechanism is completely protected from dirt, water, dust;
  • Durability;
  • Does not require maintenance and repair;
  • More convenient to shift gears.

Disadvantages of planetary hubs: Substantial weight gain, high friction and low endurance of mechanisms, high price of the bike. With this in mind, it is advisable to use the planetar only in urban driving conditions and on suburban highways.

Speed ​​bikes

The high-speed bike has a multistage transmission, which fundamentally distinguishes it from the classic one-gear bike. A big problem for singspeed (single-speed) is steep and long climbs, especially without perpendicular slopes. The low gears of the high-speed bike reduce the speed, but make it possible to overcome the hills without additional power costs. High gears allow you to accelerate the bike on level ground, and it will outperform singlespeed in speed.

Advantages and Disadvantages of a Speed ​​Bike

For trips around the city on flat roads and simple rides in parks and embankments, the presence of a high-speed bike is not essential. A simple one-gear touring bike is fine here: it costs less and does NOT require frequent maintenance.

Another thing is long journeys on highways, dirt roads and, even more so, off-road. Here you will need a more stable bike, which will pass under any conditions, save energy, and make the trip more comfortable. A long tourist route on single speed will present itself, to put it mildly, difficult, although, in principle, nothing is impossible comments.

Compared to a single-speed model, a bicycle with a multistage transmission has several advantages:

  • Climbing in low gears;
  • Less power costs in a headwind;
  • Acceleration on flat areas;
  • Maximum precision in adjusting the bike to specific riding conditions (especially on models with a lot of gears)
  • Constant cadence, less fatigue;
  • The braking system of speed bikes is more powerful than singlespeeds.

Let’s see from the other side, where the single-speed models outperform their rivals:

  • The bike is cheaper;
  • Undemanding to maintenance of the transmission: the chain and sprockets are designed for almost the entire life of the bike;
  • If the chain is replaced, it can easily rub against the old sprockets;
  • Singlespeed gives a good workout for all leg muscle groups while lifting;
  • Allows you to develop high frequency pedaling skill.

The controversial advantage of the single-speed model is the reduction in weight due to the absence of switches and cassettes. Only valid when comparing identical models with and without cassette. Places in one row, for example, a light road bike with speeds and a steel roadway in this sense is wrong.

Tips for choosing a bike with speeds

Today, high-speed bicycles prevail on sale, so there is plenty to choose from. All classes fall into this family:

  • MTB;
  • Hybrids;
  • Road bikes;
  • Road bikes.

To choose the right speed model for yourself, you need to decide where and on what routes you plan to travel. For example, for city driving, it is not necessary to take a professional mountain or road bike with a lot of gears, a classic road model or a bicycle on a Planetary hub will be enough. However, the latter are distinguished by an overpriced.

In addition to the purpose of travel, cost plays an important role, and both of these factors are closely related to each other. For trips in aggressive driving conditions and tourism, you should not save on the model. you will have to spend more on maintenance and rework. If the goals are modest, for example, to roll out 50 km a couple of times a week, then you can choose an inexpensive model. it will be economically justified. And of course, we pay attention to brands and fakes for them.

The bike should be comfortable to travel. Multi-speed models make it possible to evenly distribute efforts, to make movement more comfortable. But do not forget about such an important parameter as the size of the frame. It must fully match the height of the cyclist. There are size tables for verification, and of course, We draw attention to our own feelings on the “fitting” of the bike.

Frames are divided into male and female. The latter are created for the convenience of the cyclist to dismount and climb onto the bike. In principle, both male and female frames will be comfortable for men, but women on male frames would be uncomfortable.

Taking into account THESE simple recommendations, you will be able to choose a bike that suits you and enjoy riding for more than one season.

Bicycle rear wheel device. Broken rear hub

The most common rear wheel hub failure is a loose cone or over-tightening. The weakening of the taper leads to an increase in the wheel axle play. If the situation is the opposite, when the cone is overtightened, then the ease of movement of the bike disappears. In the worst case, the characteristic Crunchy sound in the bearings may be heard. Both situations are emergency, so you need to immediately start repairing the rear hub.

Eccentric locking rear hub.

Here’s the back sleeve.

This requires removing the rear wheel. On some cam-lock models, no wrenches are required to remove the wheel. On children’s or budget models, the wheel is fixed with two nuts, so wrenches are required.

To tighten the cone, or to eliminate backlash, you will need: a 17 mm key and a 15 mm key. First, loosen the locknut, then tighten or, conversely, loosen the flare nut until the desired result is obtained. As a result, we achieve the elimination of the backlash and then tighten the lock nut.

Poor quality parts will cause the hub axle to bend or break. Only a replacement for another one, of a higher quality, will be the best way out of this situation.

Main components

A modern bicycle has two wheels, usually of the same diameter. The rear wheel is usually driven and is driven by a bicycle chain.

The wheel consists of a hub, spokes, rim, tube and tire. Sometimes the tube and tire are one piece, i.e. a tubeless tire.

Spoke hubs with spokes ranging from 12 to 48 Prestige bicycles with composite frames are often equipped with wheels with carbon spokes.

The size of a bicycle wheel is traditionally determined by the outer diameter of the tire in inches. that’s 14 to 29 (1 inch = 2.54cm). Mountain bike is usually equipped with 26 “wheels, and hybrid or touring. 28”.

The rear wheels of sports bikes do NOT contain spokes, as they are made of a solid disc. This design increases wheel rigidity and reduces oncoming air resistance at high speeds. The only drawback is the increased windage, which adds trouble for riders in crosswinds.

The durability of a wheel depends on the design of the rim. Here the strength of the rim depends not only on the safety of the cyclist, but also on the speed of movement. Basically, the wheels of modern bicycles are equipped with rims, which in cross-section resemble a box. This shape of the rim protects it from deformation during overloads and protects the wheel when it meets an obstacle.

The simplest rims are made single-walled. The rim profile resembles the letter “U”. After adding an additional jumper to the profile, a reinforced type of rim is obtained. double-walled. Such a rim is stronger, it is less afraid of obstacles and holes on the roads. The most powerful type of rim is three-walled, when another bridge is inserted inside.

Material

In the manufacture of bicycle wheel rims, steel or aluminum alloys are used in most cases. Steel rims are cheaper, but heavier and more susceptible to corrosion. In recent years, lighter composite materials are increasingly used: carbon and plastic.

Bicycle wheel spoke

Very vulnerable element. In addition to the weight of the cyclist, it is subject to impacts on uneven roads. The nipple is used to lock the spoke into the rim. The most common knitting needles are made from steel or aluminum.

The steel spokes must be chrome plated. Stainless steel spokes have proven themselves well. They are durable and non-corrosive.

The spoke consists of four parts:

  • Head The head is fixed to the bushings.
  • Body.
  • Thread. A nipple is screwed onto the thread.
  • Nipple. The nipple secures the spoke to the rim.

The nipple must be of the same material as the spoke. Otherwise, due to electrochemical corrosion, it is difficult to tighten and replace the spoke. The spokes are tightened only with a spoke wrench, in no case with pliers or other handy tools.

Knitting needles:

  • Rolled knitting needle. budget option.
  • The drawn spoke is lighter in weight but more expensive.
  • The flat spoke is the most expensive, significantly superior to other types both in weight and in the resistance of the oncoming air flow.

Varieties of rear bicycle hubs, how they differ from each other

The hub is the base of the wheel. Here is the quality of the hub, its weight and size depends on the roll of the bike and the energy consumption of the cyclist during the ride. Bicycle hubs differ from each other in strength, the presence of additional elements and the level of protection from external climatic factors.

The hub is located in the center of the wheel and rotates on bearings. Collapsible balls or factory-made universal sealed bearings are used as bearings. The bearing carries all the pressure of the bike while riding, so its quality must be high.

Hub by means of spokes connected to the wheel rim. Outdated Torpedo bushings contain a brake drum inside the structure, with the help of which the cyclist brakes by reverse pedaling.

The modern bicycle hub features a ratchet mechanism and a cassette cassette that slides over the drum. On the ratchet hub, the bearings are closer to the center, so the load is NOT evenly distributed. Hubs of this type are installed on teenage or budget adult bikes.

The cassette hub is another popular type of rear hub. It has slots on which a cassette with stars is fitted and is fixed with a cassette nut. These bushings are more reliable, the bearings are further from the center of the hub, so the bike can support up to 120 kg.

The third type of rear hubs is a hub with a planetary gearshift system. It combines the functions of the hub and the gearshift of the bicycle.

The entire mechanism is located inside the hub and is protected from dust and moisture. The chain on a bicycle with such a hub lasts longer, as it does NOT change its position. The planetary hub has a high degree of reliability.

The SRAM 3-Speed ​​Planetary Hub design is very simple. But 5 and 7-speed is better not to disassemble. Planetary gears are installed in a special position. this requires a special tool.

Spitsovka

Spoke is the order in which the hub, spokes and rim are fastened together. There are two main types of wheel lacing: “radial” and “cross”.

When viewed “radially” the spoke does not intersect with the others. When assembling “crosswise”, the knitting needle is crossed with the rest of the knitting needles several times, depending on the selected spoke method. On widespread 26-inch wheels more often use “three-cross” lacing.

Bushing lubrication (maintenance)

A tightly spinning wheel means the hub bearings require maintenance. To get to the bearings on the bushings, you must first remove the stars. This can only be done with a special puller. It is allowed to lubricate the bearings with liquid grease, fill it with a medical syringe.

Teflon-based grease has proven itself well. it is a widely used grease that is effective, versatile, and not the most expensive. However, this grease evaporates easily, so green grease can be mixed with Teflon-based grease to increase viscosity.

A crunchy sound of a spinning wheel after assembly means that sand has entered the bearing, or defects have appeared on the rubbing surfaces. Must be disassembled and re-lubricated or replaced Defective parts.
