List of Common Bike Repairs: How To Properly Repair Your Bike?

how to fix a bike

Before going on any bike ride, or even going on a short trip, it is very important to have the skills of common bike repairs. Yes, this may not seem very realistic, especially for beginners, because there are many important details that you should check before setting off on the road. But today you will have a chance to learn more about repairs because we will show you a list of common bike repairs that every beginner should know.

Bicycle Repair Guide

And so, now let’s move on to the most important thing. When compiling the most common bike repairs, we included the important parts of the bike, which should always be in good working order, and described all the important points in the most understandable words. This would allow even a beginner to make repairs on their own.

Frame

DIY bicycle repairs

The process of caring for a frame is, first, in keeping it clean. That is why it is extremely important to completely clean the frame of foreign dirt and dust before rebuilding the bike to avoid problems with dirt particles getting into the working mechanisms.

Inspecting the most delicate and damaged areas for cracks or chips is a necessary step to avoid future problems. Experienced cyclists advise that the following parts are especially carefully inspected: head tube, bottom bracket tube, rear suspension, and upper stays of the rear triangle. If scuffs or chips of paint are found on the frame, then they must be quickly painted over: spray paint does an excellent job with this task.

Steering Column

The nuances of the column bulkhead process directly depend on its type: if in integrated columns operating on industrial bearings, it is enough to change the lubricant promptly, then for a semi-integrated ball bearing column it is necessary to replace worn balls on time. A clear signal to replace a part is considered to be the characteristic creak of the head tube and the difficulty with turning the wheel.

Suspension

Basic bicycle repairs aren’t complete without fork maintenance, namely changing oil, oil seals, pistons, or springs, as well as regularly cleaning the feet and boots from road dirt. Experts note that in the process of caring for the suspension, it is extremely important not to damage the ring springs, which would serve as a kind of protection for the fork from foreign dirt and dust particles.

The suspension is a rather delicate mechanism and requires special attention, so the craftsmen don’t recommend sorting out or repairing it yourself. And if the owner himself can carry out the current care, then the bulkhead of the cartridges should be entrusted to a professional master.

Drivetrain: Chain, System, Cassette, Ratchet, and Gear Shifters

The bike chain is the second part that needs regular maintenance. If there is a special lock on the chain, removing the chain isn’t a problem, but even if it is absent, it can be easily removed using a special chain squeeze. Cleaning the chain from dirt, lubricating the rollers, and checking the tension are elementary but necessary maintenance of the chain.

The system is cleaned, as well as the chain, using a special solvent. And when assembling it, it is extremely important to observe the correct setting of the stars: so that the special pin in the middle star looks at the carriage.

The cassette, that is, a set of rear sprockets also needs regular cleaning with a solvent from dirt and dust. With the help of a special device ー a puller, the process of removing and installing the cassette isn’t difficult even for an inexperienced cyclist.

For the ratchet bulkhead, a similar principle works: the industrial bearing is simply washed and relubricated, and the ball bearing is checked for damage to the balls, they are changed if necessary, washed and lubricated. This maintenance guarantees a significant improvement in the overall performance of the bicycle mechanism.

Since the ride comfort depends on the switches and their adequate operation, their bulkhead should be carried out especially carefully. The correct positioning of the machinery relative to the system and the cassette stars, as well as the correct adjustment of the screws limiting the foot travel is the required minimum adjustment after the bulkhead. In addition, it is important to lubricate and clean the torsion and tension springs of the rollers in time, and also to check the degree of tension in the cable.

Braking System: Calipers, Hydraulic Lines, Brake Levers

bike repair basics

Since brakes are a guarantee of traffic safety and preservation of the life of the cyclist, timely care of the braking system can be considered basic bike repair. It is carried out in three directions:

  • Bulkhead calipers, checking the condition of the pistons and replacing them, if necessary, with new ones. Difficulties in the work of calipers are noticeable to the naked eye: usually, it isn’t strong enough and too long braking and the failure of the handle. Finding the cause and fixing it would solve all problems.
  • The design of the brake lever is primitive: the body, the handle, and the piston but there can also be difficulties here, for example, with o-rings. If necessary, the craftsmen replace both the pistons and the O-rings.
  • The bleeding brake fluid in the brake lines is a normal process for rebuilding a bicycle. Loss of homogeneity of the pumped liquid can lead to disruptions in the adequate operation of the braking system, and a timely replacement guarantees the safety of the cyclist and reliable operation of the entire braking system.

Wheels: Hubs, Rims, and Spokes

Since the wheels are considered to be the most loaded part of a bicycle, then a little more attention should be paid to them. A timely bulkhead and maintenance of the bike guarantee not only comfortable riding but also a long service life of the mechanisms. Bushings with industrial bearings can rarely be overhauled, once every two seasons is quite enough: this can be explained by a large margin of safety. But mechanisms with ball bearings should be sorted out once a season in order, if necessary, to replace balls with dents or scuffs.

In the pursuit of bike lightening, manufacturers often skimp on rims, making them less and less durable. This can lead to such an unpleasant phenomenon as rim run out: for example, the traditional axial (figure eight) or radial (in which the wheel resembles an egg). This problem is corrected using a special key for the spokes: after removing the tire, the spokes are pulled in the direction opposite to the curvature.

Bike Repairing Tips

Here are some more useful tips on how to fix a bike:

  • Most of the threaded connections in the bike (as, in general, everywhere else) are unscrewed counterclockwise and clamped clockwise. But there is an exception ー this is the left pedal thread. The left pedal is unscrewed clockwise and tightened counterclockwise.
  • There are quite fragile parts in the bicycle. You don’t need to exert maximum effort when working with parts that you have never repaired before.
  • It happens that you cannot remove any part with your own hands or loosen the connection. In this case, it is better to ask a knowledgeable person for help, believe me, this is much better than breaking a bicycle. And in the future, you would already learn how to cope with a problem area, and intervention in this node would no longer require additional help.
  • If you are about to fix your bike, it’s best not to rush. The repair was done in a hurry usually requires another repair.
  • Prepare a place to work. It is better if it is a specially equipped corner in which you would keep it clean and use high-quality devices for lighting. Although repairing your bike isn’t daily painstaking work, it is better to do it in a special place.

Well, now you know about all DIY bicycle repairs, which you certainly can come in handy at any time. We recommend that you carry out such a technical inspection of the parts every 2 weeks. If you see that there are some serious breakdowns or malfunctions, then, in this case, bike fixing should be referred to a specialist. And only after that you would probably be confident in your bike and hit the road!
