The quick-release system has been used on bicycles for nearly a hundred years. This simple structure "small irons" is widely loved by people for its light weight, strong locking force and easy operation. It is especially important to master the correct method of quick release.

Quick release structure

First, let's briefly analyze the structure of the quick release lever. The quick release is composed of a quick release nut, a handle, a spring, and a shaft. The quick release of the front and rear wheels are also different. The front wheel quick release is short, the rear wheel quick release is long, and the quick release nut surface is densely serrated to be locked. To maintain greater friction, the nut's sawtooth material is also different. Some quick release levers use steel saw teeth, which are more rigid and durable, while some quick release levers use aluminum serrations to reduce weight.

How to properly adjust the tightness

First of all, we must understand that the quick release is tighted, not locked, so we must grasp the correct locking force. Many riders like to adjust the locking by rotating the quick release handle. This is actually very wrong, because many of the cams of the quick release handle are made of plastic or rubber. If the handle is often turned to adjust, it is easy to cause this part. The wear and tear causes deformation and, in severe cases, can not lock the wheel set.

Therefore, we must adjust the tightness by rotating the quick release nut. The nut with the metal serrated is more durable and does not cause excessive wear. So, which point is the most suitable tightness for us?

Here to teach you a very simple method, first, the quick release handle is fully open 180 degrees, rotate the adjustment quick release nut, when the quick release lever is closed to 90 degrees, just when there is resistance, this point is your quick release lever The best locking point, then fully lock the quick release. In addition, when locking and quick release, it is necessary to ensure that the wheel set is completely embedded in the quick release port. The wrong position will cause the wheel set to be biased. In severe cases, it may even damage the quick release and cause danger.

How to remove the wheel set

In order to disassemble more quickly and conveniently, we must pay attention to the direction of the handle when fastening the quick release lever. It is generally recommended that the front handle is upward, perpendicular to the ground, and the rear handle is located between the rear upper fork and the lower fork, so that not only can You are quicker and less effortless when disassembling, and at the same time safer, avoiding the danger of quick release being suddenly opened by impact.

Before disassembling the wheel set, remember to adjust the shift to the minimum flywheel, then open the quick release, loosen the nut, and remove the wheel set. The road bike also releases the brake before removing the wheel set. Some riders often encounter such problems. Why do I loosen the quick release nut and the wheel set can't be removed?

It is very likely that the nut is not loose enough to cause the nut to get stuck in the frame. Therefore, when this happens, do not rush and violently disassemble it. Loosen a few turns of the nut and keep the horizontal position removed.

Quick release precautions

Many riders think that quick release does not require maintenance. This view is very wrong. Quick release is the same as other parts on the bicycle, and it needs maintenance. Occasionally, the quick release lever is removed, and it is necessary to wipe the shaft dry and the nut serrated surface, which allows the quick release lever to maintain excellent friction and prolong the service life.

If the quick-release rotation or the handle turns the cassette, a few drops of oil can be applied to the screw head and the handle, and then the feel can be improved. In daily use, it is also necessary to check whether the quick release is damaged. If the shaft is bent or severely worn, replace it with a new quick release. In order to ensure the safety of each ride, it is a good habit to check the quick release before riding.
