Why is it not recommended to mix and match brake levers and calipers between different brands or models?The first is the problem of brake fluid. If different brands use different brake fluids, the seals used will be quite different. For example, the brakes using DOT oil and the brakes using mineral oil are different in the selection of seals. There is a big difference because the DOT requires a stronger corrosion resistance of the seal.
I generally do not recommend riders to install foot supports, especially riders who like high-speed riding and off-road. When parking, please tilt your bicycle down to the left. Note: It must be the left side, because there is a fragile rear derailleur on the right side of the bike, and the bike is placed down to the left so that you can pick up the bike and step up from the left side (there are not many left-handers, right?)! There are also friends equipped with disc brakes when you put your bike down to the left, pay attention to the disc not to hit the protrusions on the ground to prevent the disc from being deformed by external forces.
1. The mudguard is basically ineffective in riding activities.
2. The mudguard will increase energy consumption during riding activities.
3. will increase the probability of failure. Therefore, this type of mountain bike does not require mudguards. If the subject is only doing slow riding on general roads, you can use a station wagon.
4. The hidden safety hazards of mudguards: general mudguards are made thin and wide, and the materials are mostly steel, aluminum, plastic, resin, and other materials with certain hardness. It's like a knife without a blade. In other words, it is a sharp protrusion on a vehicle. When the cyclist accidentally crashed, the kinetic energy is very large at this time. This sharp protrusion is very easy to cut your skin under the huge kinetic energy, especially in the summer when the riders wear very little and their bodies are exposed. The parts are many.
