Bike Hubs Types



1、Iron hubs/Aluminium hubs

2、Quick release hubs/solid shaft hubs

3、Cafei hubs/spin hubs, the so-called cafei hubs, that is, the flywheel is stuck, the hub has no teeth, 

only the tower base, spin hubs are with teeth, the flywheel is spun up, currently on the market, but the flywheel is used more.

4, V-brake hubs and disc brake hubs, the so-called V-brake hubs, means the hubs without disc brake seat, 

the brake with the car is a pincer brake, and disc brake hubs with disc brake seat, can be installed disc brake



The more hub bearings, the higher the strength?

If the front hub is bearing hub, it is generally 2 bearings,

while the rear hub has three specifications of 2 bearings 3bearings or 4 bearings.

In 4-bearing hub, there are only two bearings mainly used for load-bearing in the hub shell, 

so their strength is basically the same as that of 2-bearing hub.

The real significance of bearing hub lies in that the other two bearings mainly support the quasi-rotation of the ratchet. 

The high precision of the bearings can reduce the yaw 

when the base and flywheel rotate and make the speed change more accurate.
