ZTTO MTB Bicycle Chain Guide Drop Catcher BB Mount Adjustable

High-strength nylon block

Some people think that plastic is not good, but it is not true. The strength of the anti-collision block is designed, if necessary, it needs to be broken to absorb the impact to protect other parts, and it is cheap and replaceable.

Bearing Wheel

In fact, this wheel rotates a lot. So unlike other brands that use DU in this position, we use better bearings instead of DU to ensure the smoothness of the wheels. The most exciting thing is that it can be moved to suit different chainring and frame.

BB mount adapter is included

Adapter Thickness: about 3mm
Center hole diameter : about 35mm
