Durability, Unification, Betterment

Are you tired of so many kinds of bottom brackets? I’m sorry to tell you that here is another new standard.... It sounds good, we agree with durability and betterment, but unification? Really?

We Make It More Unified

DUB not only brings new axle, but also new tools. Why not use a more common BB tool? after using ZTTO bottom bracket, you don't have to worry about there is no tool can fit your bike in local bike shop. we designed it to normal bottom bracket standard, which is same as BB51/52, ZTTO BB109/91. (item not included tool, please check it in ZTTO official Store)

The Best Beyond Ceramic

We know that many people looking for a ceramic DUB bottom brackets, but this is a special bearing specification, we are still working on it. In order to satisfy our customers, we use the top level bearing. it's so smooth.

CNC Precision Machining

DUB requires higher production accuracy, and we can do that. Made of Aluminum Alloy, and this bottom bracket is solid and durable with a long service time. It works well on your road bike or MTB.
