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)
ZTTO Thread Lock System
The cups are threaded together inside the frame, ensure that you avoid any creaking sounds. Also make installation and removal easier. Dual silicone seal keeps the contamination out for longer life, ensures water and dust resistance. Thread lock system can protect the frame, more power output, it's better than ordinary structure bottom bracket.
