Truvativ Descendant DH DUB 12 Speed Crankset

Blending the experience of countless DH podiums, big mountain competitions and film sessions, the new Truvativ Descendant DH crank brings clock-beating weight savings to freeride burliness — at a price that will leave money for the next adventure.

Forward thinking and backwards compatible DUB™ BB/Crank technology is the workhorse without restraint. Designed for the most discerning pros. And riders who set it and neglect it. DUB™ is compatible with all major bottom bracket standards. Offering better sealing than ever before, without having to make compromises to fit all frames. Yet it opens the door for a new crank spindle for the world’s all-time lightest crank set. It’s a new approach that embraces the old. And it’s about time.

After extensive research, Sram unifies the diameter of bike crankshafts and inner bearings to 28.99mm from 2018. The new bearing technology DUB (Durable Unifying Bottom Bracket) sets new standards from now on.
