SRAM T47 DUB Road / Road Wide Bottom Bracket Cups T47-68-DUB

The SRAM DUB™ (Durable Unified Bottom Bracket) bottom bracket series has two simple tasks: To connect and support the crank arms and to ensure permanently smooth power transmission to the derailleur. To make this possible, SRAM has designed the DUB™ crankshaft to be the central unifying component.

An oversized crankshaft for all bottom bracket standards, better crank arm compatibility, better protection from the elements and for a longer service life.
