SRAM PF30 DUB Road / MTB / Road Wide Ceramic Bottom Bracket - PF46-68/73-DUB

The SRAM DUB™ (Durable Unified Bottom Bracket) bottom bracket series has two simple tasks: The connection and bearing of the crank arms and ensuring a permanently smooth power transmission to the circuit. 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 longer life.

DUB version with ceramic bearings for ROAD and MTB cranks and frames with Pressfit bottom bracket shells with 68mm as well as 73mm installation width.

Also fits ROAD WIDE cranks and frames with Pressfit inner bearing housing with 73mm installation width.
