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.
