SRAM DUB Italian (70mm) Threaded Bottom Bracket
SRAM DUB Italian (70mm) Threaded Bottom Bracket Info
SRAM DUB Italian (70mm) Threaded Bottom Bracket is built to pair directly with SRAM's DUB crankset standard, delivering a reliable, low-maintenance interface for Italian-threaded frames. The threaded shell design means installation is straightforward and long-term serviceability remains simple — no press tools required, no frame stress.
DUB — short for Durable Unified Bottom Bracket — uses a larger-diameter spindle than traditional standards, which SRAM designed to improve bearing life and reduce flex at the interface between crank and frame. At 70mm shell width, this bottom bracket is sized for the Italian-threaded road frames that remain common across both production and custom builds.
