SRAM DUB Bottom Brackets are made for the current generation SRAM and Quarq road and MTB cranksets. These cranks use SRAM’s new DUB (Durable Unified Bottom Bracket) technology. DUB cranksets use a 28.99 mm spindle and therefore require specific bearings with this internal diameter. We carry the most frequently requested versions, but If you need a version that you don’t see below, please contact us and we would be happy to get it for you.
