This 83 mm Sram DUB PF30 bottom bracket is the central component of the entire pedalling system. With its oversized DUB axle, this bottom bracket is only compatible with DUB-format cranksets. Thanks to this essential component, pedalling is smoother and more robust. For long-lasting performance, the SRAM DUB PF30 83 mm features a seal, pre-assembled into the nylon cups. This provides good protection against the elements as well as a longer service life for the bearings.
