Movimento Centrale SRAM Dub PF30

Sram Dub PF30 MTB bottom bracket is a consequence of new developments regarding mountain bike cranksets. With Sram Dub, the new crank axle diameter has been changed from 24mm or 30mm to one size: 29mm. In this way, Sram can even pay more attention to efficient cooperation between the front blades, cranksets, crank axles and bottom brackets.
