The series pedalier cartridge SRAM DUB has a simple job: connect your bielas and ensure smooth and durable power application to the transmission group. To allow that unique approach, we have designed the DUB axis to be a true unifying component. A large axle to work on all the pedalier axle standards. For better biela compatibility. For better protection of the elements. For more durable performance. To be stronger, softer, simpler. Now, back to the race.
Gutter Seal TechnologyTM seals against the elements. Significantly lighter than the GXP® system. Sealed cartridge bearings available in stainless steel and ceramic versions.
