Hand-built for quality reassurance the CeramicSpeed PF30A SRAM DUB Mountain Bike Bracket outperforms any rival. Featuring an integrated dust cover for all models, a snug and secure fit that fully protects the face of the bearing, the new SRAM DUB crank standard, built on a 28.99 spindle, allows for a more contamination resistant BB design, delivering outstanding performance and stiffness without any sacrifices. The SRAM DUB crank spindle requires the bearing contact points to be in a set and designated width, and all CeramicSpeed bottom Bracket options perfectly match the bearing placement on the crank spindle with the required frame interface for nearly any model of bike. Without the use of unnecessary adapters or spacers, a quiet & stable platform is ensured throughout the life of the CeramicSpeed PF30A SRAM DUB Mountain Bike Bracket.
