Hand-built for quality reassurance the CeramicSpeed PF30A SRAM DUB Coated 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 SRAM DUB crank, 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 and stable platform is ensured throughout the life of the CeramicSpeed PF30A SRAM DUB Coated Mountain Bike Bracket. The CeramicSpeed Coated bracket can last three times longer than other bearings thanks to the hardened-steel races and ceramic balls that are 100% smoother and 15% harder than the ceramic competition. The bracket has a metallic coating 3 microns thick laid onto the races, making it smoother and harder than any other bearing on the market. The result? A bracket with remarkable low drag and exceptional life span.
