CeramicSpeed PF30 SRAM DUB Mountain Bike Bracket - Black

The CeramicSpeed PF30 SRAM DUB Mountain Bike Bracket houses superb quality and hand-built mechanics. Featuring CeramicSpeed Standard Bearings that are installed into cups, the bearings have super smooth, super round CeramicSpeed balls contained in hardened-steel races.  The CeramicSpeed PF30 is designed specifically for 28.99 spindle cranks with a native fit frame interface for minimal excess spacers and zero plastic adapters. The CeramicSpeed Standard 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. These feature a frictional drag of 0.3-0.4 watts per set, which represents an average 75% drag reduction compared to most bb's.
