Designed to be used with your X-Type cranksets. Manufactured from high strength aluminum & featuring twice the number of ball bearings than our competitors, Race Face BB cups are also compatible with some Shimano and FSA external BB systems, making for a great upgrade.
• BB Cups are forged & CNC machined from 7050 aluminum.
• Features 35% more thread engagement & thicker walls than the XC/AM BB cups for greater durability in big-hit situations.
• Massive external bottom bracket cups house 35% larger ball bearings than internal systems, yielding vastly improved durability.
• In addition, bearings feature a special “full-complement” construction. This doubles the amount of ball bearings in the cartridge & greatly increases it’s load carrying capacity.
• Bearings feature our new custom triple wiper seal to better retain grease & keep contaminants out and are factory filled with Phil Wood waterproof grease – tested & proven to extend bearing life.
• Interchangeable with select Shimano and FSA external MOUNTAIN BB systems.
