Designed to be used with X-Type or EXI cranksets. Manufactured from high strength aluminum & featuring twice the number of ball bearings than our competitors, Race Face BB cups are also compatible with various Shimano and FSA external BB systems, making for a great upgrade.
- BB Cups are forged & CNC machined from 6066 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.
- Bearings feature a special “full-complement” construction. This doubles the amount of ball bearings in the cartridge & greatly increases it's load carrying capacity.
