- Converts your BB30 mountain bike frame to work with MTB cranksets using a 24mm diameter spindle — with no weight penalty to traditional thread-in BB cups.
- Press-fit bearing cups works like an external type headset.
- Precision CNC machined to accurately match BB30 press-fit diameters.
- Positions the bearings externally with exactly the same wide spacing as threaded external mountain BB's.
- Uses new Race Face X-Type Team XC bearing technology.
