PressFit 4624 MTB
This is the bottom bracket for a mountain bike non threaded frame with a shell width of either 68 or 73 mm AND the internal diameter if the BB shell of 46 mm. If you fall into those measurements and wish to use a 24 mm or GXP crank spindle you can choose the appropriate BB below. We have both Rotor Red or Rotor black cups housing steel or ceramic (red only) bearings. May the force be with you.
