Details. - Fits Truvativ GXP and Howitzer external-bearing bottom brackets with spline/notched cups (also fits Shimano HollowTech-II bottom brackets). After going to some local bike shops, and being turned off by employees who know less than me, I figured I'd buy some of my own tools and do my own work.
