  • How do I properly torque my XD-15 bottom bracket?

    The most important part of setting up an XD-15 bottom bracket with Angular Contact (A/C) bearings is getting the preload set correctly. Briefly, these bearings need to be preloaded 40-60 inch lbs. or 5-7 Nm. This is about 5x the torque setting of a standard radial bearing.
