For 41 mm Pressfit mountings (BB92; BB89.5; BB86.5)
Adapter inner bearings for 24 mm cranks; X-Type ball bearing
If youd like to use a 24mm crank on a BB92, BB89.5 or BB86.5 frame, the Race Face BB X-Type BB92 Convert bottom bracket will help. It is lighter than standard outboard bearing bottom brackets and has a CNC-machined aluminium shell. Plus, it comes with X-Type bearings that are sealed and thus optimally protected from corrosion. Compatible with all Shimano, Race Face or FSA 24mm cranks.
