The LN7922 is a maintenance-free, sealed cartridge bottom bracket with a JIS square tapered spindle designed for single ring cranksets. 

Features ultra-smooth bearings, a hollow cro-mo spindle, and an aluminum body and cups.

Pro tip: The crankset being used determines spindle length, not the frame. Please check what length the manufacturer recommends for your crankset or measure your existing BB's spindle.
