Bottom Bracket Cartridge 226 mm

Bottom bracket cartridge - 226 mm wide with 3/16 inch keyway. Replacement for the 1BMS-7 kit or when wider than normal pedal clearance is required. If you plan on using it to replace the one included in your 4 stroke engine kit you will need to make provisions for a chainring. Your options are to make a flat on the shaft to accommodate the cotter chainring or use one of our chainring adapters.

This wide BB Cartridge is for 68mm to 73mm BB's.
