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.

I ordered the 206mm first and found it not wide enough for a huasheng 4 stroke low in a felt/phantom style frame. It's so low I ordered a smaller sprocket and adapter here as well. I then ordered the 226mm and have less then a half inch to spare on my transmission side. This makes most kit brackets look like a joke. Like all the parts I received from here these brackets are very good quality.
