Pinion Gear-Bafang Steel BBS 01/02

(1 customer review)


Bafang  style steel pinion gears have gone through a number of revisions since they were first made.  Namely, the fit up to the pinion support plate, either 10mm or 12mm and the gear end that mates to the large chainring gear. To determine which pinion gear to order, measure the shaft end to see if yours is 10mm or 12mm. Then look at the end of the gear to see what markings are visible or blank. Make your selection below. Read the selection as (marking – Size)

    This heavy duty 12mm pinion did work with the 12 mm plate in my version A BBS02 which had the 10mm pinion. I was told that I could not upgrade from the 10mm to the 12mm by others but it worked as Doug says it will above. Crazy fast shipping too, thanks!
