can admin move this to troubleshooting please
can anyone shed some light on what the hell is going on here.
b21e crank has a key
the gear has a slot and another cut out
someone's welded a key into the pully
I thought something was abit wrong here so went to swap on a pully from a b23.
the b23 crank is diffrent it just has a slot and the gear locks into that and the pully
what the hell is going on here haha
does b21 use a diffrent pully and the previous owner just did this to make it work?
