Hi,
I have a 94 Marin Pine Mountain with a supplied BB which is way to short and the chainrings foul before the crankset is even fully screwed on.
I’m guessing it’s a 68 she’ll but I can measure this. I plan to just buy a shimano UN55 but don’t know what length.
Also the “too short” one has no markings on it to know the length or chain line.
Can I just measure it? I never know if the “length” is physically the overall size or the mystical chain line
Worst case I have one or two I can try but I’d rather not just do trial and error if someone knows the correct length
Thanks
