About to fit a pair of new old cranks square taper cranks, and they are juuust touching the chainstays when pushed in by hand before tightening. I clearly need a wider bottom bracket.
Currently Shimano fitted a UN55 68mm 110mm, how much wider should i go to be "safe" while still keep it reasonably tight?
It is a 90s steel mtb frame, so there is probably some "frame flex" to take in account as well.
