The forum search function is not even letting me search using "jis" and "iso" as words, and I can't turn anything up on google or by adding other words on the forum search.
I've got a Sugino crankset, designed for J.I.S. taper spindles mounted on an old Stronglight I.S.O. taper spindle from the early '80's. I'm aware that Sheldon Brown suggests it is probably safe to do, but I have also heard of people eventually stripping out the square taper. Has anyone on these forums had this issue, which they could provide details about, or has anyone around here ridden a similar setup for at least a year or two without issues?
I'm just going to tighten the crank set on there as tight as I possibly can, make sure my chainline is straight as hell, and pray that the cranks don't fall off until I can find a nice set of 165mm length ISO arms.
