So I've just about had it dealing with squared taper bb and cranks, to where I'll probably switch back to using cottered instead lol. It's probably my fault over-torqueing them, cause they fit further down the spindle each time, maybe my monkey brain needs steel cranks to sleep sound at night.

As I'm looking for a used crankset to finish my build. Seems about every square taper has been mangled in some way already and there is few options.

I am converting from a 3x front, I wanted to make it a 1x or 2x, but the chainline is way too far out. So I need a shorter bb and or cranks.

I came across this octalink crankset with bb. Asking price 80eur, is that a good price? it's about as close to what I need for my current build.. Is octalink more foolproof than square taper, could this be mangled in some similar way as square taper do? Or should I look for hollow cranks instead?
