Hi guys, in a bit of a muddle and a newbie.
I have a fixed gear Schwinn Madison currently sporting some square taper Lasco cranks, the problem is that the left crank arm mounting hole has started to round off, the bottom bracket itself is fine.
Is it just a case of getting a new 5 arm square taper crankset or is there other things i need to take into consideration.
grateful for all help.
