Don't really know how but I seem to have completely screwed my left crank arm. It looks like the inside splines have all rounded off and I can't get it to fit on properly. Is this just a case of having to replace the whole crank arm (4700)?
Either the metal pinch bolts or the plastic retainer screw came loose. It looks like a replacement to me. What’s the axle spline look like?
