What’s the axle fitment ben?, square taper i guess?.
very unusual but almost reminiscent of the very early middleburn shape, how/where did the left one snap? – on the taper?.
Square taper – but the square is parallel to the crank arm, so a replacement was tricky. Luckily an old Race Face fits, and Silverfish sent me one for free 😉
The left one, I think, peeled apart along the seam at the back.
