I've got a bent QR rear axle and am looking for a replacement. Seems that these come in 9.5 and 10 mm sizes with a couple of different threadings. When I measure the OD of the threads I get around 9.8 mm – can I assume that that means I've got a 10 mm axle?
Is the right way to measure to pull the axle and measure an unthreaded section? Or does the size even matter if I'm replacing the cones and nuts with it?
