so, I searched treats and 1977 and couldn't come up with what I am looking for.
I was suprised to see my 1978 Motobecane 51V has a 10mm rear axle. It's hard to tell from the photo but it's bent.
Anyone got one? Or could point me in the right direction on where to find one? Dimensions are:
168mm rear axle 10mm thread diamater
