Looking at buying a new wheel not sure about the size. Bidding on ebay and forgot to measure this at the weekend.. 🙄

Does a standard old skool QR measure up @ 135mm x 10mm?

A standard mtb rear QR dropout’s 10mmx135mm (the QR is like 5 or 6mm but that’s not so important, it’s the wheel axle that counts). so you should be fine with any 10mm standard, not fine with a 12mmx135mm standard but that’s bodgable at worst, not at all fine with anything wider than 135.

cheers!
