QR slippage

Twice now, about a month apart or so I guess I've been riding along and had the QR on my rear wheel slip so the chain side moves down and forward and the tyre slips into the seat stay and I come to an abrupt halt.

After it happened the first time I thought I'd been being anal about ensuring the QR is clamping really tight. Anything else potentially causing an issue or is it just not clamped tight enough?

    Nah, one of these:

    It's only happened twice so I won't switch it for now, just wanted to check I wasn't missing anything stupid. I will double check the threads and keep an eye on it staying tight.

    Take it you don't have vertical dropouts? If you don't I really would consider a Shimano...

    Blingy but rubbish. Shimano use an internal cam which clamps much more securely.

    Ah, fair enough. My old one got rusty so I just got a Ti one to avoid rust.

    Axels are usually steel anyway...

    Get a Shimano, Deore is best value, but XT a bit lighter, much more secure and consistent clamping. Also check the rear dropout for damage!

    yeah good point re. dropouts. will have a look in the AM.

    Will check everything, make sure it's nice and tight and if it happens again will pick up a shimano qr. I will undoubtedly get an XT one to save the grams :oops:

    I did look - but Google said no (to them being available).

    Any other lightweight blingy options with the same internal cam mechanism?

    Old style Tune AC16/17s had an internal cam. Not cheap though.

    €74, so about £65 for the pair delivered, not that much more than XTR.

    Cheers, would only need the rear so will get an xt or xtr one if it happens again. Well probably will get one when I have cash next month anyway to be on the safe side.

    Dropouts seem ok-ish bit of damage but no cracks etc. some of the grooves (knurling?) around the dropout have been knackered as the qr slipped but not too bad

    The grooves are created by the QR, wouldn't be on the frame from new!

    haha.. I did wonder that actually as I didn't remember seeing anything when you see photos of new frames.
