wheel hits frame

Hi,

I have a strange problem, when I really crank the pedals (e.g during a climb) my back wheel shifts to one side and ends up rubbing against the frame, not ideal!

I have swapped out the quick release skewers for hex key ones, and if I do it up really tight the wheel normally stays in place.

Does anyone know what could be causing this?

    so the axle is slipping?

    fit a shimano Qr.

    changed from a Shimano QR. Yes I think the axle must move as I apply pressure.

    I think the frame might have some flex in it.

    That is how it works anyway. BTW the new axle you put in wasn't bent or anything was it?

    nope, looks fine.

    I meant the frame might have more flex than normal - I had a big crash recently.
  • LOL!

    Have you checked the bike? i assume it only started happeining after the crash?
  • gareth84gareth84 Posts: 94
    yeah, it looks fine.

    Did it only start after the crash?

    Love how this key information was left out of the OP :lol:

    get it looked at then.

    nothing we can do here.

    little harsh, no?

    I got some good advice from another forum:

    - use sandpaper to roughing up the dropout to let the hex key nut grip better
    - try a larger washer

    Pretty bad advice, actually.
    Oh, and erm, check that you haven't broken or bent the frame.

    Get some vertical dropouts, there's some good advice.

    Better, than take it to a shop...

    sandpaper fairly useless at roughing up anything other than wood.

    what will a washer do?

    if it is slipping when a shimano Qr is applied then there is something very wrong.

    given that you did not mention the crash at the start and there has been no mention of the frame or and images etc.

    it could be a serious issue that needs looking at.

    so take it to a bike shop or someone who knows bikes who can advise you what has happened.

    You haven't been putting a wider tyre on have you?

    How much clearance do you have between the tyre and stay normally?
