Been having problems with my quick release slipping everytime i put any power down on the pedals, the grip on the quick release nut if fine but the frame seams to be smooth so its just not gripping, any ideas for what i can do?

Bearings seized?

Wheel, gears all fine, its defo the quick release slipping.

Try a better QR. Roughen up the surfaces where it mounts, Tension it more,

Its not a super lightweight cheapo QR is it?

remove grease, use talc.

QR is a hope one, so not cheap one, will try roughening the frame surface,
and give the surface a real good clean, cheers fpor help guys.

track ends, or vertical drop out?

chain tug?
