I had a first ride on my steel frame today, and at one point when I had to set off from a stand still and put pressure on the right pedal, the chain tension managed to pull the right side of the rear wheel half way out of the campy dropouts, so the wheel wasn't centered in the frame. I put it back and tensioned the quick release lever as I used to, but it happened again. So I tightened it a lot, and that helped.

Do steel frames need metal quick release levers? Mine has a plastic nut and I'm thinking that might be why it's slipping pretty easy on the steel surface.
