I put a set of new wheels on one of my bikes a few years ago. The wheels included new quick release skewers. The skewer on the back couldn't produce enough clamping power to keep the wheel straight when I climbed out of the seat and stood up to pedal up hills. I had to discard the cheap new skewers and buy some good old fashioned chrome steel skewers. The new steel skewers produced far greater clamping force & solved the problem.
