Bought a new Mavic wheelset with Specialized hubs some time ago. Slapped a used Shimano 10spd cassette on it and experienced some skipping in shifting. Took to the shop and they pointed out that the cassette didn’t rotate exactly parallel to the wheel. It’s orbit was tilted away from center. My mechanic tried to shim it and suggested I needed a new cassette. I just bought another used one and the same thing is happening. Me thinks it’s not the cassette. Have any of you’s had this happen before? Does it need a new hub body?
