Help with hed 3 cassette/wheel wobble
I am new to working on my own bike and I have hit a problem with my rear wheel.
I bought a Hed 3 tri spoke rear wheel (clincher) off of eBay. The wheel came without a cassette.
I put a Shimano Ultegra HG CS-6500 9-speed on the wheel. The shifters are Shimano Dura Ace bar-end and the derailleurs are Shimano Ultegra. I used the skewer from my Mavic Ksyrium Elite rear wheel.
When I put the Hed on my bike, it looks like the cassette and chain wobbles when turning the pedals. The wheel itself doesn't wobble (the distance between the brake pads and wheel doesn't change).
Is the wobble normal? Have I installed the cassette wrong? Is the cassette incompatible with the shifters/derailleurs? Bad wheel?
Thanks in advance.
