Help please.
I had to replace the rear wheel on my road bike. I removed the newish cassette, and replaced the cassette onto the new wheel.
All went well, but there was a lot of play in the cassette. Then I noticed a spacer came with the new wheel. I wondered if that should go on the splines before the cassette, (I'm pretty sure one wasn't there with the old wheel). I tried it and noe there's no wobble.
So is this normal/optional/important?
Ta.
