I recently bought a wheelset that supports 11sp and 10sp casettes. The wheelset came with a 2ish mm spacer. I have previously owned a 10sp wheelset that had a 1mm spacer.
I have been told that for 10 speed cassettes I'd need both spacers on the new wheelset, so I put both of them on.
It worked for a while until the wheelset developed some (unrelated to this issue) noise so I took it off the bike, but then I had serious trouble getting the wheel back into the dropout.
Not only did the new wheelset with the spacers not fit into the dropouts, the alignment of the wheelset was off and I couldnt even turn the wheel because it was rubbing the chainstay.
The old wheelset without the casette on the other hand would fit just fine so I thought something was wrong with the new wheelset and sent it back.
Now I wanted to put the old wheelset (which is my trainer wheelset) back on with the casette and only the 1mm spacer.
The problem is that much like the new wheelset I couldn't event get the old wheel into the dropout, so I took out the spacer and it fit first try.
I've used the old wheelset with the spacer in the past and I'm not sure not what I'm doing wrong.
The new (already sent back) wheelset had other issues, but I want to know:
Does this issue indicate a bigger problem with the bike or will I be fine without the spacers ?
What spacers do I need to use with 10sp or 11sp wheelsets ?
What could be causing these problems ?
I have made sure that the length of the hub is compatible with my frame, so that should be not an issue.
