my 1st and 2nd are tight, but seemed to work out a bit. I think 90% of it was adaptabilty/timing issues on my part. I had a 1/2 dozen grinds going into 2nd.
5th is tricky.
I guess if you needed the spacer and didn't use it, it wouldn't work at all.
on the postive note, shifting is great and no leaks.
