hi all, just a quick question while i'm at work...
i replaced my tired and worn ritchey wheels with a new set of mavics, and seeing that i'm still running first gen ultegra 8speed, i had to use a mavic 2mm spacer behind the cassette to make the lockring hold the cassette nice and tight. all standard stuff, except i didn't adjust the RD at all.
i'm finding that it feels like the chain slips and then re-engages in some gears, mostly running the chain across from the 39f to the smaller cogs at the rear. nothing ever slipped like this on the old wheels so i'm thinking that the cassette might be sitting slightly to the left or the right of where it was on the previous wheel? is this good science? it seems to slip under pressure (standing to sprint) and sometimes just repeatedly in the lower half of the cassette. doesn't happen so much in the big chainring.
would just adjusting the stops to move the cassette slightly in or out be the obvious answer here? thanks in advance all.
