If the rear limits are set, make sure the wheel is set correctly, sometimes when you re-install the wheel is sits slightly off , so make sure it's in there correctly. Did you replace the chain also? if so, the new chain and cassette are slightly wider (minimally speaking) since there is no "wear", the rear drive is a tiny bit wider. You should be able to take chain rub by shifting to the big ring , pedaling with one hand (bike is on stand) and adding more tension on the wire by unscrewing your front barrel adjuster until the chain rub disappears- if there is no more adjustment at the barrel adjuster, undo the wire at the FD attachment clamp, screw the barrel adjuster all the way in, then pull the wire tighter and attach to FD. Go to the park tools web site, repair section, and look under "front der indexing". Read them carefully, step by step.
I just went through this when upgrading my RD, cassette, FD and chain.[/QUOTE/)
I did replace the chain as well. I can easily ride - just hate the noise of the chain rubbing. I will look at things when I get home. The Park tool website looks very helpful as well. Thanks.
