I have a wheelset that recently started rubbing the left seat stay under hard pedaling. I looked at how the wheel sits in the stay, and its really offset. I pulled the wheel and threw it in the truing stand. Not that I know much of what I am doing, but i can true a wheel that is slightly out of wack. I flopped it, and there was about a quarter inch between the two sides. Question is how much dish need to be there to fit the 10 speed cassette? Can I just loosen all the non-drive sides a bit and tighten the drive sides a bit to pull it away from the stay? Thanks.
