OK... I can't understand WHY my gears can't just all WORK without rubbing against the derailer (???) at some point.

I have had it adjusted and the guy at the shop said, "It's just going to do that". Either I get it adjusted to rub in the lower gears, or in the higher gears. But I can't have all the gears running smooth without rubbing.

It's really annoying!!!!

Does anyone else have this issue with their TREK 1000/from 2004? What did you do to fix it?
