I went to my LBS and he gave me a big story about having to re-index the trainer wheel cuz of the new cassette vs. not new chain. Why not just buy another bike? he says. This from a guy I just bought a beater/mountain bike from (trek 4300). I ordered slicks for the mountain bike! It will be a different feel but I think between the two bikes it will be cool. I will replace the road tires when they wear out and select a more user friendly tire.
