I think it's the bike, too. I have a Trek 7300 hybrid and it feels slow in comparision to my other bikes (older Schwinns). Of course, components and geometry are so different it's impossible to compare and I don't have computers on the other bikes yet.

But I agree, the 7000 series (both hybrid and FX) seems to be, or at least feel, sluggish. Couldn't tell you why, though.
