I have a Trek 7100 so most of the components are similar. it's surprisingly light. i can get 30+/- mph on it sprinting and i'm not that fit.
I have a 7300 that (since I got my Giant OCR C2), I've turned into a full-blown commuter (Beavertail fenders, rack, full light kit). If the weather's bad, I'll be riding it. On a flat, the best I've been able to do is about 23MPH (and that's really pushing it). On a downhill, I can break 30MPH, and top speed on my commute is about 35MPH down a BIG hill. Average speed for the 22 mile trip (one way) has been as high as 16.4 inbound, with a 16.9 just a few weeks ago. I've got the suspension fork, so I'm looking at swapping that out for a rigid / light fork....anyone have any good recommendations?
