So here's the situation. I just bought a hybrid bike for commuting in the city (Raleigh C40). I bought the hybrid for the cushy seat, comfortable ride, and low price. I've been commuting a mile or two each way (short but harrowing trip through Manhattan rush hours) and while I am very comfortable, I'd like to ride faster. I see some people on road bikes whizzing by me seemingly with little effort, and to my satisfaction, I blow by some delivery guys on their MTB's. So I'm halfway, and I'd like to know what makes a road bike faster, so I can try to emulate some things if possible. Here are my theories:
1. Frame geometry/seating position. -- The geometry of the frame forces you to ride more bent over, reducing wind resistance? Frame technology that is designed to reduce wind resistance in and of itself? (Or is that just Lance's and super high end bikes?)
2. Overall weight. -- Lighter frame, thinner rim/tire, lighter components?
3. Thinner rim/tire. -- Less rolling resistance lets you get more distance per pedal?
4. Or is that all a myth, and I'm just slow because I'm new to bike commuting and not in shape yet?
If 1, 2, or 3 are the case, then I can try to find ways to go in those directions, but if it's 4, then I'll just keep pumping away and getting myself in shape. I'm assuming it'll be a combination of all 4 (plus other things I don't know), but are there some things I just can't achieve on a hybrid bike?
Thanks for your wisdom.
