General Cycling Discussion - tri and TT bikes

can someone explain the diffrence to me. They look the same to me and the function is not much diffrent. Also, are there any inexpensive frames for these bikes? are some frames built for 700cm wheels? I seem to like going really really fast so I'm looking into next years road and TT schedule. The problem, i dont have anything close to a TT bike, but if i can be PC enough i can have the school buy one for the club.

Tri-atheletes and time trialists use them quite differently.
The tri position (as used by the run/swim specialists) has less bend in the waists, but is rotated forward. aerobars are used to rest shoulders after the swim, and the bikes should have more stable steering to compensate.
TTers simply get very low, and bend their waists more. There are UCI restrictions on how far you can rotate your posion about the bottom bracket.
They are usefiul for turning an MTB into a touring bike, you dont have to adopt a low position to take advantage of aerobars.
They also work better with bar-end shifters than ergo-levers.

there are plenty of tri and TT bikes built w/ 700c wheels.

and what kinda school buys bikes for you!!??? i gotta apply to that school!! ;)

I go to rose-hulman, and am starting a cycling club, and have a little funding, so i figure why not try and suck some more money into the club for a TT bike... it would be rather large though, seeing as i ride a 61cm allez...
