Boogie7247 - 2009-08-07 8:03 AM I am very new to the game. My Dad is letting me borrow one of his Cannondale road bikes until I can get my own. What is the difference between a road and a tri bike? I have no intention of ever doing a ironman any time soon.
Generally a tri bike is made so that it uses less of the running muscles
(leaves you fresher for the run
) by having a seat tube angle more vertical than a road bike
(which is few degrees further back towards the rear wheel
).
The tri bike will also have aero bars, which allow you to to assume a more aerodynamic posture hence more speed, yet decrease maneuerability and the ability to brake fast
(you have to come out of aero position to use the brakes
). The reason for that is in most triathlon events drafting is not allowed
( although ITU championships now allows it for showmanship purposes
), so you have to cut through the air yourself, and because you are not close to people you don't need the the maneuverability of a road bike to stay out of their way etc.
So basically a road bike is for riding in groups and is easier to ride in hilly terrain. A tri bike is the faster bike solo
(aerodynamically speaking
) and it allows you to run better off the bike.
You'll see most triathletes on very hilly courses, such as ironman nice using road bikes exclusively because there is so much climbing it is easier to use a road bike. You can also attach aero bars onto a road bike, but, depending on the fit this might overstretch you somewhat and cause fatigue if used for along time.
