Get aerobars.
I agree totally. For triathlon bike fit / position is everything. You have to be aero, you have to have the steep seat tube angle (cause you get to run after the ride:-)) and you have to be reasonably comfortable in your position which really takes getting used to. Go over to Slowtwitch.com, probably the #1 Triathlon site and join in the fun. P.S. Think about getting a fitting by someone who knows how to set you up. Slowtwitch is a good source for that as well. Good luck!
