It depends on what other riding you will do. For me, duathlons are my thing this year, but I really love going 70-80 miles on a Saturday morning. Clip on Aero bars and a slight shift in my seat position gets me down where I can be competitive in my age group. If you are doing nothing but Tri's, and you want to be competitve, get the tri bike. If you plan on doing other riding types, stick with the road bike and get some clip ons.
