i FINALLY went and got fitted for my tri bike today!!! i took it out for a short 40 minute ride as soon as i got home. it feels great! i had read that it's awkward and less stable feeling in the aero position, but it felt fine to me! as long as i wasn't trying to whip around sharp corners, it's great! i have the saddle in an aggressive aero geometry...but my aero bars are set at a slightly more intermediate angle...though i did have the aero bars pushed in towards the center for a more aggressive hand position. the bike flies pretty good! i can't necessarily FEEL the speed difference or the difference in muscle group usage...but it was a short ride. i have to say though...my specialized roubaix road bike has much better acceleration...but i guess that's to be expected...it's lighter and i'm able to use my hamstrings more in road bike geometry.
here's what i did NOT expect: the cervelo p2c feels smoother and more comfortable! it eats up small road bumps like a luxury car! that was a big surprise...the specialized roubaix is considered one of the more "plush" rides, with it's all carbon frame/fork/seat post, zertz inserts, relatively neutral geometry, carbon weaving and bike shape to soak up vibrations before it reaches your hands or butt. but my initial impression is that the p2c is more comfy! me likes!
course...now i'm wondering if my roubaix needs a re-fitting or a better seat...i mean, i just expected the roubaix to be a more comfortable ride!
