Tri-Athalon/TT bike fit. Same as road bike?Mauceri

I own a Seven Axiom and my frame is a 55 and fits like a glove.

I want to buy a used Cervelo P2 (not P2K) or P3 or GT Vengeance.

There are a few for sale on E-Bay that are 55. Will this fit me?

This link illustrates some of the current sizing and fit issues 'tween road and TT/Tri.

If you've got access to a fit system, or at least have your anthro numbers, you can guestimate your position on these frames (you'll also need the headtube length for the frames you're looking at).

Ironically, I've got two of what you seek...



The GT fits... barely (The P2K is a 61, the GT was sold as a Large running 650C wheelz). I bought the bare frame based on my own anthro numbers... and according to the tale of the tape... it would fit... and if I loose a few more inches round my middle, it should dial in nicely for shorter TT courses (both bikes use a 140mm stem). Both frames sport true TT/Tri geometry (slack headtube with steep seat tube).

Most of my frames (double diamond) are purchased based on top tube length... and indeed, 'tween the various platforms, the variance is probably no greater than 1cm.

We abide.

Remain In Light.
