(I have included my fit coordinates which to me are in Hebrew) The reason I need help is that I am considering the purchase of a Planet X Stealth Pro. I have no idea what size or if I can make that bike fit like my P2. Can you gather this info from what I have given or/??? I have tried looking at Dan’s info, but it makes very little sense to me. I am sort of a hands on guy. Unfortuneately this doesn’t help me in this situation. So I am asking you guys for a little help.

let me get this right. You want to swap a P2 for a planet x?
Will you please hurry up so I can buy your P2 before you come to your senses?

Ummm … those 2 bikes fit VERY different. Why are you thinking of switching? Hopefully not just for “carbon sake.” The Planet X is a surprisingly good bike (just try to find a neg review for one), but only if it FITS you! You must consider this priority #1.

You riding reasonably steep and have a pretty good drop - you would have a hard time replicating your current position on a Stealth (can be done though).

P2SL not P2C. I like the bike, but there are lighter more aero possibilities out there. I was thinking of just getting a P2C since I wouldn’t have to change anything, but it is double the price for the frame. Just thinking.

Thanks for the input. I may need to stick with the P2.

lighter yes, more aero… I guess marginally.

the planetx is a nice bike, but not more aero than the P2SL

and therefore, not faster.

unless its a TT up mount ventoux, maybe

What is the difference in fit between those 2 bikes? (I’m considerong also a Planet X)…

seat tube angle for one (and most important for a tri bike), head tube height, top tube length
