What TT frame?...

I did like the Planet X TT Stealth frameset (good VFM), but on principle, he can poke them 'where the Sun don't shine'!

I like the Orbea, Argon and Felt frames, too. Pricier, I know, but that's what principles do for you! :oops:
Anyone got any thoughts of these, or others?...
How do TT frames relate to road frames, size wise? Can I use my old bike fit measurements, or not?

TT frames are all about top tube length

What's your beef with Planet X?

i've got a 54cm Felt F3 road bike with a 545mm top tube with a 120mm stem

my PX stealth is a small, with a 510mm top tube and a 100mm stem

i'm 5'7" with a 30" inside leg....

I'm similar size, and have a 54cm winter bike, 46cm (compact) 'best' bike & a 52cm hack.
I'd have thought a longer stretch would have been required, to get low and aero... apparently not!
I live n learn.

ideally, you want to have your chest over the steerer, and be over the stem with your tops of your arms dropping vertically from your shoulder with elbows at bending at 90 degrees, then your ams out in fron on the tri bars.... TT bikes are smaller fit than road bikes because of this .

The worst thing you can do on a TT bike is go too long on the top tube, as you can't shorten it and you will always be too streached out to get a proper position
