Anyone 6'4 or taller please post up what you are riding for a Tri Bike

I'm 6'5" and far from flexible. I ride a 61 P2 and a 61 Soloist. I also have a 61 Duel.

The Cervelo guys travel around in a van and do test rides at local bike shops. It's a great way to demo the latest, greatest bikes. Go to their website and see if there is a demo in your area.

I'm 6' 4", 189 Lbs, I ride a Softride Powerwing 650 Large frame with Large size beam. Makes it a 58" inch frame by their sizing chart. Fits me great, my drop may be a little much for you, but you could easily build this bike to a less aggressive position, that part of the beauty of Softrides, they are ultra adjustable. Pretty affordable as well as far as used tri bikes go.

I'm 6'4" 180-185lbs and ride a L (I think a 58?) Quintana Roo CD0.1.  It's a long and low bike which suits me fine, as I have relatively short legs (35' inseam) compared to my torso.  I do ride steep, though the bike will fit fine if you don't.  I've actually had to get creative to get as low as I wanted to go.  I ended up mounting the extensions under the base bar with spacers to make it so the armrests sit directly on top of the base (at least until I can afford an integrated set) attached to a -17 deg IIRC 130mm stem with no spacers.

Comfy vs. fast.  I wish the angle showed just how much we dropped it.  2mph on the same sprint course. . .mostly through aero gains.

Have you been fit (and do you know what that means)? That will help guide in the decision process. You won't get the exact bike from the fit, but it will tell you the fit position and from that you have the information to find what bikes will work well for you. This is how to "try before you buy" with bikes. You don't actually try the bike, but find the position first. A decent shop should be able to easily switch out saddles or the bars once it's in the store if you have different preferences than what it came with.

I'm an inch under your requirement, but see bikes from every manufacturer that I could fit on. And most all of them are one down from the largest size they have available. Everyone has something I can get onto and be reasonably aero in. What limits me is that I do want a substantial drop, and many are relaxing on this to fit the majority of the population better.

6'7"

61cm Cervelo P3 TT

63cm Felt F75 Roadie

XXL specialized stumpjumper FSR 29er MTB

XL Cannondale Super V 26" MTB

I'm all arms and legs. Also, those are 650c wheels so that doesn't help the appearance.

It fits me well, I'll get a pic up later of me actually on the thing, it doesn't look so crazy when I'm on it.

This is what I look like on that softride

man, we should start a hoop team..., lots of tall guys
