Axel Merckx, Eddy's son, has a similar build--all arms and legs. Eddy and I lean in that direction, but not as bad. I'm 5-11.5 with 35" legs and a 75" wingspan. In modern bikes, I've found 57-58 cm fits well if the top tube doesn't go over 57 cm. I have a '80 Masi, 60 cm with a 57 cm top tube, that fits me perfectly. With the seat clamp reversed it looks like your upper body position is quite vertical and your leg extension is a little short. I'd venture to say you could get more leg extension by moving the saddle back. You might also get more power and better handling with a lower back angle and lowering the stem. Start with the shorter stem, then see if you can use the longer one without crabbing to the front of the saddle as you ride.

One advantage of those old British frames for you is the top tubes on the taller sizes tended to be shorter.

Case in point, a tall British frame with a short top tube. The proportions for the International are more conventional.

Naughty thread bump.
Here's another UK frameset. 531c.
63.5cm / 57cm with a 21cm headtube.

Finding these type of frame proportions is a bit of a hobby of mine.

The way I have the Dawes set up right now is actually pretty comfortable so far (longest ride on it like this was 40 miles). Since starting this thread I have changed quite a bit, but the seat post height was risen because I was having some knee discomfort when it was lower, but that was also before I changed the crankset so I might play with lowering it a touch.

I think the Dawes is 98% set up perfectly, my bigger issue is that Iím trying to upgrade the frame to a nicer one and Iím struggling with what size or geometry to look for with long limbs and a short torso. Iím thinking anything I could make anything from 58-62cm work with the sweet spot being around 59-60cm C-T? But thatís really just a guess. The Dawes is 62cm (24.5Ē) C-T as a reference point.
When going to a smaller frame be aware of your knees hitting the handlebars. Smaller frames by design will bring the handlebars closer to your knees. Your Felt and Trek did what they are supposed to do. They make you stay in very aerodynamic positions which is your upper body almost parallel with the ground. The seatposts are not out too far from what I see being ridden by the high performance crowd here in Sacramento CA. If you are migrating away from these low handlebar positions then coming to terms with that will answer a lot of questions about sizing. If you like your present handlebar setup which is much higher that your previous bikes then so be it. Any new bikes should be able to reflect that handlebar position just as you have it on the Dawes. I really like your old Dawes. Even though it is not top of the line it is still a fast reliable bicycle and you will surprise lots of people who think somehow its the carbon and not the legs.

I've looked at an awful lot of old geo charts, and I have yet to find a common production road bike with the legendary "criterium geometry" compared to today.
