What Bikes Have Stretched Out Geometry?
I've come to suspect that I fit best on stretched out frames.
My proportions are top heavy; put it this way, at 5' 11" I can barely stand over a 58 cm road bike, but on this bike, which has a top tube slightly shorter than the seat tube, I set the seat all the way back, use a 100 mm stem, and feel best on the hoods.
What C&V bikes had stretched-out geometry? I'm primarily interested in racy road bikes.

Lemond bikes all have longer top tubes than you would expect.
ie: a 55 will have a 55c-c seat tube and a 56.5 c-c top tube.

Eddy Merckx did quite some streched-out frames, usually combined with long stems.

What Bikes Have Stretched Out Geometry?
Interestingly, old English clubman style bikes like my Norman Rapide or the RRA tend TI have long top tubes. I just measured several this weekend so I know this based on personal observation and a carefully placed measuring tape.

I have the same problem, 6' tall with barely a 32" standover. I've spent a lifetime with long stems riding the hoods. My Rivendell's have longer top tubes and are a lot more comfortable than comparable bikes. My Hillborne is the biggest bike I can ride, it has a 56cm seatpost and 59cm top tube.

I too have a very short inseam and long arms. I found this SR Triathalon from the mid 80's with a 52 ctc seatpost and 56.5 ctc top. Really comfortable and a nice ride. The stem shown is a little short because it was a city commuter and I liked to keep my head up. I think other Japanese makers (Nishiki) made similar versions of these bikes before "tri" design got radical.

Consider yourself lucky. I have a similar physique. I'm 5'9-1/2" tall and I'm all torso with very short legs. I find I can ride any bike between 54cm (21") and 58cm (23"). Being cramped on the top tube is easily solved by installing a longer stem. People who have the opposite proportions (short torso and long limbs) can feel stretched out, and they may already have a short stem installed, and there's no easy solution.

Streached out and relaxed? How about mid '80's to early 90's rigid MTB frames? My late 80's Giant Iguana is relaxed alright, it's a reach to the bars and I'm 6'1". It's by far my sleepest ride.

The prior suggestions are pretty good, basically, you have to keenly review a bikes geometry.
A slack seat tube angle may not help you if you don't need your saddle set way behind the bottom bracket, (i.e., long femurs)
One of the dimensions I try to figure out is the length of the top tube in front of the bottom bracket, a bit of geometry helps in figuring that out.

My Mid 90's Olympia is 56 top x 53 seat and very racy in feel. Actually the first time I rode it it felt like I would just fall over, it's so twitchy and light in the steering.

Thanks. I'm going to measure all my bikes as suggested by

I'm also going to take some pics of myself on a bike and see what you all think.
Perhaps I am over-obsessing about fit. As a practical matter I can ride all sorts of bikes without pain, as long as I get full leg extension. But someday I'd like to have a custom frame built - or take a frame building class and build my own - and I want to really understand fit by then.
Velognome: Streached out and relaxed? How about mid '80's to early 90's rigid MTB frames?
I do feel very comfy on my early '90's MTB (and I think Bridgestones were known for longer top tubes even then). It is pretty much my standard for fit right now. But, I currently ride road.

Steelman built with 72 degree seat tubes and TT roughly .5cm over the seat tube.
Check some of the major brands from the late '90s. Seems like the trend then was for longer TT.

IMHO, a long stem only partially compensates for a short TT. I'm 6'5" ish with a long torso and I sometimes feel like my CG is way too close to the front hub in the jump phase of a sprint.
Also, "relaxed" (aka: stage race) geometry always meant a lower BB to me. A lot of the steel bikes made during the latter years of the "Age of Steel" tended to have crit geometry. Any leads on more classic Italian stage race frames from the mid eighties to the early ninties?

My '86 Gazelle Champion Mondial is that stage race geometry: ST 52.5 cm x TT 55.5 cm (measured c-t-c). Though I think that as the frame size gets larger, the Gazelles tend to get squarer.

I would consider using stems of 12cm instead of 10 if you are pushing your saddle rearward. I ride a 14cm stem on 1 of my bikes that has a long head tube.

My '82 Trek 730 has a 56.8cm* ST and a 57.4cm* TT - it's what they called a 58cm. It fits like a 56cm with an extremely long TT and short HT. At 5'9" I have plenty of standover but the TT is much too long for me to fit on this bike properly but a 54cm would fit even worse. As it is, without a tall quill stem on it and modern bars the drop to the hoods would be unmanageable for me. I can't speak to subsequent years of Treks but I'd guess that all of their race model bikes fit this way through the '80's. I'd also guess that if you stick to searching for bikes that were actually intended for racing you'll find similar geo but that's just a hunch.

Anything from the 30s will have a top tube 2-3cm longer than the seat tube.

Although the dimensions aren't significantly different from my other bikes, for some reason my 78 GJ seems to be more stretched out than the others. So much so that I find a standard 100mm stem to be marginally uncomfortable, and consequently ride with a 60mm stem. If you get a chance, get a leg over a 70's Motobecane that's your size, ST-wise, and see what you think.

I've come to suspect that I fit best on stretched out frames.
My proportions are top heavy; put it this way, at 5' 11" I can barely stand over a 58 cm road bike, but on this bike, which has a top tube slightly shorter than the seat tube, I set the seat all the way back, use a 100 mm stem, and feel best on the hoods.
What C&V bikes had stretched-out geometry? I'm primarily interested in racy road bikes.

So in picking up the '89 Technium PRE, the top tube is stretched 1.5" and gives me the comfort in riding in the drops at will and without limitation. That extra 1.5 is nice once you get the seat and bar adjustments to your liking. The PRE is very nice, very light and quite upgradeable to your liking.

Bridgestone's seem to have a longer top tube than most, especially in the larger sizes. I had a Basso Gap that a really long top tube but the seat tube was too short for me, so try some of the Italian makers too.
