Body Change Fit Change Evolution

Got to thinking about how my body position has evolved over the years and realized I am fitting longer than in the past. The breakdown:
20's something rode a 56cm top tube with 74 seat and 73 head angle, 110mm stem
30's something rode a 57 top tube with 74 seat and 73 head angle, 100mm stem
40's something rode a 58 top tube with parallel 73.5 frame angles, 90mm stem
50's something ride a 59 top tube with 73.5 seat angle and 72.5 head angle, 100mm stem

I suppose the change amounts to perhaps no more than a centimeter in length, but coupled with wider bars, 44 vs. 42, the overall feel is so much more open and relaxed on the newest fit vs. the older fits. Anyone experience this evolution to a longer fit rather than a shorter, more upright fit?

I prefer a slightly shorter fit than might be considered technically correct. That was due to neck pain from an old injury. But a recent shoulder injury will probably reinforce that preference.

So I put a shorter stem -- about an inch shorter, end to end -- on my 1980s road bike. Much better. I may swap to compact drop bars too.

I thought maybe I'd lost some height due to spine compression, a common problem as we age. But my recent physical showed I'm still 5'11", same as in my 20s. I just stoop more now due to the neck pain. So I'm working more on upper body conditioning.

i would suggest that your old bikes never fit you "correctly".

For many years I rode a 54 frame w/100mm stem and it fit perfectly. Now I've lost 2 1/2 " in height and it's almost all in my upper body. Currently riding a 55 w/100mm stem. How that is, I don't know.

The disks in our spine compress reducing our height.

Yes, I know. My loss was exacerbated by a lower back spine issue and 5 yrs. ago a broken neck (bike crash) that necessitated a C1-C2 fusion. The part I don't understand is how I am able to ride a slightly larger frame with same length stem.

Yes, originally that is what I concluded, the early bikes were too small, however looking back at it, my back was in worse condition then than it is now, so the smaller frames must have been a way of addressing the lower back problems I suffered through with the exception of the 20's something bike. Racing then and the bike was a 56 with 3cm of drop to the bar with the stem at max height. Some days I couldn't handle that little of drop, but the go faster kid in me didn't want to look like a tourist with a Technomics stem! The vanity of youth is often willing to punish the body without relenting in the pursuit of pride.

Yah, you got smarter, stronger, and figured out how to be more comfortable. I did a mountain ride last weekend with an exercise physiologist, PT shop owner. She's retired, maybe 65, has the longest fit I've seen in a while.

I'm definitely going for a longer fit now than I used to. When I got "serious" about cycling in 2010 I rode a 52 cm frame (I was 5' 7.5" then, probably closer to 5' 7" today). Today, all my bikes are 56 cm and even a 54 seems cramped to me unless I go to a pretty long stem.

But I'm much fitter than I was, I've lost about 50 pounds since those days and I really like my torso stretched out when I ride.
