I'm only 5 91/2 and shrinking
I inherited longer legs from Pa and shorter torso from Mama. Solution for fit — asymmetrical frames. Or as in the case of one my favorite rides, a smaller frame with a very hight seat-post and a
Nitto Technomic stem. At my height, I have options within a fairly common stock of C&V. My favorite it is a very rare bike — a
Simplon with 56 ST and 54 TT.
Looking at your personal specs, this is my thinking — and I am not trying to be a smart-ass or clever. Rather ... I am thinking now about what I have considered for myself. Instead of having (in my case) four bikes with four fits, might it have been better for me to have contracted a builder to make ONE lugged steel frame for me that was perfect for me in the three basic riding positions — on the bar tops, on the horns, in the drops.
I expect that you will not select to do this — most of us don't. We scour the planet for our own private grail or something that captures our imagination in the old production. I expect many of us end up compromising somewhere. Besides custom frames are usually expensive, although in Sendai I can have one made by Mr Matsumoto for about 100,000 yen — from really nice tubing — braze filled or brazed lugs.
Just one thought, one more option with reasons given. Good luck. The hunt is all part of the thrill in C&V.
