So according to the calculator at competativecyclist.com:
The French Fit (cm)
-------------------------------------------
Seat tube range c-c: 61.6 - 62.1
Seat tube range c-t: 63.5 - 64.0
Top tube length: 55.6 - 56.0
Stem Length: 10.7 - 11.3
BB-Saddle Position: 74.8 - 76.8
Saddle-Handlebar: 57.4 - 58.0
Saddle Setback: 9.2 - 9.6
Seatpost Type: SETBACK
Could an off-the-rack do (perhaps with some modifications...?), or does this demand a custom for comfort on the long haul?
I do not see anything in there about seat tube angle, head tube angle, bottom bracket clearance, front to center, rear to center. Crank length missing, tire diameter missing, trail, fork rake if any.
There are alot of variables that a custom builder will consider, and design around. A stock frame might work just fine, take a couple for a test ride, but remember a spin around the block is not the same as a day or a week in the saddle.
I will run those body measurements through Tim Paterk's program, it has different types of ride types, as one of its parameters for frame calculation. See what it says. Just curious. Just looked at program and Paterek asks for body weight, as well. Please post.
The fit is three points of contact hands, butt, and feet, and distances and angles created. Hand position (reach) is I believe the easist to change, and differnent bars, and or stems. I also think that it is what makes the fit, more than leg extension which can also be changed. I guess this is not much help so I'll cut it short, with fit is not the same as the ride, you can have a perfectly fitted bike, but one that rides terrible, for the use that you require.
