OK I took my measurements and they are:
-------------------------------------------
Inseam: 35.7
Trunk: 25.3
Forearm: 13.4
Arm: 28
Thigh: 25.8
Lower Leg: 22.5
Sternal Notch: 58.5)


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?
