I have sourced this nice fillet brazed frame in France, but the chainstay is so short I am wondering if the bike was meant for 650 wheels. It may actually be Columbus EL with weight of frame at 1865g and fork at 675g but I am also unsure.
Anyway it seems highend as the fillet brazing looks ace
Chainstay is 400 mm
and shortest distance between the axis of the wheel till the nearest seattube point is 344mm
See a picture of the frame and one with a 700 wheel with a 23 tyre
I know that sporting frames have often been designed with very short chainstay for more rigid and responsive behaviour but here the margin is so little I have doubts about it being designed for 700 wheels
Is there a way to make sure ? by the dimension of the fork ?
What do you think ?
