Colnago Oval CX

Hi joao,
to be honest I'm not exactly sure why. I have seen a few other time trial frames which have the brakes mounted on the inside. I think it is to have shorter brake lines or maybe it has something to do with aerodynamics or to have the weight of everything a little more to the center of the bike? If anyone else knows please educate us :)

...not educating, just guessing myself here:
In real life, it should not matter how you mount the rear brake. You could, however, argue that -taking the direction of the wheelrotation into account- brakepads behind the 'caliper-mountpoint' will work more 'smoothly'. Otherwise the rear caliper brakes 'againt the grain'. The effect might be more visible when you imagine a rim out of true. On TT bikes, however, it might be all about aerodynamics, where rear calipers are mounted below the chainstays close to the BB shell.

i imagined it would be something like that! more aero and more "compact" thx guys

yes, and you should have seen the saddle that was on it. Saved this bike from being an embarrassment

hahah that's exactly how I feel, it sits now in my upstairs workroom.

And thanks for having good taste when putting it back to it's old glory with period correct parts.

Gorgeous find ! - However, I'd say that a seasoned aero CX frame also needs seasoned aero brake levers (old campy or similar). You also need at least a chain for this - Why not ride it ? Some ideas:
