Hi, does anyone know or care to speculate what the trail is for the Colnago C60 (52S). A friend of mine is coming up with some very high numbers via bike cad.

It's probably high and correct. I had a 53 level top tube and the trail was a lot. 43mm rake paired with a slack 71.5deg ht. I think that's a trail of about 6.8mm

I really like that about the bike. It was rock solid on fast descents. I'm not a crit racer kind or rider. I prefer fast, sweeping turns and a stable bike at high speeds.

What are you using for fork length a-c?

I had a C40 and Star fork. Not sure if it has changed much over the years.

Back calculating from stack the a-c is right around 370mm

60+ trail for the smaller sized frames seems crazy. But that is what I am coming up with too.
