My Colnago C40 still remains my favorite for racing, but the time has come to add the latest to the stable.
Engineer here, IMHO a frame is a frame, a simple structure of tubing with a bit of finite element analysis thrown in to address stiffness, weight strength. No rocket science, more a matter of fashion.
I'm leaning towards a C60, but our local Trek dealer is a good friend, so the Madone 7 is a possibility.
Colnago C60, heavy frame, very durable, great paint job, good heritage, maintains its value.
Madone 7, light frame, nice features, some users report cracks, won't hold its value as well as the C60, but almost $2,000 cheaper.
BTW, as far as durability goes, I churned this squirrel through my forks at 26mph, sounded like a jackhammer. Thought I lost the fork, went through it with a magnifying glass, no damage. Not sure if I would be this lucky on something else?
