LightWeight Cyclocross Bike #9: Marco's Colnago C50

Heres part two of the "one-two punch". Yesterday, I posted what I am touting as the lightest brakes ever made. Today, I'm posting what could be the lightest cyclocross bike ever made. Marco's 13.16 pound (5.970 kg) Colnago C50!!!! This thing is the essence of sweet. Its blingtastic even. Keep reading for specs...

At just a hair over 13 pounds, this is a fairly incredible bike. And although some very slight upgrades could still be made to this bike to lighten it under 13 pounds, this bike is so very cool.

I got this email from Marco:

Dear friend,
I’m an Spanish CX racer. I’m every day thinking about make CX bikes as light as possible. I now have 5 CX bikes. Today my 5th bike was presented to the public, called “Team Monte Cerrao Evo V”. It’s a Colnago C50 cross frame with lighter parts. As you can see in the scale this bike weighs now 5.970kg. You can find two photos attached to this email.
