I was reading a French Cycling Magasine, Top Vélo, and I came across this article, on their project light bicycle, which they seem to do every year.
How about road.cc asking to borrow it?
Or perhaps trying one of our own, (and then offering it up for schwag )
I have the full listing of parts in my magasine, but from what I can remember, its:
Cannondale Super Six Evo Frame and Fork. Sub 750g
Skyline Carbon Wheels. Sub 800g for wheelset
Full Dura Ace Di2
Fibula Brakes; £1000 pounds of 138g brakes
Cannondale cranks 450g
Some €200 skewers
And loads of other stupidly expensive, light parts.
Just an idea!
