! The first thing you need to know is this is, unarguably and unequivocally, a light bike. On our scales it comes in at 6850g before you add pedals, which means it would be relatively easy to build this frame into a UCI-illegal, sub-6.8kg bike. Lighter wheels and tyres, latex tubes, a carbon bar and maybe some Zero Gravity brakes and you’d be there, figuring out how add weight to keep the commissaries happy.
And for those of you who live in Seattle, “Bothell Bikes”:http://bikesale.com/index.asp?PageAction=VIEWPROD&ProdID=525 carries these. Pretty cool. Streets for about $4500 so not for the faint of heart!
