I'm actually in the process of building up my new Six Carbon frame :-)
It's my 3rd cannondale. 1st was a 2003 CAAD7, next was a MTB (2007 F4)...now this..
I love cannondale's products...most of the clothes I have are cannondale too (domestique bibs, gloves, various jerseys)...can't beat the lifetime warranty they have on everything. I'll continue to buy from them as long as they keep making such awesome stuff..
