Considering that it cost me $1,748 total, that kind of drivetrain and extra's would have been unreachable for me! I had a budget of 1700 and went slightly over.
I figure it would have cost nearly double retail.
It took me weeks of watching ebay auctions to snag that 6700 groupset for on the cheap. (it is all new and take off's)
This was an experiment of sorts, to see if a carbon kitted bike could be built for less than 1700 bucks that weighed no more than 16.5 lbs. Failed on both...but it is close. For the money, I think it is a decent rig.
