Frame is columbus nobium tubing from Nova. Fork is from a buddy that owns Fezzari bikes. Because the team weighs in at just over 200lbs I wasn't concerned about failure of fork or wheels. I bought a duraace bike off the classifieds for $800 bucks. Used all the components on this build. Found another crank online for $125 and a set of road bars for the stoker. Getting the rear triangle set up was the hardest part. Getting clearence for the connecting chain ring and clearance for the tire took some mock up but I think it was worth it. A couple of carbon seat posts and bars and some light pedals in the rear would drop a couple of pounds. I think the frame weighs in without BB at just over 6lbs.
