The bike is built by a local S. Cal builder/racer Dave Arnold. The three main tubes are oversized Easton Scandium with Easton carbon seat stays and Reynolds fork. I'm 6'3" and around 205 lbs, and this bike fits me like no other I have ever ridden. It's not the lightest thing on the road at slightly under 18 lbs, but I don't mind sacraficing some weight for the performance. It is the best handling and most comfortable bike I have ever ridden.
