I'm a little confused by this head tube I thought the big idea with these one peice headtube and cnc'd sections was that you'd actually increase you welding area because you could make a larger surface for the top and down tube to join to and still only have one join at the headtube. This frame seems to have a seperat headtube and cnc'd section and what looks like a smaller welding surface on the headtube than a standered setup I wouldn't buy one for a least 6 months after they've been released to see how they pan out Chain tension idea is good although thats not exactly new but good on them for patenting it, just put it on some normal frames would you!
