>Pretty sure the "superlight" used in that test is standard diameter (as is >the "standard" ;^) The Roadeo will by light(er)weight but still >oversized tubing. Indeed, the "standard" and "superlight" bikes in our double-blind test were "standard-diameter tubing," while the "oversize" was superlight oversize tubing (0.7-0.4-0.7 mm wall). All three bikes were excellent performers _for the testers_, and better than most steel bikes available today. The "oversize" frame uses similar tubing as the smaller sizes of the Roadeo. >I don't think GP has done any standard diameter tubing designs since >RBW began... Rivendell's first frames were a mix - the first two lugsets used OS top tubes and standard-diameter down tubes. In the interview in Bicycle Quarterly (Vol. 3, No. 4), Grant P. had interesting things to day about the move to oversize tubing. After he agreed that more flex could be better - he quoted a Bridgestone engineer who talked about the ease of jumping from a sprung ballet studio floor vs. a concrete floor - he said: "Aluminum frames need [oversize tubing], because [aluminum] is three times flexier than steel is, and when aluminum flexes, it fatigues. Titanium is twice as flexy as steel... Then, as those materials get more popular, people don't see the reasons for the size, but they associate the size with modern fashion, and the media talks wrong about flex and energy. Then the steel tube makers are doing it, too, just to survive..." At the time, I was hoping that eventually, Rivendell would make a lightweight, standard-diameter frame.
