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.

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.
