My objection was to the blanket statement that's it's (100%) marketing hype. There could indeed be a great deal of marketing hype, but, as in my "case", it depends. <<Phil Brown earlier stated that he had done the above experiment and concluded that he couldn't feel a difference. >> It would be easier to draw a conclusion from this knowing the gauges. If they were 1mm stays, I'd have to agree it would be a hypothetical rather than a practical effect. That said, if one was trying to build in a certain amount of "spring" there's a certain risk that something else would get compromised as it would likely only produce the result with the lightest possible tubes and that may change with frame size. My guess is that trial and error engineering would require several frames be built, starting with the thinnest possible tubes, evaluating that one, and progressing to slightly heavier tubes to see at what point the effect disappeared, for each size frame. If I was committed to the bent stay idea and wanted to build a "brand" around it, it would make sense to go to the considerable effort to figure all this out. Frankly, I'm with you. I like straight stays. The first really cool bikes that made an early impression on me were late 50s early 60s Italian racers (Frejus, Bianchi, Ideor, Olmo Ghiradengo), followed by 1970 Colnagos (thank you Peter Rich) and the Albert Eisentraut's I saw at the races. Clean, simple, race bikes. The bikes I've built have been along those lines. Phil and I are both in Northern California and I look forward to meeting him someday. Stevan Thomas Alameda, CA
