Torsional stiffness, example Klein
Jimbo said of Klein that "they not only figured out the torsional
stiffness thing, but actually acted on it. they deserve medals for that." Can you give us some references, preferably with pics, and maybe you want to spin out a short par so we know to look for precisely what you're referring to. Fangs, Andre Jute Curiosity never killed the cat! |

Cannondale nicked the idea, and I believe Klein sued them. Compare early Al frames, eg Alan, which have tubes of similar diameter to steel bikes, to modern stuff - the Alans were floppy as anything, but we all know that modern Al-framed bikes tend to be stiff. |

Gary Klein is often credited as being the first to offer a commercial big-tube aluminum bike. As far as I can tell, Harlan Meyers of Hi-E beat him to it by a span of years, having brought his frame to market in 1972, a year before Klein claims to have conceived the idea while in college. http://www.wooljersey.com/gallery/v/...geViewsIndex=1 Fat tubes are torsionally much stiffer than skinny ones. This accounts for the relative lack of BB sway in fat-tubed aluminum frames versus traditional steel ones. The problem "jim beam" has is in believing it matters that much. If one prefers the feel of a torsionally stiff frame, a very fat-tubed and not-too-light aluminum frame may be the most cost- and weight-effective way to attain that end. But many of us either don't care or prefer more springiness in our frames. Having become infatuated at one time with the superior stiffness of big-tube aluminum frames, I now feel more or less agnostic on the matter. I believe that there is far more difference and more benefit in a stiff crank and BB spindle, since using these has made various otherwise inadequate skinny-tubed steel bike frames more than acceptable for my own use.

Chalo Didn't Sheldon once (or more often) mention that his wife Harriet had built a fat-tube Al bike herself while attending college with Gary Klein? |

If the bike lasts, and it's equally efficient within applicable tolerances, then it's a matter of taste. Really. Steel bikes are proven. It's fair to say that aluminum bikes are proven by now, too. Some prefer the steel ride and some prefer stiff aluminum. My experience with both doesn't conclusively favor one or the other, but I have cracked more aluminum frames than steel ones. (Not particularly lightweight ones, either.) When I ride a fat tube aluminum bike, I like it. When I ride a traditional diameter steel bike, I like it. When I ride a fat tube steel bike, I like it. They feel different, but none seems clearly better in one way without seeming less good in some other regard. I have encountered satisfactory and deficient examples of all three.

If the bike lasts, and it's equally efficient within applicable tolerances, then it's a matter of taste. Really. why don't you and andre just **** off together and create homoerotic "art"? [you're an "artist" aren't you chalo?] because all you're doing, without any spark of originality or independent thinking [and /definitely/ no attempt to educate yourself] is simply humping andre's completely engineering-free bull****. Steel bikes are proven. yeah! proven heavy. proven fatigue vulnerable. proven corrodable. and in many cases, proven ridiculously over-priced given the materials and ease of fabrication. surley "lht"??? that thing costs maybe $50 dockside l.a., tops. and dumb-asses like you pay $400 for it. utterly STOOOOPID. It's fair to say that aluminum bikes are proven by now, too. Some prefer the steel ride and some prefer stiff aluminum.

That's why y'all can get by with plastic bikes. actually, /you/ ride plastic materials chalo - steel and aluminum are both ductile and thus plastically deform. but you're just too freakin' dumb to learn to use the correct terminology. |
