Nut in zis contry! The German TOUR magazine did a very interesting test a few years ago. Read my translation on Google Groups. Bottom line- Going from the noodliest ultralight steel frame to the stiffest aluminum frame had the same effect as changing your tire pressure 10 psi. They concluded this by measuring impact on a rider with sensors. http://groups.google.com/groups?hl=en&lr=&threadm=3799C7EE.68D5F607%40HotPOP .com&rnum=6&prev=/groups%3Fq%3Dgerman%2Bmagazine%2Btour%2Bperkins%2Bgroup:re c.bicycles.tech%26hl%3Den%26lr%3D%26scoring%3Dd%26selm%3D3799C7EE.68D5F607%2 540HotPOP.com%26rnum%3D6
