Yep. At the time the trials were held it appears they were extremely influential, at least within the French industry. And it could be argued that the ending of the trials was equally influential as in many respects including the aforementioned cranks and brakes the modern engineers all the lessons learnt were apparently forgotten as even with modern materials and manufacturing processes those modern engineers are manifestly incapable of significantly bettering those products of decades earlier. Will a set of modern Campagnolo Record crankarms in CFRP really do anything functionally better than their half century old lighter production aluminum ancestors? Will a heavier pair of modern dual pivot brakes actually stop a bike unambiguously better than those ancient Herse cantis?

I doubt it. Which is both mindboggling and a pretty serious indictment of current bicycle component engineers' real competence. Maybe engineers just aren't properly empirically tested and measured today as they were then.

> Your logic escapes me. The last Traials were held in 1949. When the tri als were being held, and several years after, components like the TA cyclot ourist rings and Stronglight 49D cranks were made that were as light as muc h modern carbon stuff. So it appears the Trials had MAJOR influence on the
   componets being made when they were being held. Do they have influence to day? Of course not. Nearly everyone who participated in the last Trials i n 1949 is now dead, and few people in France and almost no one anywhere els e has ever heard of the Technical Trials. Until Jan chronicled them, few p eople even on the CR list had heard of them. Hard to be influenced by hist ory of which one is ignorant.
