What is really great is how the average speeds have hardly changed in 20 years despite the much touted advancements in materials. There is a slight bump during the Armstrong era, but in the end, the tactics make or break the race for the teams.

Thanks for the post. I've always looked for something like this. It would be even better if they put statisitics along with the photos. Tour distance, elevation, speed, etc.

Regarding speeds of the Tour, this is a chart of ave speeds and distance since 1960. Only a 2mph increase over 52yrs. Whats really interesting is as the distance goes up/down, the speed is directly inverse. And the distance has gotten shorter over time. So is the speed really 2mph faster??

Interesting how long single speeds were used and how it wasn't and instant switch to multi-speeds.
Actually it was dual-speeds for quite a while (until Tullio Campagnolo was bummed about losing his race on the Croce D'Aune Pass in the Gran Premio della Vittoria </SPAN sab="1149">because of the "shifting" problems he had, and started inventing shifting systems): There was a cog on either side of the hub, and to "shift" you'd open the wing nut, remove the rear wheel, flip it around, and reinstall...

Yeah, that's quite interesting. Once we figure in better roads, better nutrition, better training methods and consequently riders that are presumably quite a bit stronger, one wonders whether there's any effect at all left of the improved equipment. Certainly improved multi-gear shifting must have helped a bit, but the rest? Maybe reduced weight to some degree, but that's probably where it ends. What is entirely clear is that the effect of "frame stiffness" is zero...
