Anybody have any feedback/experience with the new Shimano indexed shifting system?

> Anybody have any feedback/experience with the new Shimano indexed > shifting system? I stopped by the Shimano booth at the Coors Classic Expo at North Boulder Park. They had a bike set up on a turbo trainer with the new Dura Ace for people to try out. Since I rode to the race and had my cleats with me I decided to try it out. Actually I was able to stand up and sprint as hard as I could while a friend shifted the gears and it always shifted. I was amazed. This derailier was shifting better than my Super Record while I was doing things that would cause other derailiers to explode. I talked to the rep and he said that it works best with normal 6 speed Shimano 600 or Dura Ace freewheels and Sedisport chain. With a Suntour or Regina normal 6 speed it works about 80% as well. A friend of mine got a wheel in a race with a narrow 7 speed freewheel and it shifted about the same as a Campy Super Record. Personally I think that this is the way to go. The only problem is that you will never have an excuse for missing a shift. Mike Walpole
