I too would love an ultra low tech group. 6 spd, friction, etc. I bought one of the last US made low end Cannondale road bikes back in the 80's. An SR400 I believe. It had the last of the Shimano 105 non indexed setups that were mounted to brazons on the down tube. I think that Dura Ace was already indexed at that time. Very clean and worked flawlessly.
