Wow. Fantastically informative, thank you. Bikeforums.net leaves everything else for dead! Titan bars eh? They're certainly narrow by today's standards. I don't have the stem sadly. Someone had turfed it and replaced it with a modern MTB stem before chucking the whoole thing in the dump. It did come with a set of NR derailleurs which I've recycled onto other ppet bikes. It also had one original changer - a big wide circumference thing cast out of steel I think.
