I'm familar with these as I'm trying to help a "friend of a friend" re-hab a 90s 7 speed STI bike. His original 3X7 speed STI's are busted.

What I really wonder about is why they made this new offering incompatible with triple front? I mean, a lot of the old 7 speed STI bikes had triples. It was very common. Plus, a triple front shifter is double compatible - so you're not losing anything there - you still only have to manufacturer one type of front shifter.

Craziness.
