Cool, thanks,
SpeedofLite , I've had some of that DA group sitting in a box since last year waiting to be built up on an early '90s Trek 5900.
I was surprised to see the article mention backward compatibility with 6 and 7 speed STI. I must have misread other specs that cast some doubt on backward compatibility. I've been using mostly 8-speed Ultegra front and rear derailleurs because I was under the impression they retained more backward compatibility.
Now I'm encouraged to finish cleaning those DA 7402 bits and put 'em on a bike.
