mmm food for thought on the Campag . I am re-building up a carbon Peugot Team line at the minute and trying to get the 9 spd 7700 DA bits I need to finish it. (Shifters/Derailleurs) , I have the 7400 DA 7 spd on the SLX Merckx but I'm concerned the 7410 DA 8spd is a bit too young for my 89 Cannondale 3.0 frame.
But i still like the 7800 10spd and the 6600 Ultegra on my training bike, Wife hates so many bikes and the old stuff even worse haha.
