I had Campy Chorus on my go-fast bike I sold a few years ago, and it is absolutely the best gruppo I have ever used. Would use it again in a minute if given half a chance. Easy shifting, fit my hands well, a huge improvement for me over Shimano Ultegra, which I had before.

I have bar-end shifters now due to the V-brakes on my Bike Friday (which is set up as a touring bike), and I like them fine, but I do miss my Campy. It was like "butta".
