I've never had Campagnolo on any bike. My first bike had Shimano Tiagra with the thumb lever on the inside of the hood....much like Campy's Ergopower shifters. I found it very difficult to shift to an easier gear from the drops. How is this not an issue with Campy? I can't imagine that so many pros would be using Campagnolo if that was the case. Someone please school me on the Campy drivetrain.
