Ok, call me an idiot, but I have never used Campy shifters before. I've only used SRAM and Shimano mountain groups and Shimano road groups. How do you shift with the little thumb lever? It seems like it would ne harder to shift in the drops. I'm thinking of a Record (or Super Record?) group for my next bike and would like to know how they work. Does anyone have any links with pictures, etc...? I've done quite a bit of research on the differences between Shimano, Campy, and SRAM but I've never run across anything explaining how they work. I'd like to go with something different for my next bike and I think Campy will be it. Thanks for the help.
