It's a Campy thing, you wouldn't understand.

Why I ride Campagnolo:
Quality of fit and finish is the best, always has been.
Functionality is excellent outside of the Syncros era, always has been.
Durability is unrivaled, always has been.
Aesthetics are excellent, always, and not exclusive to the top tier product.

Why I do not ride Shimano:
Shifter feel is too mishy-mashy. Not mechanical enough, doesn't tell my hand the thing has made a positive shift.
Shifter throws are too long, and hood ergos are really messed up.
Neon green grease.
Looks like crap.
Too common.
No real price advantage considering Shimano's short comings.

Why I don't ride SRAM:
Because I ride Campy!
