I'm not entirely sure what you tested, but on my SR bike, there's an inner lever that switches gears and the thumb lever that changes gears the other way. On the other hand, my Ultegra bike has the inner lever, same as the Campy, but to cog up, you have to use both the inner lever and the brake lever. I guess I'm not sure what you're saying.

How does the MicroShift thing work?
