Hokey Smokes! That's mixing three different brands/specs maybe!!! And it worked? Do you know any exorcists? Something unholy happening there...

Back in the day, when all they made was shifters, SRAM built both Suntour- and Shimano-compatible shifters. Shimano tried to "convince" customers to not buy SRAM by pricing components higher if bought without shifters, or not promising timely shipping. SRAM sued Shimano in the US and won, so when SRAM asked Suntour for samples to design Suntour-compatible levers, Suntour said sure-howdy. That may have been when SRAM's only product was the Grip-Shift, don't remember them having barcons at the time. Not sure whether they were making Campy-compatible in those days as well. I'd guess that once everybody stopped specing Suntour, SRAM cut way back on Suntour-compatible production.

So I don't know if SRAM ever offered Campy-compatible barcons, but either way, very cool/lucky for you that the mixture works on your Allez Pro.
