I am confused, a Campy brifter, a Campy rear derailleur, why is there a Jtec adapter? Or, is that a cassette with Shimano/Sram sprocket spacing?
On my rando bike I am using a Campy 10 speed brifter for the rear with a Shimano XT derailleur and 8 speed Sram cassette. The cable pull per shift with a Campy 10 speed is almost identical to a Shimano 8 speed system, thus no Jtec adapter needed.
