What rear derailleur are you using with the Campagnolo shifters? 8 or 9 speed?
Didn't the bicycle division get acquired by SRAM?I think of Sachs as a company primarily involved in small engine related stuff. Now that you mention it I believe that I have seen Sachs branded clutches for 5.9 L Cummins engines. I wish they had not abandoned the bike parts area. Even though made by several different companies, the Sachs branded parts were very high quality.
