There are other points about Campy versus Shimano indexed drivetrains that deserve mention:

1. Campy rear setups seem to be more sensitive to cable adjustment for proper indexing. Certainly doable, but might need a rear shifter cable tweak more often than Shimano. The prolific Shimano RD’s of any quality level are easy to adjust and stay in adjustment longer thanks to that Centeron upper RD pulley, judging from the many donated bikes I’ve rebuilt for Bike Works in Seattle over the last five years.

2. Campy front shifting, however, is just the opposite, since their better brifters are basically a ratcheted variation of friction shifting. I’ve successfully used Suntour FD’s in a Campy setup, but slightly prefer the Campy Racing T FD’s. Whereas Shimano brifters require matching road FD’s and careful initial adjustment for the indexed front shifts. .

Like to think of my Sachs New Success shifting as the “best of both worlds”, with easy-to-set up Sachs RDs that have a floating upper pulley like Shimano’s and Sachs Ergo shifters (Campy Ergo with a different rear ratchet spacing, same parts used in rebuilds); 8-speed only, but I’m fine with that. No longer made, so I’ve got a collection.
