Using your Campagnolo Chorus Hydraulic Brake/Shift Lever is easy. For shifting gears, use the Ultra - Shift function to quickly change multiple gears with one motion. When braking, squeeze the aluminum lever, and you can adjust the reach to fit your hand size. Make sure to use mineral oil as the hydraulic fluid. When it comes to maintenance, regularly check the brake pads. If they're semi - metallic and worn out, replace them. Keep the caliper clean from dirt and debris. And if you plan to use different front derailleurs or shifters, ensure they're compatible with Campy Centaur/Potenza/Chorus/Record/Super Record 2015+ models.
