Campagnolo uses the best and most powerful motors. The motors used in EPSTM components ensure precise shifting even under strain and deliver the speediest shifting available with no loss in performance over time. HIGH TORQUE, HIGH DRIVE RATIO MOTORS Campagnolo has used the world's best electric motors for this application. These units ensure effective shifting even under strain, deliver the same performance time after time and make extremely fast, precise shifts possible. POSITION SENSOR With the Magnetic Hall Sensor Resolver , the front derailleur always moves the chain automatically into the ideal position for the selected sprocket/chainring. FRONT DERAILLEUR BODY IN MONOLITHIC CARBON POWDER TECHNOPOLYMER For maximum lightness and superlative stiffness. NEW INTERNAL AND EXTERNAL DERAILLER CAGE DESIGN WITH STEEL CONSTRUCTION A design optimised for the EPS drivetrain for maximised lightness and stiffness. Extreme derailing speed and precision even under strain. 100% WATERPROOF All the components of the front derailleur are built to operate in any weather conditions in compliance with the IP67 standard. CSD Chain Security Device The new CSD chain security device achieves extremely high stiffness levels, in addition to offering regulation that is completely independent from that of the derailleur. Compatible with all the braze-on derailleurs from the Campagnolo range. DERAILLEUR CLIP CLAMP Allows perfect interfacing with the Campagnolo braze-on derailleur, guaranteeing maxi High torque, high drive motors made in Switzerland for the best in precision shifting reliability Derailleur body in monolithic carbon powder polymer Steel derailleur plates with chrome-nickel treatment for durability 100% waterproof, meets stringent IPx7 standards Ride Setting allows returning home in the inner chanring should battery power fall
