Campagnolo Super Record 12x Front Mech

The Super Record 12X2 Speed mechanical front derailleur: lightness, design, fluidity and effectiveness. The Super Record 12X2 Speed mechanical front derailleur introduces many new techniques, starting with the leverage system which is designed to speed up derailment. Less effort is required to shift, this is thanks to the split front connecting rod, which prevents contact with the travel limit screw. Whilst the shape of the inner cage plate is engineered to guarantee maximum readiness for upshifting, the external monolith body in carbon fibre has been shaped to enhance the efficiency of the chain movement when climbing and the readiness and fluidity in descent. The aesthetic impact of the front mech has been kept in line with the rest of the Super Record groupset by the use of unidirectional carbon fibre and titanium stop screws. Micro-adjustments to the front derailleur position, which can be adjusted by the ergo controls, help to prevent any contact with the chain, even at maximum crossover. The new Super Record 12X2 Speed front derailleur allows the use of tyres up to 32mm thanks to the design of the upper connector rod and the double fixing position of the control cable.

Campagnolo Chorus 12x Rear Mech

New 12x Chorus rear derailleur for use with the disc or rim brake groupsets. The new Chorus rear derailleur benefits from the same technology and design of top-end Campagnolo products, incorporating the sophistication and performances of the 12-speed Super Record and Record. With just a few changes in the materials used for its construction, like the external plate and derailleur cage in aluminum, the Chorus version produces exactly the same performance as the two more expensive groupsets with the addition of just a few extra grams. Chorus brings with it the same technology as the next level up, like the new optimized trajectory on bigger cassettes and fantastic 3D EMBRACE technology. The latest evolution in Embrace technology not only keeps the rear derailleur vertically aligned in the perfect position for each sprocket, it now makes the upper pulley wheel advance perfectly in the direction the bike is advancing. 3D EMBRACE technology and 12-teeth pulley wheels makes this rear derailleur suitable for all cassettes as the distance stays optimum on each individual sprocket, regardless of the cassette selected. Technologies 3D Embrace Technology: Movement of the rear derailleur is designed to make the chain embrace more teeth per sprocket to guarantee maximum traction. Optimised trajectory: Movement of the rear derailleur means that the upper pulley wheel on the cage is always constantly close to the sprocket in use. 12-tooth pulley wheels: Perfect for cassettes that have a wide range of teeth. Optimised return spring: This guarantees constant chain tension regardless of road vibration.
