CAMPAGNOLO Record Rear Derailleur

Not only for Campagnolo, 12 is a lucky number. Many cultures even consider it to be a holy number, which stands for perfection and completeness. With the Record 12s™ 12-speed rear derailleur, the Italian manufacturer for high-end road bike components completes its extraordinary 12-speed groupset and brings Campagnolo road shifting systems even a little closer to perfection. Thanks to the high-end technologies used, e.g. the Ultra Shift™ geometry and the 3D Embrace Technology™, paired with high-quality materials like unidirectional carbon, aluminium and technopolymer, the Record 12s™ 12-speed rear derailleur allows for easy, fast and extremely precise gear shifts.The slightly revised 2020 model of the Campagnolo Super Record 12s™ rear derailleur is now also compatible with large 34 teeth sprockets. The special shape enables the rear mech to keep the chain closer to the cassette.This results in improved power transfer, increased traction, better chain/sprocket connection and higher durability of components that are subject to wear.12-tooth pulley wheels with bearings for extremely smooth running and low friction.3D Embrace Technology™: This technology keeps the rear derailleur vertically aligned in the perfect position for each sprocket and makes the upper pulley wheel advance perfectly in the direction the bike is advancing. In addition, it ensures a precise alignment to the selected chainrings and sprockets in relation to each other. Upper and lower derailleur body made of carbon fibre reinforced monolithic technopolymer for a low weight and high resistance. Outer derailleur cage made from carbon fibre for high stiffness, precise positioning and a low weight.
