CAMPAGNOLO Super Record S Wireless crankset | 2-speed
With the Campagnolo Super Record S Wireless components, the Italians offer you a special version of their top component groupset with a matt black finish and a better price-performance ratio. In technical terms, the Super Record S components are on a par with the top groupset and have the same technologies and performance. Only the materials used have been changed in some details, which makes the Super Record S groupset slightly heavier than the Super Record Wireless.
Without question, the crankset of the Super Record S Wireless groupset is something to behold. The combination of matt aluminum chainrings and the carbon crankarms with their iconic design and matt UD carbon finish ensures this. Four different chainring combinations are available which, together with the new cassettes, offer a wide range of gear ratios for every route profile. When developing the drivetrain system, the focus was on smooth and precise running of the chain, especially with a larger diagonal chain guide, in order to make optimum use of all 24 gears. For the crankshaft system, Campagnolo relies on its proprietary UltraTorque technology, in which the two-piece steel axle is permanently connected to the crank arms. The axle halves are equipped with Hirth splines at the contact point and are fixed in place by means of a single oversize bolt when the crank is assembled. This special form of toothing is used wherever precise positioning and repeat accuracy are required. This design also significantly reduces the amount of space required at the side of the axle, which prevents unwanted contact with the ankle when pedaling. The ball bearings pressed onto the shaft ensure maximum smoothness and, in combination with ProTech bearing shells, offer unique protection against harmful ingress of water and dirt. Thanks to the variety of Campagnolo ProTech bearing shells, the Super Record Wireless crank is compatible with all current bottom bracket standards. All components of the electronic groupset are manufactured in Italy and stand for a high degree of perfection and reliability.
