Campagnolo Ultra Bearing Set - QCK-TECH | USB (Ceramic)

Ultra Package – Elevate Your Components The ultimate further development of the Super Record 13 series. This upgrade not only raises the aesthetic value of the groupset to a new level, the components are also set to break all boundaries in terms of performance. Italian design meets aerospace-grade materials. A masterpiece of mechatronics, manufactured in Vicenza, developed for the most demanding cyclists looking for extreme performance, maximum lightness and incomparable style. Campagnolo Ultra ceramic bearings Not visible, but no less important in Campagnolo's Ultra portfolio: the bearings for the crankset. These are tailored to the QCK-TECH bottom brackets of the Super Record 13 series and use ceramic balls made of silicon nitride which meet the requirements of international aerospace standards. This means not only minimal inclusions and metal particles, but also optimum roundness, maximum precision and excellent surface integrity. To further improve the technical properties and reduce noise as well as friction between the balls, Campagnolo has also revised the inner cage made of resin. In addition, a double sealing system is used. While the internal sealing unit protects the bearings in the vicinity of the inner and outer ring, the external sealing system positioned between the outer ring and the bottom bracket axle ensures long-term cleanliness and a friction-free rolling behavior of the balls. Invisible smoothness, noticeable performance. Features of the Ultra ball bearings: ceramic balls from aerospace grade silicon nitride high-performance cage made of resin with double seal protection system less friction, longer service life, smoother pedaling overall weight reduction for the bottom bracket (example BSA: complete only 49 grams) only suitable for QCK-TECH bottom bracket cups PLAY YOUTUBE VIDEO By clicking on "Accept & Play", you agree that Youtube sets cookies on your end device and that data is transmitted to Youtube.

In order to offer ambitious road bike enthusiasts the best of the best, the Campy Tech Lab™ has devoted almost manic attention to every detail in the development of the USB™ ceramic bearings. Absolutely smooth surfaces and minimal friction are required to reduce energy loss as much as possible and enable virtually loss-free transmission of power to the road. In the case of USB™ deep groove ball bearings, maximum corrosion resistance and reduced weight are added to further increase competition performance. Comparative tests show that bearings with USB™ technology run 50 % smoother than standard bearings. Scope of supply: 2 ceramic hybrid bearings
