RECORD crankset : One more weapon to win the battle. The Record crankset has been designed to transfer all the power of the cyclist to the drive wheel: maximum torsional rigidity of the system, the best "U" and "Q" factors of the category and all-carbon unidirectional cranksets. But the real surprise comes when the front derailleur is first operated: the special design of the XPSS chain ring up and down zones ensures a very precise, fast and delay-free shifting operation. Shifting the chain with the front derailleur is no longer a problem, even under extreme application conditions. USB ULTRA SMOOTH BEARINGS. Absolutely smooth surfaces and low friction to reduce energy loss as much as possible are the most interesting features. Add to that the reduced weight and corrosion resistance and you'll understand why USB is the best of the best for you. All your power is transferred to the road without loss. Campagnolo has always been respected for the extreme smoothness and reliability of its hubs. These characteristics are due to the fact that all the projects are developed in the Campy Tech Lab department and that almost manic care is given to every detail. The hubs with USB (Ultra Smooth Bearings) ceramic bearings further increase the smoothness of the wheels and reduce weight and maintenance. Comparative tests have shown that USB bearings are 50% smoother than standard bearings. An increase in your competition performance or even a ride with your friends is now made easier. The USB - Ultra Smooth Bearings - technology is used for the Record cranksets and for the new Shamal Ultra wheels. ULTRA-TORQUE. Campagnolo has ensured that the two halves of the bottom bracket axle are inseparably connected to the respective crank arms. This new development has made it possible to significantly reduce lateral protrusion from the frame at axle height, thus preventing unwanted contact with the ankle when pedaling. Their assembly is extremely simple, a single oversize screw is used to firmly connect the two halves of the axle to each other. In terms of the effectiveness of the torque transmission, this system can stand up to comparison with a one-piece axle. In addition, despite the narrow side profile, we have managed to place the bearings outside the bottom bracket housing, so that the axle, which has a larger diameter, becomes stiffer thanks to the increased support width. We were able to achieve these characteristics by using the Ultra-Torque, which is based on the Hirth spur gear, an ingenious mechanical system resulting from many years of experience in engine construction in the field of couplings for rotary axles and motor shafts. This is basically a coupling connection with self-centering and self-aligning spur teeth, which is located in the centre of the inner bearing axle where the ends of the axle halves firmly connected to the crank arms touch each other.
