The evolved design of the up-shift and down-shift zones and of the teeth profile enables fast, precise shifting in any conditions
Lightness, stiffness, and simplified assembly: ULTRA-TORQUE™.
Campagnolo constantly strives to achieve maximum performance from all its ranges of groupsets, from Super Record Wireless to Ekar™. The Micro Precision Shifting™ (M.P.S.™) System fully reflects this company philosophy: absolute precision, speed and a reduction of the distance covered by the chain when moving from one chainring to another. Mechanical work on the outer chainring is proof of the obsessive attention to detail and the perseverance of our Campy Tech Lab™ designers, who aim for maximum performance from all of Campagnolo’s products. The result is surprising and changing chainrings, even under load, is now no longer a problem! The evolved design of the up-shift and down-shift zones and of the teeth profile enables fast, precise shifting in any conditions.
Lightness, stiffness, and simplified assembly: ULTRA-TORQUE™. Campagnolo® has permanently conjoined the semi-axles of the bottom bracket to the respective crankset arms. This redesign has made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals. Assembly couldn’t be simpler: a single oversize bolt is enough to integrate the two semi-axles. This breakthrough was achieved thanks to an ingenious mechanical system derived from many years’ experience in the coupling and rotation axle sector: the Hirth joint. This is basically a joint with self-centering, self-aligning frontal teeth positioned in the middle of the bottom-bracket axle where the ends of the semi-axles, integrated with the crankset arms, come into contact. Where torque transmission is concerned, this system is equally as effective as a single-piece axle, which therefore guarantees unrivalled power transmission.
