Our CULT Technology (Ceramic Ultimate Level Technology) and a new Corrosion-Proof treatment exalt its strength and endurance. The use of unidirectional and multidirectional carbon fibre in the Ultra-Hollow structure gives the cranks rigidity and lightness. ESP (Enhanced Shifting Performance) technology ensures precision and speed when shifting. The outer chainring has been designed much more stiffer to give out more power transmission and both rings have a new surface treatment increasing wearing life.

Cult (Ceramic Ultimate Level Technology)
Today Campagnolo is evolving the ceramic ball bearing concept using CULT (Ceramic Ultimate Level Technology).We have combined the best ceramic ball bearings on the market with a stainless chromium steel with exceptional hardness called Cronitect. It's the result of 'Advanced by FAG' technology, Schaffer group, and it will be Campagnolo exclusivity for the next 3 years (for the cycling field). The thermochemical treatment of the surface layer ensures resistance to corrosion and wear. It also improves smoothness and grease is no longer required.

Cult technology is destined only for the top products: Super Record chainsets and the highest range wheels.

Ultra-Torque™
Lightness, rigidity, simplified assembly and maintenance: Ultra-Torque™.

This is Campagnolo®'s answer in the integrated crankset sector.

MORE ERGONOMIC
Campagnolo® found a way to permanently conjoin the semi-axles of the bottom bracket to the respective crankset arms. This redesign made it possible to considerably reduce the lateral dimensions at the axle level and prevent annoying contact with the ankles when turning the pedals.

EASIER
Assembly is simplistic: one single oversize bolt is enough to integrate the two semi-axles. With regard to torque transmission efficiency, this system is equally as effective as a single piece axle.

MORE RIGID
Furthermore, despite the narrow side profile, we have been able to position the bearings outside the bottom bracket shell, resulting in greater axle rigidity from the increased axle diameter. This breakthrough was obtained by using an ingenious mechanical system derived from many years' motoring experience in the rotation axle and engine shaft coupling sector: the Hirth joint.

In short , this is a joint with self-centring and self-aligning frontal teeth located in the middle of the bottom-bracket axle where the ends of the semi-axles, integrated with the crankset arms, come into contact.
