Campagnolo® Campagnolo Super Record Ultra-Torque 11-Speed Chainset

Shifting to the “highest quality”; the new chainrings have 8 pins to lift the chain and 2 to lower it. This
re-designed system makes shifting from one chainring to the other extremely fast and efficient.

CULT bearing technology guarantees a smooth and efficient pedalling action and a long lasting performance.

For those who only want the best and look for unique and exclusive components, this crank set with titanium fixing
bolts is the ultimate.

Technology

Ultra-Torque

Lightness, rigidity, simplified assembly and maintenance: ultra-torque. This is campagnolo’s answer in the
integrated crankset sector. After more than 10 years since its introduction the ultra-torque system, it is still
considered, the best performing crank-set spindle in terms of stiffness, low weight and efficiency of power
transmission.

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.

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.

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.

MPS Micro Precision Shifting System

Campagnolo is constantly focused on the performance of its groupsets for all its ranges, from Super Record to Ekar.
Its Micro Precision Shifting (M.P.S.) System fully refl ects this 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 persistence of the
engineers at our Campy Tech Lab who expect the maximum performance from all of Campagnolo’s products. The result is
amazing and now moving from one chainring to another, even under load, will no longer be a problem!

Optimised design of the up-shift and down-shift zones and of the profile of the teeth – enables fast and precise
shifting in all types of conditions.

CULT

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.
