Description of Campagnolo H11 Ultra-Torque Carbon Crankset 11-speed

As the geometries and spacing found on disc brake frames differs a good deal with respect to their traditional rim brake predecessors the design of the transmission and chainline must take these differences into account to ensure optimum performance. Campagnolo engineers have developed the H11 crankset to match perfectly with Super Record, Record and Chorus transmissions. This ensures shifting is as crisp, clean and precise as on any other groupset with rim brakes. This crankset design provides excellent precision for 142 mm rear spacing and does so without altering the Q factor.

The maximum that you could ask for in performance and smoothness. The H11 crankset is an extraordinary concentration of technology and performance: extremely high overall stiffness, extraordinary lightness, fast and precise shifting.

Features and benefits of Campagnolo H11 Ultra-Torque


Ultra Torque™ technology
Pressure on the pedals is transmitted efficiently without any power loss.

Hollow cranks and spider arms with Ultra Hollow™ technology
Reduced weight of stress-free sections, improved crank set weight to stiffness ratio.

Double standardized bolt circle bolt circle diameter on all combinations
Maximum stiffness and lightness thanks to extension of the carbon fiber crank close to the chainrings with 112 mm for the small bolt circle diameter and 145 mm for the large one.

Technologies of Campagnolo H11 Ultra-Torque


Ultra Torque™

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, Campagnolo has 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.


X.P.S.S.™ (Extreme Performance Shifting System)

X.P.S.S.™ incorporates a project with a specific goal: giving Campagnolo's new 11-speed groupsets the best shifting performance possible. And the Campy Tech Lab™ has hit the mark once again. The new design of the chains up shifting and downshifting has been analysed to the smallest detail with mathematical functions to simulate possible movements of the chain on the chainrings and design optimal angles. Furthermore, repeated lab tests on the speed and precision of the shifting action have allowed Camapgnolo to complete the product's optimization.

Campagnolo has also reviewed the profile of the chainring teeth to enhance efficiency and compatibility with the 11-Speed chain and the cleverly-shaped derailleur to contribute to making the movement of the chain extremely quick, even under load.

Indeed the secret of this amazing result is a perfect combination and integration of all the drive train's components. Each one of them is designed to perfectly fit and work with the rest. This is the only way you will be able to enjoy the extraordinary performance of the new X.P.S.S.™ system.



Compatibility note:
To ensure the functionality of the mechanical drivetrains, Campagnolo recommends to avoid the use of older components at shifting groups from 2015 on. A distinctive marking, a squared letter as in picture 3, helps recognizing actual shifting components. The letters of the corresponding parts (right Ergopower and rear derailleur / left Ergopower, derailleur, cups and crankset) should match.

Note: Bottom bracket cups are not included.
