Description of Campagnolo Super Record Titanium Ultra-Torque Carbon Crankset 11-speed 52/36 - 2015
The maximum that you could ask for in performance and smoothness. The Super Record™ crankset is an extraordinary concentration of technology and performance: extremely high overall stiffness, extraordinary lightness, fast and precise shifting; the CULT™ system and the option with titanium axle, all this enhances even more the performance and uniqueness of this crankset.
Features & Benefits
Titanium axle and reverse thread titanium fixing bolt
Reduces the overall weight of the crankset by 40 grams.
Hollow cranks and spider arms with ULTRA-HOLLOW™ technology
Reduced weight of stress-free sections, improved crank set weight to stiffness ratio.
Pressure on the pedals is transmitted efficiently without any power loss.
Sophisticated mechanical features on the parts that move the chain up and down guarantee maximum efficiency during shifting. A further evolution of the chainrings used by Pro-Teams in 2014.
Differentiated number of pins depending on the chainring combination
Constantly optimum engagement of the chain. Maximum shifting efficiency.
The highest performing ceramic bearings combined with Cronitect steel make for a combination that is 9 times smoother, resistant to corrosion and extremely long lasting.
Double standardized bolt circle bolt circle diameter on all combinations
Maximum stiffness and lightness thanks to extension of the carbon fber crank close to the chainrings with 112 mm for the small bolt circle diameter and 145 mm for the large one.
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.
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.
Super Record bottom bracket cups are not included!
