Campagnolo Super Record 12-Speed Chainset With Stages Power Meter

The best chainset now has the best powermeter, Super Record 12x2 Speed crankset paired with a Stages Powermeter.

Campagnolo Super Record Chainset

The new Super Record 12x2 Speed crankset: an intense concentration of innovation that results in the greatest possible stiffness and precision in derailing, whilst providing a dedicated aerodynamic "super design".

The new carbon fibre Super Record 12x2 Speed crankset has been made lighter on the inside through Campagnolo Hollow Technology, which uses the Ultra-Torque bracket system with a titanium axle to transfer all of the force the athlete applies to the pedal to the drivetrain. The new Super Record™ 12x2 Speed crankset can be installed on any type of frame, whether or not it is being used with disc brakes because it optimises the chain line on the frame with a rear hub flange measuring 130, 135 or 142 millimetres, without affecting the Q factor, which remains constant at 145.5 millimetres thanks to the new hand crank design.

The use of ceramic Cult bearings leads to obtaining the smooth ride that the Campagnolo brand is known for. The innovative design of the outer chainring ensures faster, quieter derailing owing to the contoured pin. The symmetrical design of the inner chainring teeth allows improved stability with chain crossovers. The double wheel sizing standards (112 and 145 millimetres) combined with the eight fixing screws, optimises weight and stiffness through the increased use of carbon fibre.

The varying number of pins for each of the three chainring combinations (34/50, 36/52, 39/53) facilitates upshifting due to the optimised free strokes associated with each combination. The special drains on the inside of the outer chainrings optimise performance when downshifting in dead spots.

X.P.S.S. Extreme Performance Shifting System

X.P.S.S. is the embodiment of a project conceived with a very specific objective: to give the new Campagnolo 12-speed groupsets the best possible derailing performance. And the Campy Tech Lab has hit the mark once again.

The ascent and descent zones on the chainrings have been designed down to the smallest detail, using mathematical simulation programmes that reproduce the potential movements of the chain on the chainrings and draw the ideal angles of these. Repeated tests in the laboratory have enabled the speed and precision of derailings to be optimised. The profile of the chainring teeth has also been revised in order to render the action of these even more effective, and to ensure that they are perfectly in tune with the 12 Speed chain and the new front derailleur. All of these improvements enable a 25% increase in derailing under load and and a 20% the fluidity of shifting.

Indeed, the secret of this amazing result is the perfect combination and integration of all the components of the drivetrain: each of these is designed to work and function perfectly with the others - this is what enables you to enjoy the extraordinary performance that the new X.P.S.S. system offers.

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.

Stages Powermeter

Active Temperature Compensation as standard equipment

Consistency of measurement is the most important feature of a power meter. Stages Power was the first meter to make temperature compensation an automatic process ensuring accurate readings no matter the environmental conditions. ATC is the key reason a rider can trust data from Stages Power in all conditions.

Individual meter calibration for the most accurate results

Each Stages Power meter is calibrated individually to ensure a +/- 1,5% accuracy level, which is an industry best for non-scientific power meters.
