Campagnolo Super Record WRL SPowermeter crankset:

The new Super Record Wireless 12x2 crankset with power meter: Campagnolo’s iconic design in a matt black finish. The Super Record Wireless crankset with power meter retains the hollow, lightweight structure and uses the Ultra-Torque locking system with a steel bottom bracket axle to transfer all the force the rider applies to the pedals to the drivetrain.

The force applied to the pedals is measured via a gyroscope, which constantly detects its own position, and via 16 strain gauges. Power measurement is extremely precise, with a tolerance of +/-1 per cent. Thanks to the new Mycampy 3.0 app, you can easily check the battery charge level at any time. A single charge lasts for one month’s use.
The new Super Record Wireless 12x2 crankset with power meter can be charged very easily using the same charging cable as the other components in the groupset. The use of USB ceramic bearings ensures the now familiar smoothness of operation that has become Campagnolo’s trademark.

The ULTRA-TORQUE system completes the specification and ensures that all your power is converted into exceptional performance. Instant and unstoppable acceleration thanks to a titanium axle and lightweight carbon fibre cranks. The chainring has been redesigned for uncompromising efficiency. Every watt of your power is transferred to the road.

Campagnolo HPPM:

High Precision Power Measurement. The power meter crank of the Super Record Wireless series embodies all of Campagnolo’s technical expertise. Reliable measurement results are ensured by high-frequency data acquisition every 5 ms / 200 Hz via 16 strain gauges arranged in a diamond pattern, which record the torque in Nm, as well as an integrated gyroscope that determines the angular velocity in real time. A special algorithm combines the numerous measurement values to achieve an incredibly high level of precision of +/- 1 per cent. A lithium-polymer battery powers the power meter positioned in the crank spider; it uses the same magnetic connector for charging as the other Super Record Wireless electronic components. A full charge takes less than 4 hours and is sufficient for over a month’s use. The My Campy 3.0 app for Android and iOS not only allows you to check the charge status; the app also enables you to calibrate the spider-based power meter system in just a few steps.

Campagnolo Super Record crank axle

The tried-and-tested system with Hirt threading ensures an extremely stable connection between the two steel axle halves. As the connection point of the axle lies exactly in the centre – and thus in the part of the axle construction subjected to the highest stress – the forces exerted are absorbed optimally. The bolted connection, with its increased axle material, reliably prevents twisting, even with stronger and/or heavier riders.

Campagnolo WRL Chainrings

The exclusive design of the zones for shifting the chain up and down. The special profiles of the teeth and the areas for shifting the chain up and down enable precise and rapid shifting of the front derailleur in all conditions. This system allows for effective, smooth and rapid shifting between the chainrings. The chainring mounting system, in which the chainring bolts are screwed directly into the small chainring, enables quick installation of the individual chainrings. It is lighter and makes this connection stable, rigid and secure. The chainrings are hard-anodised for improved wear resistance and resistance to salt corrosion.
