The new HPPM (high precision power measurement) power meter from Campagnolo features 16 sensors and 1 gyroscope. Developed specifically for road bikes, Campagnolo’s goal with HPPM is to provide the most precise data possible to support the most demanding performances.
The Campagnolo HPPM power meter falls into the family of ‘spider-based’ power meters, i.e. with 16 sensors positioned in the spokes of the crankset to detect torque values, expressed in Newton meters.
Campagnolo adds that the power data is obtained from a real-time crossing of torque value with the angular velocity provided by the integrated gyroscope. With high frequency data sampling, the 16 strain gauges produce multiple readings, which, when combined with a specific algorithm, claim to guarantee a high accuracy of +/- 1%.
‘The angular velocity and torque signals are in fact measured every five milliseconds. A very high frequency equal to 200 hertz, which gives the clearest possible reading of the data.’
Equipped with an Ultra-Torque titanium axle and unidirectional carbon fibre cranks (available in 170, 172.5 and 175mm), the crankset with HPPM Power Meter has three chainring options: 45-29, 48-32, 50-34.
The new My Campy 3.0 app allows the system calibration in just a few steps and shows the battery charge status with a modern and intuitive interface. A single charge is claimed to last for over a month and charging time is just under four hours.
