Campagnolo Power Meters

Connectivity, Compatibility and the MyCampy Ecosystem

Dual-band transmission - ANT+ and Bluetooth LE running simultaneously - means the power meter talks to virtually every modern head unit without you having to choose a protocol and hope. Garmin, Wahoo, Hammerhead, Polar, Bryton: all pair cleanly. Zwift and TrainerRoad pick it up just as readily for indoor sessions. If you've been running a Favero or Quarq unit previously, the head unit side of things will feel entirely familiar - no new hardware required.

The MyCampy 3.0 app is where the initial setup lives. It's not complicated: pair the unit via Bluetooth, run your zero-offset calibration, and you're done. Firmware updates push through the app too, so you're not hunting for cables or proprietary software on a laptop. The app also lets you check battery status and tweak basic settings. It's designed around the Super Record Wireless groupset, but the power data output itself is entirely standard - your head unit receives watts, cadence, and left/right balance figures in exactly the same format it would from any other unit on the market. No lock-in on the data side.

How the HPPM System Actually Works

The 16 strain gauges matter because more measurement points mean less chance of a torque spike skewing your numbers. They're arranged in a rhombus pattern across the spider, capturing the flex in the crank as you push through each pedal stroke. The integrated gyroscope handles angular velocity - tracking exactly how fast the crank is rotating at any given instant. Together, those two data streams are sampled every five milliseconds, which is how the system arrives at a genuine +/- 1% accuracy figure rather than a marketing approximation.

Being spider-based means total power is measured at the spider rather than at each pedal axle independently. Left/right balance is estimated from that total rather than calculated from two fully independent sensors. For most riders doing structured training or racing, that distinction rarely surfaces as a practical problem - the accuracy is there. Where it becomes relevant is if you have a clinically significant leg imbalance and your coach is working specifically on correcting it; in that case, a dual-sided pedal-based unit like those in the Shimano power meter range might offer more granular left/right data. For the vast majority of road riders, though, the HPPM system gives you everything you need.

Battery life is quoted at around a month of regular riding. In practice, cold January mornings in the Pennines or wet February rides through the Scottish Borders will nudge that down slightly - lithium-ion cells lose a little capacity in low temperatures. Keep an eye on the app's battery indicator heading into a big training block and top it up beforehand rather than relying on the claimed figure to the day.

Getting It Fitted and Keeping It Running Through a UK Winter

The power meter uses Campagnolo's Ultra-Torque bottom bracket interface. If you're currently running a non-Ultra-Torque setup, factor that into your plans before purchase - a bottom bracket swap may be needed. Installation itself is straightforward but worth doing carefully: the strain gauges need the crank seated correctly to read accurately, so use a proper torque wrench and follow Campagnolo's specified values. A Campagnolo-compatible tool set makes this considerably less stressful than improvising.

IP67 waterproofing means rain, puddle spray, and the general misery of a British autumn commute aren't going to cause problems. The electronics are sealed properly, not just splash-resistant in the loosest sense. Where you do need to pay attention is the magnetic USB charging port. Road salt and fine grit from B-road riding can collect around the contacts - give the port a quick wipe with a dry cloth before snapping the charger on. It takes ten seconds and prevents the kind of corrosion that would otherwise quietly degrade the connection over a winter.

The magnetic charging design itself is genuinely practical. The cable clicks into place positively, there's no fiddling with tiny ports in poor light, and a full charge from flat takes a couple of hours. Compared to coin-cell battery units - where you're hunting for a CR2032 at 7am before a winter ride - the rechargeable setup is a clear quality-of-life improvement. If you're also considering alternatives on the market, the SRAM power meter range uses a broadly similar rechargeable approach on their higher-end units, though the integration story differs.
