It paired up with German power meter experts Power2Max to develop the Powerbox crank-based power meter. With its comprehensive range of chainrings, chainsets and bottom brackets, a power meter is a natural extension of its product portfolio for FSA.

Calibration using any bike computer or the 4iiii app makes usability brilliant. Installation is very easy, as is switching between bikes. We also experienced no issues with regards to water ingress. Our testing found that it is sufficiently accurate and consistent to itself, meaning the Precision 3.0 is a useful training tool for those wanting to track their progress using power. The 4iiii Precision only measures left leg power, but you can easily adjust the scale factor on the 4iiii app to account for a known imbalance in your power output between your legs. Compatible with Shimano cranksets, the Precision 3.0 uses the same spec of power meter regardless of whether it’s fitted to a 105 crank (which we tested) or a Dura Ace model.

Since the new Wahoo design uses a stainless steel rim that mates with the cleat, we were impressed to find they were looking almost as good as new after our six month testing period. You don’t get pedalling dynamics data though, such as torque effectiveness or pedal smoothness, which can be found on Garmin and Favero models. Post-ride analysis on the Wahoo app includes left/right balance (with the dual sided version), average and max power, TSS, normalized power, power curve and time in zones – which covers most training needs. We were impressed by their accuracy too, although with the single caveat being that the pedals appear to ‘smooth’ slightly, meaning that peak sprinting power appears lower for shortest time durations. Incredibly easy to set up and use, the build quality is superb and there were no pairing issues either. Durable and super reliable, the Wahoo Powrlink Zero dual sided power meter pedals are a high-quality product for those who prefer the adjustability of the Speedplay cleat/pedal platform – and they’re fairly priced compared to the competition too.
