Pedal-based power isn’t a new thing but rarely has it come in so accessible a package as with the P1s.
The P1s are powered by a single AAA battery in each pedal, good for 60hrs riding time according to PowerTap, and installation is as simple as attaching the pedals using an 8mm allen key. There are no special tools or complicated torque ranges to achieve, just mount the pedals and go.
Those pedals transmit data gathered from eight strain gauges (in each) via ANT+ or Bluetooth Smart, meaning you can use the head unit of your choice. They’ll also analyse your pedal stroke, helping you to figure out where you put the power down, or help you boost your pedalling efficiency. That latter capability comes thanks to the innovative ‘Multipole Ring’ sensor, which measures application of force through each pedal stroke.
They’ll also show right/left balance, helpful for combating imbalances in your pedal stroke, and that data is provided on the go, meaning you can make adjustments as you ride with almost immediate feedback.
While they might be heavier than Garmin’s Vector 2s – 398g compared to 352g – they don’t require the finicky pods installation, as everything is house in the pedal itself. As a result, they’re bulkier as well but you’ll save £200 buying a set of these compared to the Vector 2.
Cleats are similar to LOOK’s Keo, but PowerTap supply their own with the pedals and don’t recommend the use of LOOK cleats with the P1s. This is because there are enough differences between the two to mean you might not find as secure a fit. There are two sets of cleats in the box, one with float and one without so there is a choice to fit your preference.
One other difference is stack height, with the P1s having a higher stack height than many standard pedals, meaning you’ll have to adjust seat height to compensate if you want to be millimetre perfect.
Overall though, the price combined with the quality of the product is sure to find many admirers. Plus the simplicity of installation makes the P1s the best choice around for anyone who wants to swap their power measurement between bikes. Especially anyone who can’t afford a power meter for every bike they own.
