P1s Pedals - side view



One year after PowerTap introduced the $1,199 P1 power meter pedals with individual, dual-leg measurements they have now brought the price down substantially with a new a single-sided version, the P1S. This is a trend that nearly every other dual-sided power meter brand has followed. This is likely because not everyone is quite so concerned with their exact left-to-right power balance and otherwise prefer simplicity and a price that’s typically around half that of a dual-sided design.

The $699 P1S features a gauged left pedal and non-gauged right, and like other unilateral power meters doubles the value of the single side to get total power. Because the right pedal still utilizes the same body design as the left, it can be upgraded down the road if a customer decides they want dual-sided power.

P1s pedals

The P1S uses the same design as the P1 dual-sided power meter, but is only gauged on the left side. This cuts the price in half compared to the P1.

One of the advantages the PowerTap P1 and P1S pedals offer over other pedal-based power meters is that the entire design is contained within the pedal body and doesn’t require transceiver pods that complicate installation and require a very specific torque value. They also feature dual band ANT+ and Bluetooth SMART for compatibility with nearly all head units and smart devices as well as over the air firmware updates. Weight is claimed to be about 8 grams lighter than the P1, coming in at 390 grams.

Being able to view pedaling metrics in real time can be an important tool in improving efficiency.

For those using the dual-sided P1 power meter pedals, PowerTap has launched a new tool called Advanced Pedal Metrics in their iOS Mobile App that gives a new perspective on bio-mechanics as it relates to how a cyclist moves their cranks and propels themselves down the road. The app will provide easy to understand visual data for not just pedal balance but also vector force, heat map and polar plot. These tools provide a better understanding of where power is being generated and how efficiently it’s delivered to the pedals. It can also provide instant feedback on how position or equipment changes may affect how one pedals their bicycle.

An iPhone can provide all the data one might need to get a clear picture of how power is applied to the pedals.
