PowerTap P1 Pedals FAQ

General

Are the pedals single- or dual-sided?

You have the option of either. The P1 pedals are two separate power meters, which talk to each other. The data is collected by the master pedal (Left), then sent to your head unit. The P1 pedals allow the user to receive detailed left/right leg balance.

The P1S pedals are a left-only system. They measure power from the left leg only and double it in order to compute your total power.

Do the P1 pedals have a weight limit?

No weight limit.

What is the warranty on the PowerTap P1 pedals?

The electronics have a 2 year global warranty. The bearings, skid, and plate are all wearable items and do not have a warranty.

How does the stack height compare to other pedals?

The P1 pedal’s stack height is 14 mm, which is about 3-5 mm greater than some of the other popular pedal systems on the market.

What is the P1 Pedal body made from?

The P1 pedal features a forged aluminum pedal body, which is standard for most pedals.

Does the P1 come with cleats?

Yes, the P1 comes with proprietary 6 degree float PowerTap cleats and hardware. You can also buy a 0 degree float cleat option as an extra accessory.

What type of cleats do the P1 Pedals use?

The P1 pedals use proprietary, 3-bolt keo-style cleats. 0 degree and 6 degree float options are available.

Do the P1 Pedals support oval/non-round chainrings?

Non-round rings are supported perfectly with the P1. The P1 takesĀ 40 individual angular velocity measurements and subsequently 40 power measurements per pedal stroke. Any acceleration/deceleration within a pedal stroke would be measured. Other systems assume constant angular velocity, which typically reports higher power when using non-round rings.

Can I adjust the release tension on the pedal?

Yes, you will need a 2. 5mm hex wrench to adjust. Release tension range is 6-20 Nm.

 

Installation

How much torque do I need to use when installing the P1 pedals?

We recommend you follow the recommended torque guidelines from your crank manufacturer. Pedal installation torque generally ranges from 300-350 inch lbs. (35-40 Nm).

Do I have to set the installation angle on the P1 pedals?

No, you do not need to set the installation on the P1 pedals. The P1 pedals learn the position of the axle relative to the crank arm after a few pedal strokes.

Do I need to set my crank length on my bicycle computer?

Yes, for maximum accuracy, you should always set the proper crank length on the bicycle computer that you have paired with your P1 pedals.

How do I set my crank length on the Garmin Edge 1000?

As of the writing of this answer, the Edge 1000 is missing the crank length setting under the sensor detail section. We believe this is a bug in the firmware and are working on a solution. The default setting in the Edge 1000 is 172.5 mm. If your crank length happens to be 172.5 mm, then you are good to go. If your crank length is not 172.5 mm, your power will be off by a percentage based on the difference in crank length. For any issues related to future firmware functionality, we recommend contacting Garmin Support.

How do I set my crank length on the Garmin Forerunner 920XT?

To set the crank length for your P1 pedals on a Garmin Forerunner 920XT, you will need to have the 2.5 version of firmware. After version 2.5 Garmin released three other firmware versions: 3.3, 4.2 and 5.2. The option to set crank length in versions 4.2 and 5.2 does not appear for pedal-based power meters other than the Garmin Vector pedals. If your crank length happens to be 172.5 mm, then you are good to go. If your crank length is not 172.5 mm, your power will be off by a percentage based on the difference in crank length. For any issues related to future firmware functionality, we recommend contacting Garmin Support.

 

Battery

What type of battery does the P1 use?

Each pedal uses one AAA battery. Two AAA lithium batteries are included with the P1 pedals. For best performance, we recommend using lithium batteries. Compared to alkaline batteries, lithium batteries are more powerful and regulate heat better. Rechargeable batteries are not recommended.

 

Calibration

Can I manually zero (calibrate) or auto zero the P1 pedals?

Yes, we recommend that you perform a manual zero before each ride. The pedals also have active temperature compensation where sensors within the pedal monitor the temperature and adjust the offset accordingly.
