POWRLINK ZERO requires minimal cleaning and maintenance if dirt or grime collects.
-
Avoid using strong cleaning agents other than isopropyl alcohol as these may damage or reduce product lifespan.
-
Though additional grease is not required on any part after installation, optimal cleat longevity and performance is achieved through regular cleaning and lube, roughly every 200-300 mi (300-500 km). To properly service, use a soft brush to remove dirt from inside the recessed cleat, then apply PTFE dry lubricant to the exposed Spring and Housing within the recessed cleat.
-
Wahoo Speedplay Cleats are intended for road cycling. Off-road, gravel, and mountain biking that exposes cleats to dirt and mud are not recommended.
-
Wahoo recommends replacing your cleats every 3,000-5,000 miles.

1. Clean Crank Arm Threads and apply a small amount of grease.
Use a cloth or brush to remove old grease (if necessary), then apply new grease (not included) onto the crank arm only before continuing to identify and screw on the pedals as described below.
2. Identify Left and Right Pedals
The “wahoo” logo reads left-to-right to help identify each pedal, as shown below. Use the provided washers to allow for at least 1mm space between the POWRLINK ZERO power pod and the crank arm.
Right Pedal:
Left Pedal:
Use the provided washers to allow for at least 1mm space between the POWRLINK ZERO power pod and your crank arm. Repeat on the opposite side.
Caution: Right pedals install clockwise and left pedals install counterclockwise. Improper installation or cross threading can cause damage to pedals or crank arms.
3. Thread the pedals onto the correct crank arm
-
Use an 8mm Allen Wrench to ensure a snug fit.
Recommended tightening torque: 30 Nm. -
-
1. Choose the shims for the base plate that best fit the sole of the shoe
-
5-F and 5-R Shims ship pre-installed to the Base Plates, but may be substituted with the Blue 6-F and 6-R Shims for a better fit.
-
Extra Shims may be required between 5-F/6-F Shims and the sole of the shoe.
Note: While the Base Plate/Shim Combo may not create a “perfect” fit with the bottom of the shoe, for best results simply use the Shims that provide the “best” fit.
2. Screw the Base Plate to the shoe using the provided Base Plate Screws
Recommended tightening torque: 4 Nm.
-
Base Plate Screws ship in two lengths: Short (black) and Long (silver).
-
Use the shortest screws that allow at least five full turns of engagement with the socket in the sole of the shoe.
-
Set the desired fore-aft position then fully tighten the Base Plate Screws.
3. Fit the Cleat Surround around the Base Plate
-
Cleat Surrounds are labeled “L” and “R” for easy identification.
4. Fit the Protector Plate to the Spring & Housing
-
Springs & Housings are labeled “LEFT” and “RIGHT” while Protector Plates are not labeled.
-
The Spring & Housing ships pre-assembled to the Protector Plate. If they have separated, gently snap them together using the two small tabs as a guide.
5. Secure the Assembly to the Base Plate using the Protector Plate Screws
-
Install the Protector Plate Screws using a “Double X Pattern” (shown below). Loosely engage all four Protector Plate Screws.
-
Set the desired left-right position, then tighten the Protector Plate Screws.
Recommended tightening torque: 2.5 Nm.
6. Adjust the Limit Screws to set the desired float
-
Tighten the Limit Screws to reduce the amount of float (“heel movement”) experienced while pedaling.
-
Housings are labelled “Heel In” & “Heel Out” to guide which Limit Screws to adjust.
-
Preferred float range is unique to each rider. If you are unsure of your float preference, begin with medium float and adjust as needed.
-
Note: Do not unscrew the Limit Screws from the Housing when adjusting float, and do not further tighten the Limit Screws once they have made contact with the tip of the Spring.
7. Fit the Cleat Cover over the edges of the Protector Plate
-
Cleat Covers are labeled “LEFT” or “RIGHT” for easy identification.
-
Grip the shoe and apply force with the palm of the hand to each of the four corners to ensure that the Cleat Cover has properly covered the edges of the Protector Plate.
-
The Cleat Cover should fit flush to the Cleat Surround when installed correctly.
Note: Failure to secure a proper fit may result in the Cleat Cover falling off.8. Apply PTFE Dry Lube to the Spring (optional)
-
Reduce the engagement force required to clip into the pedals by applying a small amount of “PTFE Dry Lube” to the Spring. Wipe away any excess lube.

Ensure clearance between shoes and Power Pod
Check that the POWRLINK ZERO Power Pod and your shoe do not touch. Repeat these steps for the opposite shoe. For more information on shoe compatibility, please see the POWRLINK ZERO Shoe Compatibility Guide.
1. With the pedal on the crank arm, clip your shoe onto the pedal. Remove your foot from the shoe.
2. Rotate your shoe around the spindle to check for clearance.
- If there is adequate space between the shoe and the power pod (they should not touch at any point) you do not need to use the Spacer.
- If there is not adequate space then you will need to use the Spacer to provide more space and prevent potential damage to your shoe. Go back to step 2 in the cleat installation instructions to install the Spacer between the Base Plate and Housing.
Caution: Failure to check for pod and shoe clearance may result in damage to your shoe and/or POWRLINK ZERO. DO NOT use POWRLINK ZERO if your shoe comes in contact with the Power Pod. This will void the warranty. - If there is adequate space between the shoe and the power pod (they should not touch at any point) you do not need to use the Spacer.
Additional Information
-
POWERLINK ZERO LEDs blink to indicate the following functions. As a dual-sided power meter, the left pedal acts as the primary and connects automatically to the right pedal and to an app or ELEMNT, while the right pedal connects exclusively to the left pedal (except during firmware updates).
Left Pedal
- Slow blue blink: searching for device (turns off after 30 seconds)
- Fast blue blink: connecting to device
- Solid blue: connected to device (turns off after 30 seconds)
Charging
- 3 red flashes, repeating: Low battery (less than 15% remaining)
- Slow green flashing: Charging
- Solid green: Charge complete
-
Variables like temperature and humidity can influence power meter accuracy. For best results, we always recommended to manually calibrate POWRLINK ZERO before riding.
Manually Calibrate from the Wahoo App:
-
When the pedals are first attached, remember to perform 2-3 quick standing track starts (pedaling hard from a standstill) before initial calibration to ensure proper mechanical seating and settling to ensure performance consistent with regular use.
-
Open the Wahoo Fitness App for iOS or Android and connect to POWRLINK ZERO by clicking Edit to the right of LINKED SENSORS, then use the Add New Sensor button to find POWRLINK ZERO. Always update to the newest firmware, if prompted.
-
Once paired, click on the linked sensor from the bottom of the workout tab and scroll down to Calibrate. Confirm your crank length in the app, then perform a Zero Offset Calibration following the instructions on screen.
Manually Calibrate from ELEMNT GPS Bike Computers:
-
Upon initial setup and with the pedals attached, perform 2-3 quick standing track starts (by simply pedaling hard from a standstill) before the first calibration to ensure proper mechanical seating and settling to ensure performance consistent with regular use.
-
Next, follow the steps outlined in How do I calibrate a Power Meter with the ELEMNT?
Automatic Calibration:
POWRLINK ZERO also calibrates automatically after a ride any time the bike sits in a normal vertical riding position and untouched for longer than 30 seconds to maximize power accuracy.
Note: for more calibration information, see: Understanding Automatic and Manual Calibration.

To get the most from your power meter, it’s important to understand the metrics available. The following list defines each of these available metrics to help you power through like a pro:
-
Power: This is a constant snapshot of the energy you’re expending to ride at any given moment. It is measured in Watts, and represents Energy over a period of time. (1 second or 3 second)
-
Functional Threshold Power (FTP): Measured in watts, FTP is the average power that a rider can produce over the course of an hour.
-
Average Power: This is the total energy (Power) expenditure for a workout, divided by the duration of the selected period (workout or lap).
-
Normalized Power (NP)*: is a method to measure the effect of more intense periods on the overall workout. It is calculated through an algorithm that looks at rolling averages in power over the duration of the workout and is thought to be a better measure of the physiological cost of a workout than Average Power, as it takes into account the variability in workout effort.
-
Intensity Factor (IF)*: This is calculated by dividing NP by FTP (Functional Threshold Power) for the workout.
-
Training Stress Score (TSS)*: Composite score derived by multiplying IF x duration of the workout.
-
Variability Index: A way to measure how smooth or “variable” power output is during the ride. It is calculated by dividing Normalized Power by Average Power. Sprints or climbing efforts will add variability to your workout.
