Power Meter

CINCH Power Meter utilizes a 30mm spindle body with 129mm road spindle length and 134mm mountain spindle lengths available. Utilizing an Easton or Race Face BB compatibility guide can assist you in determining if your bicycle is compatible with the CINCH Power Meter.

Utilizing the CINCH Power Meter App you can check battery levels on your CINCH Power Meter.

The product is designed to provide excellent water resistance and tested to resist water penetration to the IPX7 standard (up to 1 meter). This provides outstanding water resistance for cycling conditions both off-road and on-road, including stream crossing, heavy rain and bike washing. Please keep in mind that electronic devices are inherently sensitive to water and that there are limits to the water resistance. Do not subject the product to direct spray from a high pressure sprayer. It is possible for water to be forced past the seals and damage to the electronics may occur.

Note: To help with protection of the antenna and insure maximum water resistance please keep the antenna cap on and securely fastened at all times, except when charging. 

Yes, the CINCH Power Meter firmware is easily upgraded via the CINCH Power Meter App. The CINCH Power Meter App is available for both Apple iOS and Android compatible devices.

Both applications connect to the power meter via Bluetooth®.  The App utilizes your data or WiFi signal to indicate if a more recent firmware is available and asks if you would like to download and install it.  Installation time will vary depending on Bluetooth connection but normally takes just a few minutes to complete.  There is no need to remove the battery, do a zero reset or anything else, just update the firmware and you're ready to ride.

The battery will last about approximately 400 hours of running time between charges.

Many ANT+™  enabled head units display a low - battery warning when a sensor, such as the CINCH Power Meter, battery level drops below 10% remaining. Once this warning is displayed you still have approximately 10 hours of battery life left in the CINCH Power Meter.  When the Low Battery Warning is displayed it is recommended that you recharge your CINCH Power Meter.

You can also verify battery levels utilizing the CINCH Power Meter App.

The product contains a rechargeable Li-Ion battery, do not try to replace battery as this will void warranty and potentially damage the product.

The rechargeable Li-Ion Battery must be serviced by Race Face / Easton Cycling.

Please refer to local regulations regarding air transport of the power meter and Li-Ion batteries.

There can be a number of easy to fix issues to double check before contacting service.

Confirm the CINCH Power Meter has been taken out of Airplane Mode.

Please check connectivity or positioning of you head unit – at times placement of the head unit can affect signal transmission.

The zero offset needs to be set. Utilize the instructions for calibrating CINCH Power Meter either using CINCH Power Meter App or the menu in your head unit.

The battery is almost empty – please confirm the CINCH Power Meter is fully charged.

Finally there could be damage to the CINCH Power Meter circuit board or attenna.

Calibration, also known as zeroing, is an important step in ensuring the accuracy of the power measurement generated by the CINCH Power Meter. Changes in bolt torque, crank configuration and a number of other factors can impact the calibration of a power meter. The purpose of zeroing/calibration is to align a zero measurement from the CINCH Power Meter with a real world zero value where your power meter is in a static state.


There is no need to calibrate the CINCH Power Meter for every ride, but periodic calibration is recommended and especially after any mechanical changes to the crank such as changing pedals, chain rings, installation of the crank, tightening of bolts etc.


Calibration Process

- Turn on the CINCH Power Meter (Achieved though turning the cranks).

- Place the bike in the upright position and the left (non-drive) side crank arm pointing straight down (pedal closest to the ground). Do not put any weight on the pedals.

- Using an ANT+ bike computer, follow the instructions for the bike computer to send the CALIBRATE command. Typically under Settings/Bike Profiles/Bike/ANT+ Power.

- Using a smartphone connected through BLE, use the CINCH Power Meter app and select Calibrate in the menu.

- Calibrate.

Though you can likely switch between 1x direct mount chainrings with little change, swapping from 1x to our 2x shifting rings we recommend running a quick Calibration before you ride.

No. This will destroy the Power Meter and void your warranty.

Utilize the CINCH Power Meter App to confirm you have the latest firmware update. If you do, run the battery through a full cycle (run from full until empty) and charge fully again to see if this changes.

If there is no change in battery condition, please contact customer support.

Power meters run on a baseline, and the data they output is often relative to a number of conditions. Things that can change the power output: cold, wind, tire pressure. We can have our technician look at your data if you go to the upload area of the app.

No, the CINCH Power Meter tracks cadence internally.

129mm Road Spindle is rated for Road, Tri, CX and light XC

134mm MTB Spindle is rated for XC, Trail and Enduro

Power: This is the instantaneous power output typically measured in watts which is calculated by multiplying torque by cadence. Power data is transmitted to the head unit and 2 Hz (twice per second) with the maximum frequency of power display typically being every second.

Most ANT+ enabled head units also have various power averaging and maximum power display options that are all based off this power number. Please refer to your head unit user manual for details.

Cadence: Cadence is measured by built-in accelerometers

Torque effectiveness:  Indicates what percentage of your total pedal stroke power is being used to move the bike forward.  The remaining percentage (100%-TEff) is the amount of pedal stroke power you are essentially wasting either by not completely lifting your leg on the upstroke or applying power in a useless direction (backwards).  Values of 60-100% are typical. A value of 100% indicates that all of the power delivered on the pedal stroke was in the forward direction.

Pedal smoothness:  Indicates how evenly power is being applied over one rotation of the crank. Values of 10-40% are typical.  A lower value would indicate power is being applied quickly in only one part of the pedal stroke.  A higher value indicates the power is being applied more evenly over a bigger range of the pedal stroke.
