Setup

This setup guide is intended to assist with installing your Wahoo RPM Cadence sensor on your bike or shoe and pairing to the Wahoo Fitness app.

How to install the Wahoo RPM Cadence on your bike:

Using the Silicone Mount:

Slide the Wahoo RPM Cadence pod into the silicone mount. Make sure the silicone covers the Wahoo logo and the opening is on the back of the Wahoo RPM Cadence.
Thread one zip-tie through the slot on each side of the silicone mount.
Place the Wahoo RPM Cadence on the inside of the non-drive side crank arm. Spin the crank around to make sure the Wahoo RPM Cadence does not interfere with the chain stay on your bike.
Slide the zip-ties through, tighten them down, and trim the excess part of the zip-tie.

Using the double-sided 3M tape:

Make sure the Wahoo RPM Cadence and the inside of the non-drive side crank arm are clean.
Peel off the backing to expose one side of the tape and stick it on the back side of the Wahoo RPM Cadence. Then remove the other side of the tape and stick the Wahoo RPM Cadence to the inside of the non-drive side crank arm.
Spin the crank arm to make sure the Wahoo RPM Cadence does not interfere with the chain stay on your bike.

How to install the Wahoo RPM Cadence using the Shoe Clip Mount:

Take the clip provided and lock in the Wahoo RPM Cadence by sliding it in horizontally and then twisting it vertically into place.
Place on your shoe by threading the velcro strap from your shoe (or similar) through the space in the back of the clip.
Make sure the sensor is attached to your shoe vertically with either the "w" or "o" pointing toward the toe of the shoe. If it is horizontal with all letters facing the toe of the shoe, it will not be able to capture data.

You must connect each sensor separately for each app you use.

NOTE: Bluetooth devices can only pair to one app at a time. Make sure to close any background apps that may be using the sensor before connecting to a new app.
