HOW TO INSTALL RPM SPEED ON YOUR BIKE
- Slide the Wahoo RPM SPEED pod into the mount supplied. Make sure the Wahoo logo is facing outwards on the flush side of the housing and the back of the Wahoo RPM SPEED faces toward the hook side of the mount. The hooks should be facing downward.
- Slide the rubber shim-strap into the back (the hooked) side of the mount so that the three prongs of the strap fit snugly up against the top two hooks of the housing. The Wahoo RPM SPEED is now ready to fit to the hub of either wheel as per your preference.
- While holding the mount in place on your selected hub, gently stretch the strap portion of the rubber shim-strap around the hub and secure using the bottom two hooks on the mount. When installed correctly, the Wahoo RPM SPEED should not be in contact with any other parts of your bike.
Your Wahoo RPM SPEED is now ready to be paired with the Wahoo Fitness app.

WANT TO CONNECT TO ANOTHER APP?
This product is compatible with a number of third party apps. However, each app connects to sensors a little differently. As a general rule: Open the compatible app you would like to use and find the settings. Look for "connect to sensor" or another similar option. 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.
MAINTENANCE AND TROUBLESHOOTING
REPLACING THE RPM SPEED BATTERY:
- Insert a flat-head screwdriver, coin, or other tool in the slot located on the side of the Wahoo RPM Speed to twist and pop off the top cover.
- Remove the battery and replace it with another CR2032 coin cell battery.
- Place the lid back on the Wahoo RPM SPEED. Make sure the rubber O-ring is properly seated and the two posts on the bottom of the Wahoo RPM SPEED are lined up with the holes in the lid of the Wahoo RPM SPEED.
- Make sure the lid is snapped back into place and sealed completely around the outside. The LED light should start to flash showing that the battery has been replaced and the Wahoo RPM SPEED is awake.
- Wahoo recommends using Panasonic coin-cell batteries or another name brand without a bitter coating for optimal performance and tracking.
