SETUP

HOW TO INSTALL THE WAHOO RPM SPEED ON YOUR BIKE

  • 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.

HOW TO REPLACE THE WAHOO 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.
  • Additionally, Wahoo does not recommend the use of any battery with a “bitter/child deterrent” coating (specifically, but not limited to those made by Duracell). These batteries are not approved for use Wahoo devices and may only be used at your own risk should you choose to. This coating has the potential to reduce battery performance and may degrade sensor functionality. Wahoo recommends using Panasonic coin-cell batteries or another name brand without a bitter coating for optimal performance and tracking.
