SETUP

HOW TO INSTALL THE WAHOO BLUE SC

  • Place the sensor on the rear chain stay of your bike, near the pedal. The logo should be facing up and the arm of the sensor should be inside the rear chain stay, facing down. You may need to loosen the arm of the sensor with a 2mm allen wrench to move it into the correct position.
  • Secure the sensor in place with the provided rubber band or zip-ties, whichever is preferred. If using zip-ties, do not completely tighten yet, as the magnets still need to be aligned before completely securing the sensor in place. We recommend using the zip-ties for the most secure connection.
  • Take off the pedal on the same side and slip the pedal magnet onto the crank, magnet facing in towards the sensor. Align so that the magnet will pass by the indicator line on the body of the Wahoo Blue SC sensor. The magnet will have to pass within 1/8 inch (about 4mm) to get a reading. As such, adjust the position of the sensor and/or magnet if required. Replace your pedal.
  • Screw the wheel magnet onto any spoke on your back wheel, facing in towards the sensor. Align so that the magnet will pass by the indicator line on the arm of the Wahoo Blue SC sensor. The magnet will have to pass within 1/8 inch (about 4mm) to get a reading. Once again, adjust the position of the sensor and/or magnet if required. Tighten the magnet in place on the spoke. Once satisfied with the magnet positioning, tighten and snip the ends of the zip-ties (if using).

  • Download the Wahoo Fitness app from the App Store.

  • Select "Sensors” in the bottom left corner.
  • Select "Add New Sensor."
  • Choose your Blue SC from the list of available sensors.*
  • Once certain you are connected to the correct sensor, select "Save Sensor."

  • Open the Wahoo Fitness app. Make sure you have Bluetooth turned on.
  • Wake up your Blue SC by rotating your rear wheel or crank arm until the magnet passes by the sensor.

Your Blue SC is now set up and ready for action. To use your Blue SC, start a workout with one of the profiles you paired it with. The Wahoo Fitness app will remember this pairing in the future. You simply need to wake up your sensor and start a new workout to begin recording data!

NOTE: The Blue SC speed and cadence sensor uses a Blue and Red LED to give instant feedback to the user during the pairing process. These LEDs operate for about 30 seconds before shutting off to conserve battery. The Red LED flashes with a single blink for the crank, a double blink for the wheel. The Blue LED represents your connection state and has three modes:

  • Slow Blink (about once every second): Blue SC is awake and not paired.
  • 4x Flash: Occurs the instant a connection is made.
  • Quick Blink (about twice every second): Blue SC is paired to a device.

If a firmware update is available for your sensor, the Wahoo Fitness app will now prompt you to proceed with performing an update. If you do not, the update may be performed later. Sensors with updates available will appear in the menu of Saved Sensors marked with a badge to indicate the update is available but not installed.

HOW TO REPLACE THE BLUE SC BATTERY

  1. Insert a coin, or other tool in the slot located on the back of the Wahoo Blue SC to twist and battery cover off the Blue SC body.
  2. Remove the battery and replace it with another CR2032 coin cell battery.
  3. Place the lid back onto the Wahoo Blue SC. Make sure the rubber O-ring is properly seated.
  4. 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.

NOT WORKING?

Make sure the magnets are aligned to pass by the sensor as the crank and wheel spin

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. Devices can only pair to one app at a time.
