Garmin Speed Sensor 2 Kit
Monitor your speed as you ride with this easy-to-install wireless sensor.
With no magnets or other exposed parts to line up, this sensor is easy to install, maintain and move between bikes. The Speed Sensor 2 attaches to the hub of either wheel.
You can set up wheel size in our Garmin Connect online community or self-calibrate. Once set up, you'll get accurate speed and distance at all times - even without a head unit.
ANT+ connectivity and Bluetooth Low Energy technology let you sync to Garmin Connect and other training apps. The odometer feature tracks your distance to help plan for bicycle maintenance.
