The Wahoo RPM speed sensor is the sleek, magnet-less solution for capturing cycling speed data. The Bluetooth Smart and ANT dual band technology allows you to wirelessly connect to and display data on both smartphones and bike computers.
UNIVERSAL FIT SLEEK DESIGN
RPM Speed will fit with most bikes and frame sizes. It only weighs 16.5 grams with the mount included and you can mount it on any front wheel hub with a secure silicon casing - no magnets required.
Two LED lights show the sensor's device connection (blue) and speed detection (red).
