For any cyclist that follows the "n+1" bike ownership rule, you will more than appreciate the RPM Cadence Sensor from Wahoo. Instead of buying a speed and cadence sensor for every single bike in your garage, the magnet-less RPM is a dream to switch from one bike to another, meaning you can instantly move back and forth from your gravel bike, to your winter bike, to your commuter, on to your fat bike, then your mountain bike – you get the picture.
