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.
The Wahoo RPM is a wireless (Bluetooth 4.0), magnet-less, and lightweight (7 grams) cadence sensor. The sensor is dead easy to install – it comes with both double sided 3M tape for those that want to keep it on one bike, or a silicone sleeve for you to mount with zip ties. I chose the zip tie option as I have been moving the sensor between my road bike and my mountain bike.
Similar to any of your other Bluetooth sensors, the RPM connects wirelessly to your iPhone and displays your cadence data within your app of choice. I had no problems syncing the sensor with Strava – the app picked up the RPM almost immediately. Interesting to note, however, is that the RPM showed up under the Speed & Cadence section versus just the Cadence section under Manage Sensors. If you run into problems for any reason, LED lights on the RPM flash to let you know you are properly connected.
You never need to charge the RPM, as the sensor runs on a coin cell battery similar to any watch. The battery should last for up to 2 years before you have to worry about replacing it with a new one.
Bottom Line: If you use a smartphone app to record your rides, you already have speed data covered. For capturing cadence data, never worry about losing a sensor magnet and easily switch between bikes with the Wahoo RPM.
The Wahoo RPM Cadence Sensor retails for $49.99 and is available now.
