Light, compact and easy to fit, the Wahoo RPM Cadence Sensor is an easy add-on for any cyclist wanting to be able to monitor their pedalling rate.

The RPM uses an accelerometer which means you don't need to attach a separate magnet to the chainstay, as needed by most other cadence sensors. That means it's very easy to install, you simply use the double-sided tape or rubber carrier and zip ties to affix it to the non-driveside crank arm, and you're all set.

You'll need a device, such as a Garmin or smartphone, that can communicate with the cadence sensor via either Bluetooth 4.0 or ANT+. I used the latter and the sensor quickly and easily synced with my Garmin Edge 500. If you use a smartphone you can use any app such as Strava, MapMyRide or Wahoo's own Fitness App to make use of the cadence data.

An LED indicates activity, blue to signal Bluetooth connection and red to signal cycling cadence detection.

In testing I found it took about 5-6 seconds for cadence data to be displayed when setting off, but once the sensor was engaged it provided reliable and consistent data with no spikes or anomalies noticed during riding.

The slight delay is an issue if you doing very short intervals on a turbo trainer and want to use cadence, but out on the road and in normal cycling it caused no issue at all. It makes it very easy to monitor your cadence when pedalling, and can help you to hone your pedalling technique or work on certain aspects of training, such as high gear low rpm climbing drills for example.

I've been using 3M double-sided tape, because it's really easy to use, and any concerns about the sensor peeling away when riding through a range of weather conditions, and purposefully splashing through muddy puddles, soon faded away. It didn't budge.

It takes all of five minutes to fit and set up the RPM Cadence Sensor and it works from the off. It's a really easy, lightweight (just 8g) and relatively affordable way to add cadence to your cycling. It's powered by a single coin cell battery and the manufacturer claims it's good for two years; I've not had it long enough to challenge that claim yet.

Verdict

Simple, light and easy way to add cadence data to your cycling
