The purveyors of iPhone powered fitness devices now have their sights set on cadence sensors. Thanks to the new Wahoo RPM Cadence Sensor, constantly misaligned magnets are a thing of the past. The tiny 7g, coin cell operated RPM simply affixes to your crank and pairs with most Bluetooth 4.0 or ANT+ compatible devices to provide the necessary cadence feed back. Due to the fact that the RPM does not use magnets, it can also be installed on your shoe as a footpod for public spin bikes, or if you want to easily use it on multiple bikes.
Battery life, installation requirements, and more, next…
If you choose to mount it to y our bike instead of your shoe, the RPM can be mounted to the non-drive crank arm in two ways. Included double sided 3M tape will allow it to be mounted as cleanly as possible, or you can use the silicone sleeve and zip ties for a more conventional mount. At only 7 grams, the RPM is extremely light and will operate up to 2 years on a single coin cell battery.
Available for $49.99, the RPM is compatible with iPhone 4s and newer (running the latest ios), as well as compatible Android devices, iPod Touch 5th gen, and iPad 3rd and 4rth gen as well as other devices with Bluetooth 4.0 or ANT+ connectivity. The sensor is also compatible with a number of popular cycling apps like Strava, MapMyRide and Cyclemeter.
