Rotor Inpower Flow MAS Road Bike Power Meter

The Rotor InPower Flow MAS power meter is one of the most accurate and durable power meters on the market. Power is measured a staggering 200 times a second, which is considerably more than competitive power meters manage. The measuring equipment is built into the axle of the crankset and the AA battery powering it all is integrated neatly into the core of the spider. All of this is sealed up with a rugged plastic cover. Your power measurements won’t be affected by weather conditions and interference becomes a thing of the past. The AA battery lasts for around 300 hours, meaning it won’t have to be replaced nearly as often as button cell power meters.

The BB30 axle makes it compatible with almost all bottom brackets. Paring it to the cycling computer is done using ANT+ or Bluetooth.
