Rotor 2inpower MAS Power Meter

The Rotor 2inPower MAS is a power meter which measures your power on both sides of the crank. This enables you to get a read-out of your left and right power separately. It also allows you to perfect your pedalling motion and determine the optimal chainring setup. The MAS version has the most adjustability for the chainrings and perfectly matches up with them to form a single aerodynamic whole. The electronics are sealed behind a plastic cover. Since the data is gathered inside the spindle, the signal is crystal clear (smaller chance of interference) and is transmitted via ANT+ or Bluetooth Smart.

The Rotor 2inPower weighs around 645 grams at a 175 mm crank length. The Q-Factor measures 148 mm (distance between the left and right crank at the pedal mounts). The system uses a simple AA battery which lasts an impressive 300 hours before you need to replace it. The Rotor 2inPower measures your power 200 times per second, unique for a power meter, which enables you to run with non-round chainrings. It shows you cadence, power balance between left and right, as well as pedal efficiency on both the left and right.
