ROTOR INpower DM Road Power Meter

Description

ROTOR INpower DM Road Power Meter
As with the previous generation INpower, the ROTOR INpower DM Road Power Meter measures left leg power using two sets of opposing strain gauges in the axle. The strain gauges are able to measure power, cadence, torque effectiveness and pedal smoothness. In addition, because all of the electronics are housed inside the water-proof, sealed axle, the power meter is super durable and can withstand the harshest conditions.
However unlike the previous generation power meter, the new INpower DM uses ROTOR’s Direct Mount Chainrings. The Direct Mount rings are machined from a solid block of 7075 aluminum which makes them lighter and stronger than the standard 2x chainring set-up. The ROTOR INpower DM has ANT+ and Bluetooth SMART, is powered by a AA battery with 300-hour battery life and features +/- 1.0% accuracy.

The ROTOR INpower DM Power Meter is available in the following options:
Crank arm lengths:

Please note – the ROTOR INpower DM is only compatible with ROTOR Direct Mount Chainrings.

The INpower uses a 30 mm Universal Bottom Bracket (UBB) system. UBB30 works with almost all standard frames in the market (when used with the correct spacers).
Specifically, UBB30 is compatible with the following standards: BB30 (68/73 mm), PF30 (68/73 mm), BSA threaded, ITA threaded, BBright and BBright Direct Fit, BB86, BB386 EVO, BB89 and BB92.
