About the ROTOR INpower DM Power Meter

As with the previous generation INpower, the ROTOR INpower DM 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 configuration. The ROTOR INpower DM has ANT+ and Bluetooth SMART functionality, is powered by a AA battery with 300-hour battery life and features +/- 1.0% accuracy.

 

Options

The ROTOR INpower DM Power Meter is available in the following configurations:

  • Crank arm lengths:
    • 165 mm | 170 mm | 172.5 mm | 175 mm
  • Chainrings:

    • 110×4 DM Q-Ring: 53/39 | 52/36 | 50/34

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

 

Compatibility

The INpower uses a 30 mm Universal Bottom Bracket (UBB) system. UBB30 is compatible 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.

The only frames not compatible with the UBB30 system are BB90 and BB95 (both for 24 mm diameter axle).
