About the ROTOR 2INpower DM Power Meter

ROTOR’s newest power meter, the ROTOR 2INpower DM Power Meter, makes several improvements over the previous generation ROTOR power meter (the INpower). Perhaps the biggest change is the 2INpower features independent left/right power measurement. ROTOR has added two additional sets of strain gauges to the right crank arm that measure right leg power. Four strain gauges located in the crank axle measure the left leg’s power output (as is the case with the previous INpower version).

In addition, the 2INpower DM features 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 2INpower DM has Bluetooth SMART functionality, a built-in rechargeable battery and features +/- 1.0% accuracy.

 

ROTOR 2INpower DM Highlights

Dual-Sided Power Measurement

With 2 separate sets of strain gauges, the ROTOR 2INpower measures both left and right leg power data independently.

Direct Mount Chainrings

The DM rings are machined from a solid block of aluminum. This makes them lighter and stronger than conventional chainrings.

Bluetooth SMART Technology

The 2INpower DM features dual ANT+ and Bluetooth SMART Technology. This allows you to use the power meter with any cycling computer, smartphone or tablet.

Integrated Electronics Inside

The electronics and battery are integrated inside the axle, making the ROTOR power meter shock and contaminant resistant.

Optimized for Q-Rings

TORQUE 360 and OCA (Optimum Chainring Angle) allows you to adjust your chainrings with maximum precision for optimized pedaling efficiency.

Universal Bottom Bracket (UBB)

With its UBB, ROTOR 2INpower cranks are compatible with almost every bike frame in the market.

ROTOR Power Meter Compatibility

The 2INpower 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). The ROTOR power meter can be installed on your bike even if your current cranks are 24 mm diameter.

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).
