ROTOR 2INpower DM Road Power Meter
The ROTOR 2INpower DM Road Power Meter makes several improvements over the previous generation ROTOR (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 +/- 1.5% accuracy.

Advice From Our Staff:
This 2INpower is pricey and we understand it’s not in everyone’s budget. However, here’s why we like it: it measures power from both legs, provides left vs. right leg power, the aluminum crank arms are light and stiff and the ROTOR direct mount chainrings further increase stiffness. In addition, this power meter makes it easy to run oval rings if that’s your thing.

The ROTOR 2INpower DM Power Meter is available in the following configurations:
- Crank arm lengths: 165 mm | 170 mm | 172.5 mm | 175 mm

Other Versions to Consider
INpower Version: While the 2INpower you are viewing on this page measures power from both legs, we also have the more affordable ROTOR INpower V3 Road Power Meter which is a complete crankset but measures left leg power only.
Chainrings: The ROTOR 2INpower is compatible with a wide selection of ROTOR chainrings. They are designed to work with 9-, 10-, 11-, 12-, and 13-speed groupsets.
Bottom Bracket: This power meter fits 30 MM bottom brackets. If you currently have a 30 MM crankset on your bike, you should be able to re-use your existing bottom bracket. However, if you are changing spindle sizes, you will need to replace your bottom bracket.
