ROTOR 2INpower DM Road Power Meter

ROTOR’s newest 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 +/- 1.0% accuracy.

 

Key Product Details

Compatibility:

This power meter fits 30 MM road bottom brackets and is compatible with ROTOR Direct Mount Chainrings. See Compatibility tab for more information.

Power Measurement:

This ROTOR power meter has two power sensors (bottom bracket and right crank arm) and measures power from both legs. It is also able to measure your left vs. right leg power.

Key Features:

Dual-leg power measurement, works with ROTOR direct mount chainrings (light and stiff), can measure left vs. right leg power, accurate to within +/- 1.0%, 250 hours of battery life, rechargeable battery, ANT+ and Bluetooth compatible, 2-year warranty. See Specs tab for more information.

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.

 

Options For This Power Meter

The ROTOR 2INpower DM Power Meter is available in the following configurations:

  • Crank arm lengths: 165 mm | 170 mm | 172.5 mm | 175 mm
  • Chainring size: 53/39 | 52/36 | 50/34 | No Chainrings (if you already own them)
  • Chainring shape: Round | Oval | No Chainrings (if you already own them)

 

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 DM Road Power Meter which is a complete crankset but measures left leg power only.

Compatibility

Chainrings: The ROTOR 2INpower DM is compatible with ROTOR Direct Mount Chainrings as listed on this page. They are designed to work with 9-, 10-, 11-, 12-, and 13-speed groupsets.

You will see that you have the option of ROTOR Direct Mount (DM) 1-piece rings or ROTOR 110x4 2-piece rings. Most customers opt for the 1-piece rings as they are lighter and stiffer, however the 2-piece rings allow you to more easily change chairing sizes in the future, should that need arise.

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 chaining spindle sizes, you will need to replace your bottom bracket.

      Hi Horacio. We’ve been really impressed with the new 2INpower. It’s a great all-around power meter and if you want to run oval rings – it’s arguably the best option. Keep up the good work!
