Dual-Sided Power Measurement
With 2 separate sets of strain gauges, the ROTOR 2INpower measures both left and right leg power data independently.
$1,315.00 – $1,420.00
State of the art design, direct mount chainrings and dual-sided power!
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.
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 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.
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
Chainring shape: Round | Oval
You will need the following tools for installation of this product. You can purchase many of these commonly used tools in our store.
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!
