ROTOR 2INpower Track Power Meter

ROTOR has brought their popular 2INpower power meter technology to the track! Initially only available in road and MTB versions, the ROTOR 2INpower Track Power Meter is now here! Just like the 2INpower road and MTB power meters, the 2INpower Track features dual-sided power measurement (one of only two track power meters with this feature), dual ANT+ and Bluetooth SMART functionality, a built-in rechargeable battery with 250-hour battery life and +/- 1.5% accuracy.

In addition, the track version uses a proper 144 BCD with a 43 mm chainline, making it ideal for track use. The power meter is currently offered in sizes 165 mm – 175 mm and can fit any 144×5 track chainring.

Advice From Our Staff:

This is a fairly expensive power meter, however we note that when it comes to track power meters, it slots somewhere in the middle. In any event, if it’s in your budget, we think it’s worth considering. ROTOR makes really good products and it’s also one of only two track power meters that can measure left vs. right leg power. In addition, the aluminum crank arms on it are very light and stiff.

Question: How do I determine what length my current cranks are so I can make sure I get the same size?

  • Your crank arm length should be printed or stamped on the inside of the left crank arm, usually near the pedal end.
