ROTOR 2INpower SL Road Power Meter

The all-new ROTOR 2INpower SL Road Power Meter is lighter and more affordable than ever! Weighing just 530 grams (170 mm) the 2INpower Super Light Road is 15% lighter than the previous model and is now the lightest dual-sided power meter on the market. Using ROTOR’s Trinity Drilling System along with aeronautical grade 7075-T6 aluminum, the crankset is not only lightweight, but also ultra-stiff. This means better power transfer and increased efficiency.

The 2INpower also features dual-leg power measurement with two sets of power sensors. This allows you to see total power as well as left vs. right leg power balance. In addition, the power meter is accurate to +/- 1.5% making it one of the most accurate power meters available. It also features automatic calibrations (no rider offset required).

The ROTOR power meter comes with a user-friendly app that provides personalized data and detailed graphs for in-depth analysis and training along with dual ANT+ and Bluetooth connectivity. The built-in rechargeable battery charges in just 3 hours and provides up to 250 hours of life.
