Rotor 2INpower MAS Crank

what is this?

In the war against wind resistance, you need every available ally. 2INpower Aero provides the same features as 2INpower but with a closed aero spider to shrug off bullying wind. The aero spider also brings MAS (Micro Adjust Spider) technology to help you micro adjust the orientation of your Q-Rings by approximately 2.5 degrees to fine-tune your pedal performance.

Now you can see 2INpower’s big data in your mobile device and analyze your performance, pedal stroke and post-process your ride.

Just connect your Rotor 2INpower power meter and your heart rate monitor to your mobile devices via Bluetooth.

Track your ride with Rotor's three main App functions - RIDE, BASIC TRAINING MODE and TORQUE 360 mode.
