Rotor-Q 2IN Power

The 2017 Rotor-Q 2IN Power is a power meter. Breaking new ground, the 2IN provides data from both arms, with sensors integrated into the right arm and spindle to deliver comprehensive data. The meter operates off batteries hidden within the bottom bracket, turning on automatically whenever the cranks are in motion. Information is sent over Bluetooth or ANT+ to computer or smartphone. Rotor offers a free software package which provides extensive statistical analysis and recommendations as to choice in chainring. The crankset is compatible with industry-standard 110 center rings.
A very good power meter.
