2INpower Road 110x5

Dual-sided 2INpower measures power individually in each leg to provide precise data about balance and power output in order to demonstrate where improvements can be made to pedaling performance. As the name suggests, 2INpower evolved from ROTOR´s INpower, the power meter integrated inside the crank axle that measures power in the left leg. Two additional sets of strain gauges haven been placed in the right crank arm, which will measure power exclusively in the right leg. INpower´s four strain gauges are located in the crank axle and measure the left leg´s power output. New to 2INpower are Bluetooth Smart functionality and a built-in rechargeable battery, which are features in addition to those of INpower.   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.   Chainrings are sold separately, purchase here - Direct Mount    Characteristics: Sizes: 165/170/172.5/175mm Battery specifications: Rechargeable Li-ion+USB cable Estimated battery life: 300 hours riding time Strain gauges: 4 gauges in the axle; 4 in the righ crank arm Wireless technology: ANT+™, Bluetooth Smart Weight: 645g (172.5mm/110 BCD) Data transmitted: power, balance, cadence, TORQUE 360, OCA, torque effectiveness (L/R) pedal smoothness  Head unit: ANT+™, Bluetooth Smart compatible head units http://www.thisisant.com/directory Analysis Software: Trainingpeaks.com/ROTOR Crank Software: ROTOR 2INpower User Software Q-Factor: 148 mm Chainline: 43.5 mm Material: 100% CNC-machined, 7055 aluminum alloy Compatibility: bottom brackets BSA, ITA, BB86, BB30, BB30A, PF30, BBRight, BB386 Evo, oval and round chainrings, 110 BCD, 9,10 and 11-speed 2INpower User Manual - English All other INpower downloads can be seen here
