Revolutionize your training with the Rotor 2INpower! Bilateral powermeter with integrated power measurement in the axle and right crank arm, will improve your training in quality and experience. This crankset is based on the well-known Rotor INpower power measurement system. The 2INpower measures the power individually from each leg. This provides accurate data on balance and power and potential for improving pedaling performance. The power measurement of the left leg is measured INpower typical in the axis, via two pairs of strain gauges. Two pairs of additional strain gauges are placed in the right crank arm, these measure right leg power only. This allows independent or combined pedaling analysis using Optimum Chainring Angle(OCA) and Torque360 metrics in the free user software.2INpower bilateral power meters that measure power in each leg separately and accurately analyze power variations during a pedal revolution. Torque360 and Optimum Chainring Angle readings complement ANT+ and Bluetooth Smart protocol readings, including cadence, balance, torque effectiveness and cadence uniformity, to provide accurate data on your power output. The 2INpower's rechargeable batteries last up to 250 hours and can be charged 300 times during their lifetime. - Intended use: MTB - Details: - Rechargeable lithium-ion battery - Battery life: up to 250 hours - Compatibility: BB30 / Pressfit 30 / BSA / BB89 / BB92 - Wireless technologies: ANT+, Bluetooth Smart - Protected electronics in the axle and in the right crank arm - Black bumpers protect against rock contact - Boost standard - Powermeter Material - Crank arm(s): 7055 aluminum Scope of delivery - Included: Rotor 2INPower crank arms incl.
