pioneer-sbt91-dura-ace-r9100-power-meter-crankset-165mm-11-speed-52-36t-110-asymmetric-bcd-hollowtech-ii-spindle-interface-black, The SBT91 series of Power Meter Cranksets provide precision dual arm power meter measurements with advanced pedaling monitor capabilities. Pioneer Power Meter sensors are factory pre-installed and precision calibrated on Shimano's Dura Ace R9100 crankset.Four directional strain gauges and dual accelerometers per arm work together to precisely measure pedaling force, as well as Pioneer's proprietary force direction and pedaling efficiency measurementsThe smaller left arm chassis design provides maximum bike compatibility, including TREK bicyclesEasy connection to ANT+ cycle computers and running watches for displaying Power, Power Balance, Cadence, Pedaling Smoothness, Torque Effectiveness, NP, IF, and TSS power metricsBluetooth BLE Connectivity for easy set-up, maintenance, and Live Pedaling Viewer via Pioneer Cyclo-Sphere Control app for iOS and AndroidPioneer Pedaling Monitor Power Metrics, on Pioneer's cycle computers, provide real-time display of Force Vector, Torque Chart and Pedaling Efficiency metrics. NOW Pioneer Pedaling Monitor Power Metrics are available on Wahoo ELEMNT and ELEMNT BOLT cycle computersIncreased environmental resistance, certified with IP66 and IP68 resistance rating against the intrusion of harmful water and dustTwo years parts and labor factory warranty
