Stages Cycling has been in the cycling technology business for over ten years, with dozens of our employees bringing vast industry expertise to launch and drive the company. Stages is the global leader in commercial indoor bike and power meter production. Stages Power meters are all hand-crafted by our beloved production team in Boulder, Colorado, USA, working alongside Stages engineers, whose number one initiative is to propel innovation.Stages Power has carried riders to three consecutive Tour de France victories, plus many more world and national championships. If you believe racing provides the world’s best product proving ground, then Stages Power is proven as the world’s best power meter. Stages Power LR is built on to a Shimano ULTEGRA R8100 crank set, placed on both the drive and non-drive side of the crank in order to independently measure a rider's left and right legs. Consistency of measurement is the most important feature of a power meter. Stages Power was the first meter to make temperature compensation an automatic process ensuring accurate readings no matter the environmental conditions. ATC is the key reason a rider can trust data from Stages Power in all conditions. Each Stages Power meter is calibrated individually to ensure a +/- 1,5% accuracy level, which is an industry best for non-scientific power meters. Individual calibration for the dual-sided option means that you can trust the data produced by our system, as it's a real measurement and not an estimation.Stages Power LR (LEFT and RIGHT side) power metersRight and left crank arms for Shimano ULTEGRA R8100Chainrings included, teeth combination (OPTIONAL): 50-34 OR 52-36Accuracy: +/- 1,5% in all conditions Individual meter calibration for the most accurate resultsActive temperature compensationWirelessly upgradable firmwareLED indicator for visual indication of battery levels and zero reset confirmation without connected app or headunitAccelorometer and addition of gyroscope for improved cadence resolutionBLE and ANT+ offer a 6x improvement of data transmission strength, comparing with previous generationsPower meter housing has low profile design, with robust interfaceWeight: 1267 gBattery: single CR2023Battery life: up to 200 hoursPower range: 0 - 2500 WCadence range: 20 - 220 RPMWater resistance rating: IPX7Crank length (OPTIONAL): 160mm, 165mm, 170mm, 172.5mm, 175mm.COMPATIBILITY: Shimano ULTEGRA R8100 cranksetCompatible with most frames, see fit guide in Stages Support section Compatible with Stages Link, Training Peaks, Strava, Garmin Training Center and other software Compatible with ANT+, Bluetooth Smart Ready devicesINCLUDES: Right and left crank arms with chainrings and Stages Power R drive-side power metersHigh quality CR2032 coin cell battery Lifetime access to Stages Link for power meter management and firmware upgrade2 months free access to Stages Link premium training and coaching featuresProduct Identification Card with Serial Number and ANT+ ID NumberUser Guide
