Stages Cycling Power R Dura-Ace R9200 Right Arm Power Meter STD92RA4

Stages Cycling Power R Dura-Ace R9200 Right Arm Power Meter Stages Cycling's Power R Dura-Ace R9200 Right Arm Power Meter offers very accurate power measurement to make training more effective and better gauge race-winning efforts. Accuracy is ± 1.5%, with Active temperature compensation ensuring weather changes don't affect recordings. Power outputs up to 2500 watts can be measured so even the strongest sprinters are well catered for, and battery life from the CR2032 battery is excellent - up to 200 hours riding time. Communication with head units or smartphones is via Bluetooth or ANT+, so the power meter is compatible with the vast majority of devices as well as popular training apps such as TrainerRoad and Zwift. Firmware upgrades are also done wirelessly, so there is no need to physically connect the power meter to a computer to benefit from the latest releases. The power meter is fitted to the drive side crankarm of a Shimano Dura-Ace R9200 chainset and includes the appropriate Shimano chainrings too. It is particularly useful for a small number of bikes and frames that do not have sufficient clearance to use a left-side power meter.  Includes Drive side power meter Shimano Dura-Ace R9200 crank and chainrings High-quality CR2032 coin cell battery Lifetime access to Stages Link for power meter management and firmware upgrade Two months free access to Stages Link premium training and coaching features Product Identification Card with Serial Number and ANT+ ID Number User Guide
