The Stages Power L - Shimano Dura-Ace R9200 is built onto the non-drive side Dura-Ace R9200 crank arm and is compatible with Shimano Hollowtech II road drivetrains. It measures left sided power or, combined with a right power meter, dual power. Power is a valuable training aid, used at all levels of cycling to shape both the training and race strategy of riders. Weak areas can be detected and worked on, while strengths can be exploited and optimum pacing adopted to maximise your efficiency in every event. Stages power meters are known for contributing to Grand Tour, Olympic and World Championship victories, thanks to their impressive +/- 1.5% accuracy level, robustness, extremely light weight and longevity. The power meter itself adds just 15g to the crank arm, while the battery can last 200+ hours when paired with a single sided meter. It is also extremely reliable, since it has a water resistance rating of IPX7 and the built-in temperature compensation common to all of Stages’ power meters. So, wherever you choose to ride, in whatever conditions, you can count on getting accurate readings. Finally, Stages’ technology is compatible with all the most popular training apps around, including Training Peaks, Strava and Garmin, so it will fit into your training routine and enhance it through lifetime access to the Stages Link platform, along with its many courses, workouts and analytic tools. Compatible with all frames that include the stable 12-speed Shimano Hollowtech II road bottom bracket, the Stages Power L Shimano Dura-Ace R9200 will breathe new life into your training plan to help you achieve your goals.
