The Garmin Rally™ RS200 Dual-Sensing Power Meter Pedals deliver reliable power measurements and easiness to transfer between bikes. These pedals are built to help you track your performance, and, in addition to total power and cadence, they measure much more helping you tailor your training around your specific weaknesses and strengths to help you improve. Measure power from your left leg versus power from your right leg to get a better look at how symmetrically you are producing power, track the amount of time you spend in each position while gauging position effectiveness, and ensure proper cleat position by keeping track of where power is applied on the pedal as well as where in the pedal stroke you are producing power. They are impeccably designed, featuring sensors housed inside, plus, an ultra-easy installation so you can transfer between bikes as well as a long-lasting battery for long rides and training sessions, thanks to their up-to-120-hours of battery life. Take your cycling to the next level with the Garmin Rally™ RS200 Dual-Sensing Power Meter Pedals!
