Upgrade your Garmin Vector 2S Pedals with the Vector 2S Upgrade Pedal and get rolling with even more data tracking. This pedal replaces the right pedal of the standard Vector 2S system, adding a right side tracking pod to turn your bike into a dual sensing data gathering machine. With readings from both pedals, the upgraded Vector 2S system is able to provide data on leftright power balance as well as dynamics that include assessment of where you generate power in each pedal stroke, where you apply force on the pedal, and how much time you spend sitting and standing while riding. This lets you analyze and fine tune your pedal stroke to address any imbalances for a potentially smoother, more powerful ride. As with the sensor less pedal it replaces, the 2S Upgrade Pedal has a lightweight composite body with a stainless steel wear plate to increase durability and provide a wide platform for the cleat, reducing the chances of uncomfortable pressure points. The adjustable tension binding lets you customize the force required to twist the cleat out of the pedal, and the engagement system is compatible with the included Garmin Vector cleats and the ubiquitous Look Keo three bolt cleats. The system is powered by a standard 2032 coin cell battery located in the pedal pod, netting a claimed 175 hours of ride time per battery. When you run through it, the battery is easily replaceable with a quick trip to the convenience store and a twist of the battery cap. The Garmin Vector 2S Upgrade Pedal is available with a standard pedal pod to fit crank arms 12mm to 15mm thick and up to 44mm wide or a large pedal pod to fit crank arms 15mm to 18mm thick and up to 44mm wide. Please note Garmin's 200lb suggested rider weight limit.
