Tested in extreme conditions and rated IPX7 waterproof, it is built to endure mud, rain and harsh environments, all backed by an industry-leading 3-year warranty.
While you're off the bike, Find My remains active and allows you to view the powermeter’s location on your iPhone, iPad, Mac, or Apple Watch. Adding it to the Find My app is simple, making it easy to keep track of your bike—whether stored, misplaced, or left behind.
