Why XC Racers Choose the 4iiii Precision 3+ for Shimano XTR
Mountain bikers who train with power have a real advantage on race day, and the 4iiii Precision 3+ makes that accessible without the bulk. Designed to bolt directly onto your Shimano XTR FC-M9100 crank arm, it adds virtually no weight while delivering +/-1% accuracy across every terrain type. Apple Find My support means your powermeter is trackable if a crash sends it flying, and Bluetooth plus ANT+ dual transmission ensures seamless pairing with Garmin, Wahoo, or whatever head unit you roll with.
The automatic terrain selector is a standout feature for mountain bikers specifically, continuously recalibrating cadence detection as you move between flowy singletrack, steep punchy climbs, and technical descents. Up to 800 hours of battery life from a single CR2032 means you will not be thinking about swaps for months at a time, and 4iiii's 3-year warranty has you covered for the long haul. At 170mm, this is the right tool for XC and marathon racers who want real power data dialed in to their Shimano XTR build.
