Designed for trailblazers and endurance riders alike, the 4iiii XT Precision 3.0+ Power Meter delivers pro-level performance in a compact, lightweight design. Built onto a Shimano XT crank arm, this single-sided power meter offers ±1% accuracy, making it a trusted training tool whether you're navigating technical singletrack or grinding through virtual intervals on Zwift. It's engineered for the demands of mountain biking, gravel, and adventure riding, where data-driven performance matters most.

With a massive 800-hour battery life, the XT Precision 3.0+ is built for long hauls and harsh conditions. It’s equipped with an automatic terrain selector, ensuring precise readings across varied landscapes. Data including power output (watts), cadence, and calories burned is transmitted to your preferred cycling computer or smartphone via Bluetooth Smart and ANT+, keeping your training seamless and insightful from trail to trainer.

The game-changing addition of Apple Find My integration means you'll always know where your power meter is—even when it’s off the bike. Just link it to the Find My app to track it across your Apple devices. With its IPX7 water resistance, compact design, and 3-year manufacturer’s warranty, the 4iiii XT 3.0+ is the ideal upgrade for serious riders looking to track, train, and perform with total confidence.
