Factory-installed onto a Shimano Dura-Ace R9200 crank arm, it offers ±1% precision, an impressive 800 hours of battery life, and a built-in terrain selector that adapts your data to real-world conditions—whether you’re racing for the podium or chasing your next personal best.

More than just a power meter, the 4iiii Precision 3.0+ becomes your digital training partner. It transmits live metrics such as watts, cadence, and calories to your compatible head unit or cycling app using ANT+ and Bluetooth Smart.

Ideal for both indoor and outdoor riding, this power meter seamlessly supports virtual training platforms like Zwift, TrainerRoad, and more.

Weighing only 9 grams more than a standard crank, this power meter adds no noticeable weight or Q-factor offset, preserving your pedalling efficiency. It's IPX7 waterproof rated and built to handle the rigours of intense training, poor weather, and high-performance racing.
