Dual-Sided Power Accuracy with Smart Tracking

Description

The 4iiii Dual Side Precision 3+ Pro Powermeter delivers the highly accurate power data riders expect, now enhanced with Apple Find My for added security. It helps you train smarter while giving you the confidence of always knowing your bike’s location whenever the powermeter is not in use.

Advanced Metrics for Smarter Training: With left/right balance, pedal smoothness and torque effectiveness, the Precision 3+ Pro provides the insight needed to refine your technique. Its ±1% accuracy and automatic terrain selector ensure consistent, reliable data whether you're racing, climbing, or doing structured interval work.

Long Battery Life for Long-Term Performance: Offering up to 550 hours of battery life, this powermeter is built for riders who train hard and often. It continuously transmits watts, cadence and calorie data to your preferred head unit, functioning as a seamless and dependable training partner on every ride.

Durable, Waterproof and Ready to Ride: The powermeter arrives ready for installation using the standard Shimano crank process, letting you start training immediately. 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.
