4iiii Precision 3 Power Meter Shimano Ultegra 8100

Trusted Precision

The 4iiii Precision 3 Power Meter is engineered to raise the bar on existing expectations for single-sided power meters—with power measurement accuracy at +/- 1%, long battery life, and long-term durability to help you get the most from your rides. With power measuring pods installed into factory crank arms, the Precision 3 doesn’t compromise performance or compatibility. This power meter is the only single-sided power meter to use 3 strain gauges, allowing it to measure all power output forces (between 0-4,000 watts), and offer more accurate readings than many power meters on the market. The Precision 3 adds only 9 grams to the weight of the factory crankarm, features an IPx7 waterproof rating, and is backed by a 3-year manufacturer warranty for precision you can count on.
