The Precision Pro Ride Ready comes pre-installed on a new Shimano 105 R7000 crankset.

3D Power Measurement

When you put force through your pedals or crank, it doesn’t just bend the crank – it twists and flexes in all three dimensions. 4iiii’s patented 3D power measurement system measures this multidimensional strain, so you can be confident that your unique pedal stroke is still measured accurately no matter your riding conditions.

Industry Leading Accuracy

4iiii’s +/- 1% accuracy isn’t just a claim, it’s been third-party tested and validated by leading scientists and the Locomotion Lab at the University of Colorado. You can plan your training, pacing, and racing with confidence knowing that your data is always going to be consistent. Don’t limit your potential with unreliable data.

Dual Channel ANT+ and Bluetooth Smart

4iiii Powermeters communicate their measurements over both the widely-used ANT+ and Bluetooth Smart radio standards, letting you read and record your power numbers on an enormous catalogue of head units, sports watches, smartphones, and computers.

3 Year Manufacturer’s Warranty

4iiii Powermeters are waterproof, durable, and designed to be accurate and precise even in the harshest conditions. Because of this, 4iiii are happy to offer an industry-leading 3-year warranty.
