The PRECISION Power Meter delivers industry leading accuracy and reliability when you need it most. Through PRECISION's patented 3D Strain Gauge Technology, rest assured the data you depend on will help lead you to victory.

Packaged into a durable lightweight design and compatible with ANT+ and Bluetooth Smart Head Units, PRECISION will help you train harder and smarter.

A Ride Ready PRECISION includes and comes preinstalled on a brand-new Shimano Crank Arm of your choice. These crank arms will fit bottom brackets using the Hollowtech II interface.

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 3 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
Our +/- 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. Want to learn more?

DUAL-CHANNEL ANT+ & BLUETOOTH SMART
4iiii Power Meters 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 catalog of Head Units, sport watches, smartphones, and computers.
