4iiii Precision - Ride with Power

Used to pace attacks up the Alpe D’Huez in the Tour de France and hammer on the Queen K during the Ironman World Championships, the PRECISION power meter delivers industry-leading accuracy and reliability when you need it most. Through 4iiii's patented 3D strain gauge technology, you have the assurance knowing that the data you depend on will help lead you to your own Yellow Jersey.

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. [Details]

Features:

  • GOLD STANDARD IN ACCURACY: 4iiii power meters have had their gold-standard /- 1% accuracy independently verified by leading scientists at the Locomotion Lab at the University of Colorado. This lets you plan your training, pacing, and racing with confidence, knowing that your equipment measures your actual power output. .
  • 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, sports watches, smartphones, and computers.
  • 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.
  • 3 YEAR WARRANTY: 4iiii powermeters are waterproof, durable, and designed to be accurate and precise even in the harshest conditions. Because of this, we are happy to offer an industry-leading 3-year warranty.
