4iiii Precision Pro Dual Shimano 105 R7000 Powermeter

Used to pace attacks up the Alpe D’Huez in the Tour de France and to hammer on the Queen K during the Ironman World Championships, the PRECISION PRO Powermeter delivers industry leading accuracy and reliability when you need it most. Through our patented 3D Strain Gauge technology, you can be assured that the data you depend on will help lead you to your own Yellow Jersey.

Features

• 4iiii makes the lightest power meter on the market. We’re committed to helping you get faster, one gram at a time.
• A dual power meter measures the power from each individual leg to calculate your total power output.
• Not everyone has the perfect pedal stroke. With +/- 1% accuracy, 4iiii is the only crank-based power meter to use 3 strain gauges to measure all forces in your pedal stroke.
• Get more data like pedal smoothness and torque effectiveness to analyze and optimize your pedal stroke.
• If the weather or climate make riding outdoors tough, your 4iiii power meter can be used with all popular indoor-training apps, such as Zwift, TrainerRoad, Wahoo SYSTM, Rouvy, and more.
