4iiii Precision 3+ Pro Shimano Ultegra R8100 Dual Crank Powermeter - 172.5mm 52/36

4iiii Precision 3+ Pro Shimano Ultegra R8100 Dual Crank Powermeter – 172.5mm 52/36

Whether in training or racing, the Precision 3+ Pro Powermeter provides road cyclists as well as triathletes with the most accurate results. Through the use of two sensors, the left/right balance is also recorded, from which statements can be made about the evenness of the pedalling as well as the effectiveness of the torque. Equipped in this way, the Precision 3+ Pro powermeter becomes the ultimate training tool to help every rider achieve their personal goals.

What is new?

The + refers to the Apple Find My technology built into the power meter. If the power meter is not in use, the Find My feature is enabled. When the powermeter is added to the Find My app, it can be located via an iPhone, iPad, Mac or with the Find Items app on an Apple Watch.

Ride Ready. The delivery of the 4iiii powermeter sensors is already pre-mounted on the selected Shimano crankset for Hollowtech II bottom brackets. After installation at the bike* and connecting to the control unit or computer, you can immediately start recording power.

Advantages of 4iiii power meter systems

3D power measurement | If force is applied to the pedals and correspondingly to the crank, there is not only a bending of the crank arms in one dimension – twisting and deformation processes take place in all 3 directions. 4iiii’s patented 3D force measurement system measures this multi-dimensional loading, so no matter what the riding conditions or each rider’s unique pedal stroke, performance data is always accurately determined.

Gold standard in precision | The accuracy of 4iiii powermeters has been tested and validated by leading scientists at the Locomotion Lab at the University of Colorado. With +/- 1 % precision, training, pacing and racing can be reliably planned with the assurance of consistent data.

Dual-channel ANT+ & Bluetooth Smart | In order for riders to read and record their performance data from a wide catalog of devices, sports watches, smartphones and computers, 4iiii powermeters are capable of transmitting their measurement results using both the widely used ANT+ technology and the Bluetooth Smart wireless standard. Accordingly, 4iiii powermeters are also compatible with all popular indoor training applications, such as Zwift, TrainerRoad, TheSufferFest, Rouvy, etc.

Warranty & durability | 4iiii powermeter technology has been proven in the toughest tests around the globe – whether it’s sinking in the mud of Cross Country mountain bike races, on the rainy gravel roads of Strade Bianche, or even in the salty ocean spray of the America’s Cup. All 4iiii powermeters are certified to IPX7 protection rating and accordingly suitable for immersion in water up to one meter. Since 4iiii is confident in the durable design of its products, the manufacturer offers a 3-year warranty.

Scope of delivery:
