4iiii Power sensor Precision-GEN3-Ultegra-R8100-NDS

Shimano Ultégra 12-speed 52/36 power sensor crankset

Offering up to 800 hours of autonomy, +/- 1% accuracy and backed by the legendary 4iiii, the Precision 3 power sensor will be your trusted training tool for years to come. This 4iiii Precision "Ride Ready" power sensor is pre-installed on an all-new Shimano Ultegra R8100 left-hand crank. This crank will fit standard Hollowtech II bottom brackets.

A left crank with integrated power sensor measures the power created by your left leg and multiplies it by two to give you your total power. A left-side power sensor is an excellent option for those just starting to train with power analysis.

As 4iiii Precision 3 power sensors are mounted on the inside of the crank, make sure you have enough space between your crank and frame for the sensor to fit properly. Print and use the guide below to check your frame's compatibility.

PRODUCT ADVANTAGES :

• 3D precision: not everyone has the perfect pedal stroke. With an accuracy of +/- 1%, the 4iiii Precision 3 power sensor crank uses 3 strain gauges to measure all the forces of your pedal stroke.
• Low profile: with a discreet ultra design, the Precision 3 is compatible with more bicycle frames than ever before.
• Indicator light: at a glance, you can now see the status of your sensor (on, Zero-offset, low battery). But don't expect to see that low battery indicator for a while!
• Waterproof: based in the foothills of the Canadian Rockies, the designers at 4iiii were fed up with analysis tools that weren't designed to work in their harsh environment. With an IPX7 waterproof rating, you can rest assured that your power meter can withstand the harshest conditions.
• ANT+ & Bluetooth: train indoors as well as outdoors. The Precision 3 power sensor is both compatible ANT+ and Bluetooth Low Energy (BLE), so you can use it on your favorite computer and indoor training app.
• A lot can happen in 3 years. You probably won't need to use it, but it's reassuring to know that tous 4iiii power sensors are covered by a .
