left hand crank. This crank will fit standard Hollowtech II bottom brackets.Left side 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 a great option for those just starting to train with power analysis
.4iiii Precision 3 power sensors are mounted on the inside of the crank, so 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 for compatibility.
Product Highlights
- 3D Accuracy: Not everyone has the perfect pedal stroke. With +/- 1% accuracy, the 4iiii Precision 3 power sensor crank uses 3 strain gauges to measure all the forces in your pedal stroke.
- Low profile: With an ultra low profile design, the Precision 3 is compatible with more bike 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 tired of 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 handle the toughest conditions.
- ANT+ & Bluetooth: Train indoors as well as outdoors. The Precision 3 power sensor is both ANT+ and Bluetooth Low Energy (BLE) compatible, so you can use it on your favorite meter and indoor training app.
- 3 Year Warranty: a lot can happen in 3 years. You probably won't need to use it, but it's reassuring to know that all 4iiii power sensors are covered by a 3-year warranty.
