One final highlight is that it boasts up to 800 hours of battery life from its long-lasting coin cell battery.

Shimano XTR M9100 Crank Arm
27 years of development and Shimano is right back to where it all started, introducing the ultimate MTB race components. Designed to meet the highest level competitive mountain bike racing needs with a second to none performance and experience. The XTR M9100 Series brings the most versatile groupset for XC, enduro and marathon racing.

ANT+ and Bluetooth Compatible
4iiii PRECISION 3 power meters use both the ANT+ PWR and Bluetooth Smart Cycling Power Service standards, which makes them compatible with nearly every headunit, smartphone, or computer you wish to connect to. Check your recording device documentation for ANT+ PWR or Bluetooth Smart (also called BLE, BTLE, or BT4.0) Cycling Power Service capability.

Indoor Training
If the weather or climate makes riding outdoors tough, your 4iiii PRECISION 3 powermeter can be used with all popular indoor-training apps, such as Zwift, TrainerRoad, Wahoo SYSTM, Rouvy, and more. Simply use your favorite app's connection procedure over ANT+ or Bluetooth Smart, put your bike on a trainer, and get riding.

4iiii Warranty
Ridden through rain storms at Strade Bianche, mud-filled cross country mountain bike races, and even tested amidst the salt spray of the ocean on Oracle Team USA's America's Cup competitors, you can be assured that your 4iiii Powermeter will be as tough as you are and is backed with an industry-leading 4iiii 3-year warranty. All 4iiii Powermeters are IPX7-rated for water immersion up to one meter and backed with an industry-leading 3-year warranty.

Accuracy in 3D: 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.

Ultra 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 when your power meter has turned on, performed a successful Zero-offset, or has a low battery. Although, don’t expect to see that low battery indicator for a while!

Waterproof: Based in the foothills of the Canadian Rockies, we were tired of training tools not designed to work in our tough environment. With an IPX7 waterproof rating you can be assured that your power meter can handle the toughest conditions.

ANT+ & Bluetooth: Get the same numbers training inside and outside. The PRECISION 3 Powermeter is both ANT+ and BLE compatible so you can use it on your preferred head unit and favorite 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 Powermeters are backed by an industry leading 3-year warranty.

In The Box: Once your ride-ready PRECISION 3 powermeter arrives, it just needs to be installed on your bike using the standard Shimano crank installation process. Connect a headunit or computer, and you can start riding with power!
