- Description
Get ready to elevate your riding experience with the new PRECISION 3+ PRO Powermeter with Apple Find My. Delivering the same reliable and highly accurate power data you’ve come to expect from 4iiii, while enjoying the peace of mind that comes with knowing the location of your bike.
With advanced metrics such as left/right balance, pedal smoothness and torque effectiveness, the PRECISION 3+ PRO Powermeter provides the data you need for training and racing. With up to 550 hours of battery life, an automatic terrain selector, +/-1% accuracy and backed by our industry-leading 3-year warranty, the PRECISION 3+ PRO Powermeter will be your trusted tool for years to come.
HOW DOES IT WORK?
The PRECISION 3+ Power Meter is so much more than a power meter. It’s a training partner that gives you peace of mind. During your ride, the PRECISION 3+ Power Meter sends power, cadence, and calorie burn data to your favorite bike computer. When not in use, Find My activates to show you your bike’s location on a map. Add your power meter to the Find My app to locate it on iPhone, iPad, Mac, or the Find Items app on your Apple Watch.
IN THE BOX
Once your ride-ready PRECISION 3+ PRO Powermeter arrives, it just needs to be installed on your bike using the standard Shimano crank installation process. Connect a head unit or computer, and you can start riding with power. Connect to the Find My app with your iPhone or iPad to start tracking your power meter.
WARRANTY & DURABILITY
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 power meter will be as tough as you are and is backed with an industry leading 3-year warranty. All 4iiii power meters are IPX7-rated for water immersion up to one meter and backed with an industry-leading 3-year warranty.
INDOOR RIDING
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. Simply use your favourite app’s connection procedure over ANT+ or Bluetooth Smart, put your bike on a trainer, and get riding!
