Thinking about upgrading to power? The 4iii PRECISION 3+ 105 R7000 Left Arm Power Meter is a great choice. Available from 165mm to 175mm, so you can find the best fit for you, this power crank will accurately translate your power output to your head unit of choice. Find your power zones and train smarter with the Precision 3+ 105 R7000 Left Arm Power Meter. With up to 800 hours of battery life, an automatic terrain selector, +/-1% accuracy, and backed by 4iiii's industry-leading 3-year warranty, the Precision 3+ Powermeter is a trusted tool for recording power with superb accuracy. While you ride, your PRECISION 3+ Powermeter will transmit watts, cadence, and calories to your bike computer. When the power meter is not in use, Find My is enabled and allows you to see its location on a map. You can add your power meter to the Find My app and locate it on an iPhone, iPad, Mac or using the Find Items app on an Apple Watch.


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 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.


Offering the peace of mind in knowing where your power meter is.

With 800 hours of battery life, you won’t have to worry about changing your battery for years to come.

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.

Detects the terrain you’re riding on for more responsive cadence and power feedback/data. Ride the roads less travelled with confidence.

With an ultra low profile design, the PRECISION 3+ is compatible with more bike frames than ever before.

At only 9 grams the Precision Powermeter weighs about the same as a sip from your water bottle. 4iiii's goal is to help you get faster, not to slow you down.

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.

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 meters are backed by an industry leading 3-year warranty.
