Frame/Bike Compatibility

Because 4iiii PRECISION powermeters are mounted on the inside of your crank, there needs to be enough space between your crank and the frame for the pod to fit. Print and use the clearance guides below to check your frame.
Tip: Often a right-side power meter installation has more clearance and may be suitable if your bike does not appear to have enough space for a left-side installation.
Tip: 4iiii PRECISION 3 powermeters have a much lower profile and may fit where a PRECISION does not.

Communication Compatibility

4iiii PRECISION 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.
Tip: A 4iiii Viiiiva can be used to record your workouts along with your heart rate.

Crank Compatibility

A 4iiii PRECISION powermeter is available ready to ride on any of the crankset configurations listed below. If your desired crankset isn't listed, we may have other products that are compatible. Use the interactive tool below to discover them

3D POWER MEASUREMENT

When you put force through your pedals or crank, it doesn't just bend the crank - it twists and flexes in all 3 dimensions. 4iiii's patented 3D power measurement system measures this multidimensional strain, so you can be confident that your unique pedal stroke is still measured accurately no matter your riding conditions. 

INDUSTRY LEADING ACCURACY

Our +/- 1% accuracy isn’t just a claim, it’s been third party tested and validated by leading scientists and the Locomotion Lab at the University of Colorado. You can plan your training, pacing, and racing with confidence knowing that your data is always going to be consistent. Don’t limit your potential with unreliable data. Want to learn more?

DUAL-CHANNEL ANT+ & BLUETOOTH SMART

4iiii Powermeters communicate their measurements over both the widely-used ANT+ and Bluetooth Smart radio standards, letting you read and record your power numbers on an enormous catalog of headunits, sportswatches, smartphones, and computers.
