4iiii Precision Shimano XT M8100 left crank with power meter

Used to pace attacks up the Alpe D’Huez in the Tour de France and to hammer on the Queen K during the Ironman World Championships, the PRECISION Powermeter delivers industry leading accuracy and reliability when you need it most. Through our patented 3D Strain Gauge technology, you can be assured that the data you depend on will help lead you to your own Yellow Jersey.

Packaged into a durable lightweight design and compatible with ANT+ and Bluetooth Smart headunits, PRECISION will help you train harder and smarter.

A Ride Ready PRECISION includes and comes preinstalled on a brand-new Shimano crank arm of your choice. These crank arms will fit bottom brackets using the Hollowtech II interface.

In The Box:
- Once your ride-ready PRECISION 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!

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.

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.
