4iiii PRECISION 3 Shimano DURA-ACE 9200 Power Meter

Introducing the all new 4iiii PRECISION 3 Shimano DURA-ACE 9200 Power Meter. This power meter features a 4iiii PRECISION 3 sensor on a Shimano left side 12-speed DA 9200 crank arm. The result is one of the lightest, most affordable and most accurate power meters available.

The PRECISION determines your total power based on the force that is generated by your left leg. This left-only design allows for a power meter that is lightweight and easy to install. Specifically, the power meter adds only 9 grams to your crank arm and is installed in about 10 minutes.

The 4iiii power meter is accurate to +/- 1.0% and comes with a full 3-year warranty. In addition, it is compatible with both ANT+ and Bluetooth SMART devices. This means you can use it with your favorite bicycle computer, watch or smart phone.

 

Key Product Details

Compatibility:

Power Measurement:

This 4iiii power meter measures left leg power and doubles the value to account for both legs (assumes both legs are generating the same force).

Advice From Our Staff:

4iiii left side crank arms are some of our best-selling units. They work with most Shimano cranksets, are affordable and easy to install. The one consideration is they only measure left leg power compared to some other power meters that measure power from both legs (those versions usually cost more however).

 

Options For This Power Meter

  • Crank arm lengths: 165 mm | 170 mm | 172.5 mm | 175 mm

4iiii PRECISION DURA-ACE 9200 Compatibility

Crankset: This 4iiii power meter is compatible with Shimano DURA-ACE 9200 cranksets.

Please note, the power meter can also be installed other Shimano road cranksets, as long as they use Shimano's Hollowtech II interface. These cranksets can easily be identified by the two opposing pinch bolts that are used to secure the left side crank arm. Please see the image below and contact us if you have any questions on compatibility.Shimano Hollowtech II Left Crank Arm

Check Frame Clearance: Crank-arm based power meters attach a sensor on the inside of the left crank arm. On some bikes, there is not enough room between the left crank arm and the chainstay for the sensor to clear the frame. Therefore, you should make sure you have at least 8 mm of clearance for the PRECISION 3. Also, make sure that you don't have a bottom bracket mounted rear brake (used on some aero and TT bikes). The important area to measure is right in the middle of the crank arm. Please refer to the image below.

If you find that your clearance is close but not quite sufficient, what many people will do is simply install a 1 or 2 mm bottom bracket spacer (between the left crank arm and the frame). This should provide you with the clearance you need.
