4iiii PRECISION 3+ PRO Shimano DURA-ACE 9200 Dual-Sided Power Meter
The 4iiii PRECISION 3+ PRO Shimano DURA-ACE 9200 Dual-Sided Power Meter combines 4iiii’s dual-sided power sensors with Shimano’s top-end DURA-ACE 9200 crankset. The result is an accurate, stiff, lightweight power meter that measures power from both legs. In addition, with a power sensor located separately on both crank arms, the power meter can measure forces generated by each leg individually.
This 4iiii power meter is accurate to +/- 1.0%, features dual ANT+ and Bluetooth SMART and is extremely lightweight, adding only 40 grams to the Shimano DA 9200 crankset. The 4iiii PRECISION 3+ uses a coin cell 2032 battery with an 550-hour battery life.
Key Product Details
Compatibility:
This power meter is compatible with 2×12 road drivetrains and 24 mm Shimano bottom brackets. Most customers that buy it already have a Shimano DA9200 crankset on their bike and therefore, it’s an easy swap. However, it can be used on any road bike as long as its 2×12 with a 24 mm bottom bracket. See Compatibility tab for more information.
Power Measurement:
This 4iiii power meter has a power sensor on both crank arms and measures power from both legs. It is also able to measure your left vs. right leg power.

Advice From Our Staff:
This is a great option for customers with a Shimano DA9200 drivetrain that want to keep an OEM DA9200 crankset on their bike but add power. It’s lightweight, stiff and measures power from both legs. We also like that fact that this crankset measures power from both legs and has a 3-year warranty, which is longer than most power meters.

Compatibility
Bottom Bracket: This power meter is compatible with 2x12 road drivetrains and 24 mm Shimano bottom brackets. Most customers that buy it already have a Shimano DA9200 crankset on their bike and therefore, it's an easy swap. However, it can be used on any road bike as long as its 2x12 with a 24 mm bottom bracket.
Check Frame Clearance: Crank-arm based power meters like this one 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 10 mm of clearance between the left crank arm and the chainstay - and 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 you have around 7-9 mm of clearance, what many people will do is simply install a 1 or 2 mm bottom bracket spacer (between the left crank arm and the frame), which will give them the clearance they need.
