The 4iiii Precision 3+ Pro Dual Sided Power Meter - Dura-Ace R9200 gives you true bilateral power measurement built directly into the crank arms of one of road cycling's most respected drivetrains. By mounting strain gauge technology to both the left and right arms of the R9200 crankset, it captures independent left and right power data — giving you an accurate picture of your output and any imbalances between legs that a single-sided meter would miss.

The Precision 3+ Pro transmits over ANT+ and Bluetooth simultaneously, so it pairs with head units, smartphones, and training platforms without fuss. Battery life is rated to deliver extended training and racing use before needing attention, and the unit is designed to be low-profile enough that it won't interfere with your existing chainline or front derailleur clearance on the R9200 system.
