4iiii Precision 3+ Pro Dual Sided Power Meter - Ultegra R8100 Info
The 4iiii Precision 3+ Pro Dual Sided Power Meter - Ultegra R8100 measures power from both sides of your pedal stroke, giving you the left/right balance data that a single-sided unit simply cannot provide. Built around the proven Shimano Ultegra R8100 crankset, it pairs a factory-level crank with 4iiii's strain gauge technology — so you're not compromising on drivetrain quality to gain training data.
Dual-sided measurement means every watt is accounted for, which matters when you're building a training block, chasing a functional threshold power test, or trying to identify and correct leg imbalances over time. The Precision 3+ Pro transmits via ANT+ and Bluetooth simultaneously, so it works with your head unit and your training app at the same time without any pairing compromises.
