4iiii Precision 3+ – Shimano Ultegra R8100 – Left Side

Professional Precision Meets Smart Tracking: The Ultimate Training Tool

The 4iiii Precision 3+ is more than just a power meter; it’s a sophisticated training partner designed for the modern cyclist. This left-side power meter comes pre-installed on a brand-new Shimano Ultegra R8100 crank arm, offering a seamless "plug-and-play" installation that maintains the factory aesthetics and shifting performance of your 12-speed drivetrain.

The "3+" generation introduces the groundbreaking Apple Find My integration, allowing you to track your bike's location via your iPhone—providing peace of mind both on and off the road.

Key Features

• Ultra-Low Profile Design: The thinnest power meter on the market. With its sleek, slim casing, it is compatible with almost every bike frame, even those with tight chainstay clearances.

• Apple Find My Integration: A world-first for power meters. If your bike goes missing, you can locate it using the massive Apple "Find My" network on your Apple devices.

• Unmatched Battery Life: Boasting a massive 800 hours of battery life from a single CR2032 coin cell—nearly double the industry standard.

• ±1% Accuracy: 4iiii uses patented 3D strain gauge technology to deliver consistent, laboratory-grade data regardless of riding conditions.

• Active Temperature Compensation: Ensures that your power readings remain accurate even during rapid temperature shifts (e.g., descending from a mountain pass).

• Dual Connectivity: Supports both ANT+ and Bluetooth Smart, allowing you to connect to your head unit (Garmin, Wahoo, Hammerhead) and training apps like Zwift simultaneously.

• IPX7 Waterproofing: Built to survive the worst weather, from rain-soaked spring classics to high-pressure bike washes.

Technical Specifications

FAQ - Frequently Asked Questions

• Will it fit my frame?

  The Precision 3+ is designed to be extremely thin. If you can fit a AAA battery between your current left crank arm and the frame, this power meter will fit perfectly.

• Is it easy to install?

  Yes. It replaces your existing left Ultegra arm. Simply remove the two pinch bolts, swap the arms, and tighten to Shimano specifications (12-14Nm).

• Does it work with 11-speed Ultegra?

  While the R8100 is designed for 12-speed, the crank arm interface (Hollowtech II) is the same. However, for perfect aesthetic and Q-factor matching, it is best paired with an R8100 or R9200 drivetrain.
