Description

Experience a new level of training insight with the 4iiii Precision 3+ left crank power meter. Designed for riders who demand accurate data, this crank delivers real-time power numbers from the non-drive side, helping you fine-tune effort on every ride. The 172.5mm length fits a wide range of frames, while the sleek black finish blends seamlessly with GRX groupsets. By measuring power directly at the crank, you get a clear picture of pedal dynamics, allowing smarter pacing, better cadence control, and more effective interval work. Whether you're tackling steep climbs or sprinting on flats, the Precision 3+ provides consistent, reliable metrics to guide your performance improvements. Install it on your bike and start collecting the data you need to train smarter, race faster, and track progress over time.

Key Features

Left-side power measurement captures pedal force without affecting drivetrain balance, giving you true power data for smarter training decisions.

Compatible with GRX components, the crank integrates smoothly into existing setups while maintaining the sleek black aesthetic.

172.5mm spindle length fits many frame standards, ensuring a hassle-free installation for a wide range of bicycles.

Built by 4iiii, a trusted name in cycling power technology, offering confidence in accuracy and durability.

Non-drive side (NDS) design eliminates the need for additional sensors on the drive side, simplifying maintenance and reducing wear.
