4iiii Precision 2.0 3D Shimano Ultegra 6800 Power Meter

Riding with a power meter can have a huge positive impact on your efficiency, strength and in turn, race results. The 4iiii Precision 2.0 3D Power Meter comes attached to a Shimano Ultegra 6800 left crank arm, making for easy installation and maintenance.

The 4iiii app allows you to monitor the units battery life, ensuring uninterrupted training, however, with over 100 riding hours this needn't be a regular occurrence. Adding only 9 grams to your existing Ultegra setup, this sleek upgrade offers countless benefits without any real weight penalty, perfect for those chasing every incremental gain.

Utilising 4iiii's Patent Pending 3D power meter technology, the Tri-axial strain is measured through the left crank arm. This provides highly accurate data, with only a +/- 1% margin of error, these are results you can depend on. Cadence is measured too, removing the need for an additional sensor. This, combined with the robust, durable design, ensures a simple, clean and good value for money solution to measuring your power outputs.

The Precision 2.0 Power Meter is compatible with fitness apps including Strava and Wahoo Fitness, and Garmin, Wahoo and Cateye head units plus others supporting Bluetooth Smart and ANT+.
