4iiii Precision LH Power Meter Shimano GRX NDS RX810 170mm

The 4iiii Precision LH Power Meter is an all-new concept from cycling disruptors 4iiii! They offer precision power meters pre-installed on the left-sided Shimano crank arm of your choice. Featuring 4iiii's patented Precision 3D Strain Gauge technology, three aspects of your pedal stroke are measured to provide you with the accurate data you've been dreaming of!

Before its release, the 4iiii Precision LH Power Meter was tested during extreme events: attacking the Alpe D'Huez in the Tour de France and delivering the precision needed during the Queen K Ironman World Championships. Not only does this mean you can trust the data, but you can use it to continuously improve your performance.

The 4iiii Precision LH Power Meter has been designed to be lightweight yet durable, only adding a minuscule 9g to the weight of the crank arm it's installed on. With both ANT+ and Bluetooth support, the Precision Power Meter can be paired to any modern smart head unit to provide you with the data you want when training or racing.

With the 4iiii Precision LH Power Meter, don't settle for second best, achieve your own yellow jersey!

Great Service, Products and Delivery

By: David Jones on 10 April 2025
A great store that you can trust. Prepurchase, I asked some questions via email, and they were answered promptly. When I purchased online, I had a tracking number within the hour. The item was delivered in a timely manner in new condition. The item that I purchased, a power meter, was easy to instal and has worked like all my other power meters in the first 500km of use. A very happy customer who would recommend "The Bicycle Depot" to anyone looking for quality cycling products at great prices. I would give Tom and his crew 10 out of 10.
