4iiii Innovations has a new version of its left-side-crank-based power meter, the Precision 2.0. 4iiii calls it the ” the industry’s first 3D crank based power meter,” as it can measure bend, shear and axial forces on the crank, the company claims.
“Capturing all forces on the cranks in three dimensions moves traditional power monitoring a quantum step ahead to improve accuracy and lay the foundation for new features,” 4iiii CEO Kip Fyfe said in a press release. “This increase in power data quality and quantity is key to empowering coaches and cyclists with the detailed feedback they need to optimize their training and racing.”
It is unclear if or how this 3D data will be displayed beyond 4iiii’s app, as Garmin Edge and other computers don’t have such fields. The company didn’t immediately respond to questions about this.
Much like a Stages meter, the new Precision 2.0 features a smaller pod than the company’s first meter on the inside of the left crank arm. The company says the pod weighs a mere 9g.
There are two ways to buy: send the company your alloy crank, or buy one from them. Sending in your own crank arm costs $399. You can buy Shimano 105 for $399, Ultegra or XT for $499, and Dura-Ace or XTR for $599. UK pricing was not immediately available.
The 4iiii Precision 2.0 is not available for carbon cranks. Alloy cranks that you can send in include Shimano 105, Ultegra, Dura-Ace, XT and XTR; Cannondale Hollowgram; SRAM Rival OCT; and FSA Energy.
