4iiii Innovations has announced a new partnership with Specialized Bicycle Components. As a result, the 3D, lightweight, waterproof powermeter technology that powered Bora-hansgrohe and Quick-Step Floors for two years on the UCI World Tour is now built into the new Specialized Power Cranks.
Through its Human Performance Lab at the Specialized Win Tunnel, Specialized developed a unique testing protocol using a custom cycling treadmill. Specialized tested various riders, conditions and powermeters, verifying accuracy in real-world conditions. S-Works Power Cranks including 4iiii powermeter technology reportedly tested more accurately than others on the market, with accuracy within 1.5% under all real-world riding scenarios. This accuracy has been independently validated by the Locomotion Laboratory at the University of Colorado, Boulder.
Specialized has therefore chosen 4iiii to be the technology partner for its complete line of Power Cranks. As a result, S-Works, Shimano Dura-Ace, Ultegra and 105 Power Cranks will be available in various dual and single-side aftermarket configurations.
According to Specialized, the partnership marks the first time that powermeter technology is on a dual-sided carbon crank. Specialized is launching the cranks as original equipment on its flagship S-Works Tarmac Disc.
“Our collaboration has led to incredible real-world accuracy and the first commercially available direct measurement dual-sided powermeter on a carbon crank,” said Mark Cote, Head of Marketing and Innovation at Specialized.
“We’re proud to be partnering with Specialized,” said 4iiii CEO Kip Fyfe. “They share our commitment to innovate and build products that grow cyclists’ passion for riding.”
Specialized World Tour road teams Bora-hansgrohe and Quick-Step Floors have been testing 4iiii powermeter technology in competition for the last two seasons, winning two UCI World Road Championships, multiple Grand Tour stage victories, and many more World Tour and Continental results.
