ZWOLLE, Netherlands (BRAIN) — NuVinci has upgraded its Harmony automatic shifting system with more robust hardware components and new sensors to improve the accuracy, reliability and longevity of the system.
“In the process of designing the new version of Harmony, NuVinci Cycling, a division of Fallbrook Technologies Inc., set an aggressive goal of zero failures for the new key components. As a result, the life expectancy of the new sensors, compared to the old ones, increased by an order of magnitude,” NuVinci stated.
“We completed all pre-launch product reliability testing with no failures, and were not able to induce any failures in the new sensors in any of our tests,” said Brian Sweet, manager of engineering design at Fallbrook.
Claimed benefits of the system include continuous step-less and automatic shifting, effortless shifting under load, greater gear ratio range than many conventional shifting systems, as well as comfortable pedaling at the rider’s desired cadence.
A video with instructions on how to install the new Harmony interface is available on NuVinci’s website.
