Classified releases test data proving over 99% hub efficiency

October 3, 2023

Highest accuracy testing shows that the Powershift hub is over 99% efficient in both the 1:1 and 0.7 gear ratios

Antwerp / Eindhoven /ENDURANCE SPORTSWIRE/ – For the first time since introducing the Powershift hub, Belgian technology company Classified has released key measuring data which proves the efficiency of the Powershift hub.

Classified CTO Roëll van Druten explained the background of the testing:

“Drawing on our experience in the automotive industry, Classified has tested the Powershift hub to the highest standards, using a test rig specifically designed to measure power loss with a maximum error of 0.1%. The results of these tests show that the hub is 99.8% efficient in the 1:1 ratio, the same as a DT Swiss 240 hub (industry standard) measured on the same test-rig, and 99.2% efficient in the 0.7 ratio, making Classified’s hub the most efficient internal geared hub ever created.”

Van Druten is also clear to point out the proven efficiency data is just a part of the benefits that Classified’s Powershift Technology can offer:

“Next to the overall efficiency increases, one the biggest advantages are the lightning fast shifting under full load and ultimate control of gearing choices.”

2023 has seen Classified make its mark on the professional racing scene as well, with Victor Campenaerts racing Powershift Technology at World Tour level, Kyle Smith racing the technology to victory in Ironman events and Rob Britton winning the ultra-distance gravel race Badlands.

With the release of specific mountain bike and triathlon products in the summer of 2023, Classified is now present in the four main disciplines of cycling – road, gravel, MTB, and Triathlon/TT.
