The radical new track drivetrain design by New Motion Labs - which uses a wider tooth profile and a sprocket with half as many teeth in order to improve efficiency and reduce wear - didn't make it to the Izu Velodrome for the Tokyo Olympics, but it is now fitted to a bike and on show at Eurobike. 

Creators New Motion Labs are calling the system the 'world's fastest cycle drivetrain' for competitive cycling, they're showing off both the Evolve Track and Evolve Track 8mm drivetrains at the trade show in Friedrichshafen, as well as an e-cargo bike version designed to meet the very different needs of utility riders.

After winning the 2019 National Single-Speed Cross-Country Mountain Biking Championships and claiming the plushie unicorn (true story), Stefan swapped the flat-bars for drop-bars and has never looked back. 

Since then, he’s earnt his 2ⁿᵈ cat racing licence in his first season racing as a third, completed the South Downs Double in under 20 hours and Everested in under 12.

But his favourite rides are multiday bikepacking trips, with all the huge amount of cycling tech and long days spent exploring new roads and trails - as well as histories and cultures. Most recently, he’s spent two weeks riding from Budapest into the mountains of Slovakia
