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.
