The bicycle drivetrain has remained true to its roots for over a century — until now. Dramatic departures from the derailleur-based chain drive system have cropped up in recent years, perhaps offering a peek at what the future holds for bicycle development.
Classified Cycling CTO Roëll van Druten reveals how the Powershift system allows front derailleur-type shifts without a front derailleur. And Driven Technologies (a CeramicSpeed company) CTO and project pioneer Jason Smith walks us through what a chainless drivetrain looks like now, and how it will change the overall design of the bikes we buy in the near future.
