Fabrizio Dragoni, CEO and riding engineer, was stunned When Mulally had his incredible chainless ride and an year later when Aaron Gwin winning in Leogang: Chainless and started to work on a new riding scenario: chainless riding, maintaining the pedal stroke.

Chainless riding means flowing sensations, absence of pedal kickback, extremely good braking performance and more. OCHAIN active spider can remove or reduce pedal kickback, isolating transmission effects from rear suspension when needed.
