The Ochain Active Spider is a hot new technology that disengages the chainring when not under load to create a 'chainless' ride feel.

 Chainless riding means flowing sensations, absent pedal kickback, extremely good braking performance and it removes negative effects of pedal weight from your suspension, enabling you to ride faster and smoother. It takes the edge off sharp hits, particularly on more technical terrain.

Just look at the World Cup DH and Enduro results to see how many top riders are running these, they're the real deal.

          Smooth Riding

          I have found that the ochain makes a noticeable difference to how my bike (Nukeproof Dissent 27.5) feels on rough trails. After riding for a week in Morzine it feels like it glides over braking bumps and just helps to smooth out the rough stuff. The only reason I didn’t give 5 stars is because it was quite a faff to fit.
