Enduro / Freeride


170mm - 180mm



Knolly’s most notorious model has eluded proper classification since its launch back in 2008…. and that’s just the way we like it. Whether you're into freeride, shuttle DH, or if you only ride Park…the Delirium is the rig that will take you to the next level, and in massive style. 

Versatility. This has been the cornerstone of the Delirium concept since day one. Striking the balance between ‘tough as nails’ and ‘playful’ on the trail is a tall order. The Delirium delivers. The newest version of this shape shifter allows the pilot to configure this model in many different ways, including adjustable geometry, and it's cleared for take-off with all dual crown forks.


FOURby4 Suspension 

Yes, you see an extra linkage here. This is the secret sauce in the Fourby4 design. It allows us to decouple the performance aspects of the rear suspension, which means we can fine-tune each bike to match its intended purpose. Put simply - the lower linkage controls the rear wheel axle path, and the upper linkage controls the shock progression.
