DVO looked through the clutter of the trail category to find clarity in what matters: performance and adjustability. The Diamond is the 140mm to 170mm do-it-all but cut-no-corners fork that caters to the aggressive rider that demands more. A precision-designed chassis and 35mm stanchions provide control in the movement of “ultimate shred” and increased tire clearance ensures reliability when the riding gets dirty. When going up to get down, this is the Diamond in the rough.

Six clicks of low-speed compression give quick access to firming up the fork for pedaling, opening up for descending, and mid-settings for everything in between. Over thirty clicks of High-Speed Compression give precise control for support on big hits. Shim stack-controlled rebound that is 100% dynamic, meaning the rebound is controlled based on the speed at which oil flows through the system. The fork will react to what you throw at it and be ready for what’s next. DVO's industry-exclusive OTT feature sets DVO products apart from anything else. It allows you to fine-tune how the initial stroke feels without any mid or end-stroke compromise. You really do get the best of both worlds.

Combining the stiff chassis characteristics with the exclusive features and damping design gives DVO forks a unique ride feel unlike anything else on the market.
