Product Description

The latest gem from DVO packs all the performance of a dh fork into a 130-160mm trail fork. With 35mm stanchions, an industry first compression bladder cartridge, dynamic tunability, and our off the top adjustable negative spring make this the ultimate trail and enduro race fork.

Key Features:
  • Quick range low speed compression: With a quick turn of the knob, the low speed circuit is restricted providing a nice platform for climbing.
  • High speed compression adjust: Loader style compression provides easy access to the piston & shims for serious tuning
  • OTT off the top: This exclusive & proven DVO design trickles down from the emerald to deliver precise air spring tuning with a turn of knob.
  • Closed cartridge bladder system: Just like the jade rear shock, the bladder is compressed rather than expanded offering incredible small bump sensitivity.
  • Dynamic Rebound Adjust: Via Piston and Shims
  • 15mm QR Tapered Axle: Light, stiff and durable
  • Integrated Fender: Seamless integrated design prevents mud and debris from accumulating in the webbing.


  • Travel 130-160mm via spacers
  • Crown Offset 27.5" = 44mm Offset, 29" = 51mm Offset
  • Axle to crown 27.5 = 555mm at 160mm, 29 = 572mm at 160mm
  • Stanchions 35mm Tapered Alloy
  • Wheel Size 27.5" & 29"
  • Axle 15 x 100mm QR
  • Weight 2100g
  • Steerer Options Tapered Alloy
  • Lowers Magnesium, Disc only

    Suspension Forks Guide


    Suspension Forks Guide

    A new suspension fork is one of the most noticeable and worthy upgrades you can make to your mountain bike. A higher quality fork will be able to deal with more difficult terrain, remaining composed on the trail and keeping your wheel in contact with the ground. This gives more grip, and therefore a more confidence inspiring ride.


    The amount of distance the fork can move vertically is referred to as travel (shown in mm). The frame manufacturer will have designed the bike around a certain amount of travel. The general rule is to stay with this. Increasing or decreasing the fork travel can result in the geometry being severely compromised, making the bike handle worse than intended and putting more stress on the headtube structure.

    *Changing fork travel can void frame warranty from the manufacturer, please check with the manufacturer before any travel increase/decrease.

    As fork travel increases so can flex, to combat this a triple clamp design is used for forks with over 180mm of travel. The hub plus the two crowns creates a triple clamp. The forks are for DH use.

    A triple clamp DH fork, travel is measured from the lower crown to the top of the fork lower legs


    The distance the axle is offset from the steering axis. This directly affects the “Trail”. Trail is the distance between the contact point of the tyre and where the steering axis hits the floor. The shorter the offset the longer the trail and vice versa. Wheelsize also affects trail. Larger wheels have a longer trail. With the popularity of 29er MTB’s, there is often an offset choice to be made.


    The most common offset for a 29er fork is 51mm, however, fork manufacturers offer shorter offsets to increase trail.

    Without going too far into things, a longer trail (Shorter offset) will increase stability at speed in a similar way to a slacker head angle. A longer offset (shorter trail) will sharpen the bikes handling at low speed but might not feel quite as stable at high speed. Often it is best to stick with whatever offset was chosen by the manufacturer to work with the geometry of the frame.


    Spring type

    Although the vast majority of forks are air sprung, some entry level and a handful of high-end forks use coil springs.

    Air sprung



    • Lightweight
    • Less plush than coil
    • Easily adjustable
    • More internals than coil to maintain
    • Easy setup
    • Less small bump sensitivity

    Coil sprung



    • Increases traction
    • Less adjustable
    • More supple and plush
    • Not as easy to set up as air
    • Ground hugging feel
    • Heavier than air shocks


    Compression damping controls how the fork moves through its travel. Almost every fork will have some form of compression adjustment. On entry level forks a lockout might be a feature, the more the fork costs the more adjustment is available. Forks might have multiple compression options, for example, a “Climb, Trail, descend” or “open, medium, firm” dial, while top-line forks have precise control of both high and low-speed compression.


    Adjusts how fast the fork returns to full extension or sag point. Rebound adjustment can be found on entry level shocks. Top-line shocks will have separate high and low-speed rebound adjustment controlling how the fork reacts after high and low-speed compressions.

    Jargon Buster

    Compression – Controlling how the suspension moves through the available travel.

    Head Angle – The angle of the fork to the floor, this will range in degrees from low 60’s to high 70’s depending on the bike

    High-speed compression – How the suspension moves through the travel from High-speed hits, not high-speed riding. For example, rocks, roots, braking bumps, landing from jumps/drops etc.

    Low-speed compression – How the suspension moves through the travel from low-speed movement, not low-speed riding. For example, when under compression through a berm, going up a transition of a jump etc.

    Preload – How much the coil spring is compressed in its static state.

    Bolt On – An axle that is incorporated into the hub with nuts on the end. Designed to work with traditional 9mm or 10mm dropouts.

    Rebound – How fast a shock returns to full extension.

    Sag – How much travel is used under rider weight.

    Shock pump – A high-pressure air pump used to adjust air shocks, running at a much higher pressure than a normal inner tube/tyre pump.

    Spring rate – The force needed to compress the shock.

    Triple clamp – A fork with two crowns, used on long travel DH forks to combat flex.
