    GX EAGLE EQUIPPED RACE BIKE FOR THE XC ENTHUSIAST.

    The Superspeed is part of our flagship race-ready 29er carbon performance hardtail range. Our Monoburst technology has the seat stays joining the top tube without connecting to the seat tube, helping to stream the bump forces into the top tube and allow the seat tube to flex a little for added traction and comfort. This frame is stiff and efficient but also offers vertical compliance in the chainstays, top tube, seat tube, and down tube to maintain good comfort levels for a marathon and cross country racing. Short chainstays are possible with the single ring only setup and create an agile and nimble race machine, ready for any course that comes its way. Top carbon materials combined with a careful layup process ensure each frame is performance ready and super light. A super light integrated chainguard ensures the chainstays on during the roughest trails encountered.

    CUSTOM SEATSTAY

    The seatstays are connected directly to the top tube, isolating the seat tube from some of the trail feedback. Pedalling efficiency is not adversely affected by the frame’s flex. The seatstay profile is vertically compliant while retaining horizontal stiffness.

    CARBON HINGE

    The flattened off seat tube allows for fore/aft seat post flex, while the oversized downtube and chainstay junctions means the frame is stiff where structurally crucial. The carbon hinge works in conjunction with the detached seat stays, to provide comfort without compromising performance.

    WHY IT’S BEST.

    1. Superspeed GX is a feature packed bike at a price point that most serious riders can afford.
    2. Featuring a 12 speed Eagle drivetrain, the Superspeed GX has plenty of gear options to make climbing easier, and to maintain a decent top speed when the terrain allows. Eagle also has an even spread of gears over the range to keep cadence more natural when shifting up or down.
    3. Tyre clearance for higher volume XC tyres, up to 2.25"", means more setup options to suit your riding style, improved grip or to suit alternating weather or diverse terrain.
    4. MonoBURST technology uses material properties, along with tube shapes and profiles to create positive vertical flex in key areas for comfort and grip not normally available to hardtail racers. MonoBURST decouples the seatstays from the seattube, to redirect bump forces to the top tube.
    5. Superspeed 'Advanced Dynamics' geometry is race orientated, providing a well balanced, manoeuvrable platform as well as placing the rider in a comfortable position for all day racing.
    6. Superspeed GX is equipped with a Rockshox Recon Gold Boost 100mm adjustable air suspension fork.

    ENGINEERING NOTES.

    BOOST 148

    Wider hub spacing creates stronger wheel builds by widening the bracing angle of the spokes. Chainstay length is also reduced with the implementation of BOOST 148 for a nimble ride feel.

    CARBON HINGE

    The flattened off seattube allows for fore/aft seatpost flex, while the oversized downtube and chainstay junctions means the frame is stiff where it needs to be.

    CORRECT FLEXING

    Chainstays, top tube front/back and seat tube flattened areas help create vertical flex in the frame, similar to a parallelogram, to increase comfort while decreasing rider fatigue, as well as helping the bike keep contact with the ground over rough terrain. The rectangular tube shapes are wide and flat, enhancing lateral stiffness all round, while giving the frame vertical compliance.

    CUSTOM CARBON LAYUP

    The frame's carbon layup has been meticulously engineered to achieve the desired flex and stiffness characteristics that the Superspeed is designed for. Our Frame design uses tube shapes that flow into one another to limit excess carbon material layup by using fewer longer strips of carbon material instead of many smaller pieces overlayed around complicated shapes, which increases overall durability of the frame as well as keeping the frame light.

    CUSTOM SEATSTAYS

    Seatstays connect directly to the top tube, isolating the seattube from some of the trail bumps. Pedaling efficiency is not affecting adversely by the frame's flex.

    INTEGRATED CHAINGUIDE – 1X OPTIMISED

    We have an integrated superlight chainguide and 28-40 tooth chainring compatibility. There is no front derailleur mount on this frame.

    MONOBURST

    Seatstays connecting directly to the top tube allows for independent seattube movement. This is experienced by the rider as bump absorption - similar to suspension. Longer carbon sheets can be used in manufacturing, meaning less material and reduced weight.

    OPTIMIZED WEIGHT

    Frame strengthening and weight saving technologies have brought Superspeed frame weight down to an incredible 1000g (SBC Layup, Medium) and 1150g (Carbon Layup, Medium), making this our lightest mountain bike frame ever. Boost 148 hub spacing allows for a stiffer wheel build, and for the chainstay length to be reduced to 422mm. The short chainstays give the bike a lively and agile nature, unbeatable through technical terrain.

    RACE SIZING

    22mm has been added to the seattube on all size meaning that you can run shorter seatposts or a smaller sized frame while retaining low standover.

    SMART INTERNAL ROUTING

    Cable routing is fully internal - internal tubes make threading hosing a breeze. All that is needed is to insert the housing at the marked headtube port and it will be guided to the relevant cable exit.
