    Wheels & Tires




    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.


    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.


    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.













    1. Superspeed 2 Eagle is a feature packed bike at a price point that most serious riders can afford.
    2. Featuring a 12 speed Eagle drivetrain, the Superspeed 2 Eagle 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 2 Eagle is equipped with a Rockshox Judy Silver Boost 100mm adjustable air suspension fork.

    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.


    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.


    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.


    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.


    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.


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


    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.


    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.


    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.


    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.

    Benefits of 1x drivetrains

    1. Better - lighter shifting. The chain line directly relates to the shifting quality and lifetime of components. This position can be optimized for 1x systems.
    2. Simplicity. Single shifter is easier to get used to. Less thinking and more pedaling.
    3. Ease of Installation. 1x systems only have one cable, and less components, making installation easier and quicker.
    4. Weight. Shorter chain, single chainringa nd no front derailleur means that a 1x drivetrain can be significantly lighter than a 2x or 3x drivetrain. Lighter overall weight of the bicycle.
    5. Cleaning. Without a FD, the chain can be moved well away from the crank. This makes it easier to clean and less likely to build up mud.
    6. Chain retention. The clutch mechanism effectively lessens chain bounce over rough terrain. We use clutch rear derailleurs on all our adult 1x bikes.
    7. Chain retention. Narrow Wide chainring keeps chain in line and negates the need for a front chain device.
    8. Easier climbing. Major climbing advantages over 2x and 3x drivetrains.
    9. Aesthetics and Function. Bike design can more closely follow function, and intended design language without the additional complications and requirements that multi-chainring setups and front derailleurs present. This means better looking, better working bikes.
    10. Improved ground clearance. More ground clearance with a single chainring.
    11. Cleaner cockpit. With less shifters on the bar, the cockpit is cleaner and there are less cables to worry about.
    12. Maintenance. 1x systems are easier to maintain than 2x or 3x systems and parts are easier to find
    13. Wear and Maintenance. Availability of parts and spares - older systems are becoming more difficult to work on due to this. Yes, 1x is much simpler and easier to find parts for as well as easier and cheaper to maintain. Also less components to wear against, compared to FD changing gears.
    14. Frame design. Suspension platforms can be dialled in and perfectly tuned to a specific single chainring.
    15. Frame Design. No FD - means this area can be utilized for other elements or design features such as suspension pivots & geometry can be purpusefully optimized.
    16. Less chainrings = More space = More/bigger tyre clearance.
    17. Less noise ultimately means a more enjoyable ride.
    18. With less chainslap, the paint on your frame stays neater for longer.
    19. Component designers and manufacturers spend R&D money on the newest and most prominent tech - and so with 1x leading the charge - 2x and 3x systems are not getting any attention from an R&D perspective anymore, meaning that the tech is quickly becoming outdated compared to the newest 1x systems


    Answering the most often asked 1x questions.

    1. Can I change my double/triple chainring to a single chainring setup?

      This should be possible on most bicycles, provided the crank spider has a suitable single speed chainring option. Ensure that the single chainring is an apropriate size for your riding and that it has suffcient frame clearance.
    2. Do I need a chain guide to run a single chainring?

      It depends on the terrain you plan on riding. Rougher terrain could benefit from running a chain guide. Narrow-wide chainrings and derailleur clutches have made it possible to run single chainring setups without a chain guide.
    3. What advantages are there to a single chainring setup?

      There is no possibility to cross-chain your drivetrain. Reduced movement of the chain increases the lifespan. Simplicity means reduction in components, weight and ease in cleaning.
    4. What do I need to know to change to a single chainring setup?

      Start by selecting an appropriate chainring size, that is compatible with your frame and crank. Consider your cassette size, and how the particular single chainring will influence your gear range.
    5. Do I need a new crankset for a single chainring setup?

      Possibly, double and especially triple chainring cranks have variable chain lines. Simply installing a single chainring on such a crank, can result in issues with shifting and chain retention.
    6. What is a narrow-wide chainring?

      Narrow-wide chainrings have alternating narrow and wide teeth profiles, this reduces chain bend and makes it less likely for the chain to drop from the chainring. Not all narrow-wide profiles are the same, and some have greater chain retention abilities while others may be quieter, however, all will remarkable reduce chain drops over uneven terrain.
    7. What is a derailleur clutch?

      Derailleur clutches aim to reduce chainslap and the resulting chain drop by holding the jockey wheel cage steady over rough terrain. Most derailleur clutches use a mechanism to increase the friction required to move the jockey cage.
    8. How do I turn my derailleur clutch on?

      Most derailleurs with clutches have an on/off switch somewhere on the derailleur - ensure that the clutch is "on". An exception to this is SRAM derailleurs which have an always on clutch.
    9. Why would I turn the derailleur clutch off?

      This should be possible on most bicycles, provided the crank spider has a suitable single speed chainring option. Ensure that the single chainring is an apropriate size for your riding and that it has suffcient frame clearance.
    10. Why do my gears change when I backpedal?

      This is not unusual or a problem on a 1x drivetrain.
    11. When I turn the clutch on my gears are harder to shift, or not set correctly, why?

      Having the clutch on may increase the lever force as you need to overcome increased friction in the derailleur cage (particularly when shifting into an easier gear), this is normal and part of the trade off of reduced chainslap and drops. It is important that the gears are set with the derailleur clutch "on", otherwise they may not shift correctly when it is switched on.
    12. Often, my chain drops at the same place. What is wrong?

      “There is likely a burr or deformation somewhere on the teeth of the drivetrain. Inspect your components thoroughly to see any obvious signs of damage on the drivetrain. Replacing the defective component, should resolve the chain dropping. If not resolved, your LBS (Local Bike Shop) should be able to assist you with the matter. "
    13. My chain drops, even when I am on smooth terrain. What is wrong?

      The cause can likely be from a stiff link in your chain. Set the chain in a straight chain line, and back pedal. A stiff link will make a 'click' sound when passing through the rear derailleur wheels. Lubricate and flex the chain to loosen the stiff link.
    14. There is a 'ticking' sound on my bike, what can I do?

      There are a number of reasons for strange sound on your bicycle. Your LBS are best geared to try and resolve audio anomolies on your bicycle.
