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.
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.
