Boost 12 x 148mm rear hub spacing with single ring boost chain-line. Allows for super short 422mm radial chainstay length and 2.3″ tyre clearance for extremely agile handling and good tyre clearance.
Seat stays join onto top tube to divert bump forces away from seat tube and therefore the rider. Seat tube is able to flex more for rider comfort and control.
Seat tube flares wider but narrower at BB to allow fore/after flex and comfort in the seat tube while remaining laterally stiff.
Chainstays, top tube front/back and seat tube flattened areas help create vertical flex in the frame, similar to 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.
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, and increase overall durability of the frame as well as keeping the frame light.
22MM added to seat tube length on each size [S/M/L] for added seat post support when near maximum extension. Allows smaller frame to be used better by taller riders too.
Internal cable routing for rear brake and rear derailleur use internal tubes to guide it from entrance to exit. Opening for seat post dropper cable at head tube to use internal dropper post. Frame and bike come with all adapters for DI2 or regular derailleur housing cable compatibility.
Rear break calliper joins chainstay to seat stay for optimal combination of strength and low weight in frame construction.
Integrated superlight chainguide and 28-40 tooth chainring compatibility. No front derailleur mount on this frame.
Seatpost is 27.2MM for comfort and light weight. Shimano press fit 92MM BB shell. FSA NO.42 ACB headset. Frame weight at around 1000G.
