Multi-shape toptube - The toptube loading is a lot more complex, hence it is Squoval near the headtube and seattube and oval in the center.

Oversized bottom bracket area – The increased volume of the bottom bracket area provides great STW. The smooth contours of the BB volume help both for this BB stiffness and also for its strength as the fibers have a much more continuous path to transfer the loads better.

Lay-up optimization - The stiffening plies are added to the sides of the tubes where they have the greatest effect in bending. They are feathered to distribute the loads into the structure. More plies are added on the bottom of the down tube, the headtube and the toptube to distribute the loads from a potential headtube impact. Finally, Kevlar is added to that same area and downtube to prevent catastrophic failure.

RS Seatstays - Based on the revolutionary R3 seatstay design, the RS seatstays offer even more vertical compliance thanks to their built-in deflection mode.

Longer headtube length – Same handling philosophy as our other road bikes, but with longer headtube for those who prefer a higher handlebar position.

Special XS size – The new XS size completely eliminates toe-overlap (see geometry section for more information).
