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.

Seatstays - They are quite simply the most amazing seatstays on any bike – seatstays end up carrying very small loads, an effect that is even more dramatic in combination with the new Squoval chainstays. The seatstays in an R3 are almost unnecessary for the vertical loads, they only provide torsional stiffness. Therefore, the R3 seatstays to act as leaf springs in the vertical plane while having a more standard dimension in the lateral plane for torsional rigidity. Thus it combines strength, comfort, torsional stiffness and minimal weight.
