Principia Ellipse SX
Tapered seat and down tubes, along with Ellipse Project fork, head tube, bottom bracket and dropout propel the Ellipse ahead of the pack in STW (stiffness to weight) testing. The SX Differential Slope variant progresses from a standard 6 cm slope, to a moderate 3 cm slope on larger sizes.

• Tube Insert Welding - Unglamorous and invisible, but definitely important. The tubes are fitted inside each other rather than on top of each other, i.e. the seat tube is inserted into the bottom bracket and the top tube into the head tube. It allows for closer tolerances, better weld quality and saves excess material. This all adds up to a lighter frame, without any sacrifice on the parts of safety or performance.

• SX Geometry - SX Differential Slope Geometry varies the amount of slope according to frame size. The smaller frames get a more dramatic slope, while the larger frames feature only a moderate slope. In a sense, the work on the SX slope technology began 4 years ago, when Principia introduced the S6 (6 centimetre slope) technology. What we found was that while the S6 slope was perfect for the smaller sizes, it often produced an un-aesthetic and structurally unsound seatpost length, on the larger frame sizes. The SX technology is a new, individual approach to sloping frame geometries, ensuring a proper fit for all frame sizes.

F600 Hi-Quality Carbon/Alloy Road forks

Vitus Bikes have a long heritage in road cycling and have racked up quite a few Pro Tour stage wins over the years with riding greats such as Irish road cycling star Sean Kelly who claimed stage victories in the Tour de France onboard a Vitus bike. Vitus pioneered the bonding process that is now widely used in the manufacture of carbon frames and this process has been developed and refined and is still utilized in all high end Vitus Carbon Fibre Forks including the F600. Utilizing sound design concepts through to the use of high grade aerospace alloy and carbon fibre you can be sure that each and every Vitus product has been designed to provide the perfect balance between performance, function and style.
