let s review say it with me titanium is the finest high-performance bike frame material in the world so how do we improve on the best shape it baby we are constantly testing and refining the art and engineering of high-performance frame building a few years ago we pioneered the use of geometrically enhanced tubing g.e.t technology to improve the basic performance of our tubing never content to simply go with the flow we kept the research lights burning and developed new methods of shaping the tubes to get the maximum performance out of each one a bike frame constantly undergoes some rather extreme twisting forces even when you are just climbing a hill by shaping the tubing in different directions we are able to counter and offset the frame stresses during even aping the most extreme riding conditions by constantly evaluating the stress loads imposed on a bike frame during mposed the most extreme cycling situations our engineer/geeks have arrived at shapes that counter these stresses and as a bonus this shaping means we don t need as much material to do the job ­ hence weight savings our new proprietary forming technology allows for weight savings and performance characteristics on a scale that has never before been possible flattened oval p.f.t this particular tube is used as the seat tube on the ghisallo vortex and ultimate with the super broad base this shape delivers incredible increase in lateral stiffness to the bottom bracket junction teardrop g.e.t the performance characteristics of this tube shape makes it ideally suited to the seatstays besides the obvious aero properties a gracefull sweep along the length of the tube adds supple vertical compliance for a smoother ride flared diamond p.f.t the strong ridges increase torsional resistance and longitudinal flex resistance the flared end increases latitudinal flex resistance primarily where it intersects either the head tube or seat tube bladed g.e.t bet you can guess what the main advantage to this shape is that s right aerodynamics its narrow profile presents less frontal surface to the wind and thereby reduces drag as a downtube it also provides incredible vertical stiffness flattened diamond g.e.t the application of this tube shape with its wider profile actually serves to increase the force resistance of the tube it is attached to we also morph the direction of the greater dimension from horizontal to vertical where the needs are different at the other end of the tube shape technology nology 6 litespeed.com no other tube in the world can give you the same performance characteristics it is truly revolutionary enhanced diamond p.f.t as the top tube this shape provides greater torsional resistance than conventional round tubes with distinct peaks at the compass points it gives both lateral and vertical stiffness increases over round tubes orbital g.e.t although this shape only slightly is differs from a conventional round onal tube it increases the stiffness ffness along the long axis meaning we can use less material less weight and maintain conventional structural integrity capsule g.e.t the shaping technology used in the chainstays could take up an entire physics lesson in itself our research has shown that the structural dynamics of the chain itself plays into unequal lateral forces being applied during a pedal cycle therefore we can maximize applied force by assymetricall assymetrically profiling the chainstays 7 litespeed.com chris newton winning the 2005 colne grand prix recycling.co.uk/litespeed İhenry iddon
