S C OT T CARBON EXPERTS C ARBON FIBER Carbon composites are the most diffused materials in the high performances bike industry . The technological development of this material has made great strides in past years and today we can build reliable frames with high performance and at an extremely light weight . The benchmark fixed today thanks to this composite is something that goes beyond any previous expectations- this is why carbon composite can be considered the ‘black gold’ of our industry .

HMX-SL utilizes Nano-technology, which incorporates a carbon nanotube reinforced epoxy resin as well as MR70 carbon fiber . The carbon nanotubes offer improved strength perpendicular to and off-axis with regards to fiber direction, allowing for better inter-laminar shear strength . The cohesion between the fibers is improved compared to our industry leading HMX carbon blend offering unprecedented resistance . Strategic use of this new material results in a frame that is lightweight without compromise in power transfer .
SCOTT has improved upon the now conventional high modulus carbon fiber, HMF, used throughout the bicycle industry . HMX is a fiber blend used by SCOTT, and is 20 percent stiffer than its HMF counterpart for the same weight . This unique material allows SCOTT engineers to create incredibly light bikes with excellent riding characteristics . The cost of HMX, however, is three times that of HMF, and is therefore reserved for our high end frames .
HMF carbon fiber is used to maximize strength and to keep weight low . This material has an optimal blend of stiffness and strength that offers the best riding session . SCOTT’s engineering know-how is utilized in order to create the perfect lay-up with regards to orientation and fiber size . HMF fiber offers superior strength compared to the industry standard .
MF Carbon shares some of the raw materials used in HMF . However the layup is simplified by using fewer, thicker layers . This reduces the amount of preparation and preforming necessary, resulting in an even better value frame, at a slightly increased weight, with no sacrifice on quality .

EvoLap-TECHNOLOGY The choice of the most advanced carbon fibers in the market comes along with intensive use of specific tools for the analysis of carbon lay-ups, for example FEA (finite element analysis) software . This allows us to create complete virtual prototypes of complex products which incorporate all the physical phenomena that exist in real-world environments .
L AYER
With our proprietary EvoLap-Technology, we can simulate different forces on a virtual model of the frame and adjust the frame construction accordingly . Testing our frames in this virtual environment allows us to experiment with an enormous amount of different fiber orientations that would be impossible to simulate though prototyping .
