  1. Specialized FACT “Functional Advanced Carbon Technology”

  2. Molecular Carbon Structure • The “Bucky Ball” • 60 Carbon molecules arranged in the structure of a ball, similar to a Soccer ball. Also known as C60. • Nanotubes • The advantage of carbon arises from the empty space, where metals have very little dead space and are therefore much more dense.

  3. What Is Carbon Fiber? • Graphite Fiber Reinforced Polymer • Carbon + Resin • Higher quality “Carbon Fiber” involves improving not only the stiffness of each individual fiber, but also the quality of resin. • Without one of the two elements, either one becomes useless in it’s application, imagine rebar and concrete used in a bridge. • Structure comes from Unidirectional fiber, whereas 1K, 3K, and 12K weaves provide additional protection without structural significance. • Modulus = Individual fiber stiffness; increasing modulus involves baking each fiber at higher temperatures which rapidly increases production costs. • Higher modulus fibers are essentially refined at a higher temperature which increases the bond strength between each carbon molecule. • Higher modulus allows the use of less material to achieve equal stiffness and strength when compared to the use of less modulus fibers.

  4. Construction Methods • Triple Monocoque: Frame is produced in 3 stages • Head tube, down tube and bottom bracket shell, top tube, seat tube • Seat stays • Chain stays

  5. Az1 and FACT IS • Az 1, pronounced “As one” • Utilizes tube to tube construction • Mitered joints are glued, wrapped and baked. • FACT IS • Monocoque top tube, head tube and downtube • Monocoque seat tube, bottom bracket shell and downtube extension • Az1 joints at downtube, top tube/seat tube, seat tube/seat stays and bottom bracket/chain stays. • Combination of construction methods for the lightest, stiffest and most compliant frame possible.

  6. Road Technology • Primarily “E” or Elasticity index fibers • R11: Pitch or E630, only used in Tarmac SL2, we are the first company to utilize this grade of carbon in bicycle frames. • R10: E390 • R8: E285 • R6: E240

  7. Carbon Crank • Carbon Crank provides the highest stiffness to weight ratio of any crank in the industry.

  8. Mountain Technology • “Y” or Yield Fibers, which provide higher impact resistance than “E” fibers • All mountain bicycles utilize Y579, with mixing of “E” fibers • Much higher crush and impact resistance than the composites used in our road line.

  9. Advantages • Very engineering friendly • Greatest potential for technological advancement • Highest strength/stiffness to weight ratio of any material currently used in the cycling industry.
