“Functional Advanced Carbon
Technology”
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.
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.
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
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.
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
Carbon Crank
• Carbon Crank provides the highest
stiffness to weight ratio of any crank in the
industry.
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.
Advantages
• Very engineering friendly
• Greatest potential for technological
advancement
• Highest strength/stiffness to weight ratio of
any material currently used in the cycling
industry.
