She Blinded Me With Science!

Thomas Dolby. If you know that name, it's time face the facts. You are old.

"Conceptually, single-wall carbon nanotubes (SWCNTs) can be considered to be formed by the rolling of a single layer of graphite (called a graphene layer) into a seamless cylinder. A multiwall carbon nanotube (MWCNT) can similarly be considered to be a coaxial assembly of cylinders of SWCNTs, like a Russian doll, one within another; the separation between tubes is about equal to that between the layers in natural graphite. Hence, nanotubes are one-dimensional objects with a well-defined direction along the nanotube axis that is analogous to the in-plane directions of graphite."
—M. S. Dresselhaus, Department of Physics and the Department of Electrical Engineering and Computer Science, Massachusetts Institute of Technology

Carbon nanotubes possess many unique properties which make them ideal for bike frames. Nanotubes elastically buckle rather than break when deformed, which results in very tough framesets for bicycles.
CNT has amazing toughness: the Young's modulus is over 1 Tera Pascal. (That means it's as stiff as a diamond.) The estimated tensile strength is 200 Giga Pascal (that means it's tougher than that kid that took your lunch money in 5th grade.). These properties are ideal for reinforced composites, like the amazing BMC ROAD BIKE LINE!

BMC uses Easton's CNT tubesets for their high-end carbon bikes. That's the very same CNT used in deep-space probes!

Bucky Ball:

"It is the roundest and most symmetrical large molecule known to man. Buckministerfullerine continues to astonish with one amazing property after another. Named after American architect R. Buckminister Fuller who designed a geodesic dome with the same fundamental symmetry, C60 is the third major form of pure carbon; graphite and diamond are the other two." Bucky Balls - Andy Gion.

Bucky balls are also known as C60 molecules & buckminsterfullerene. It is a series of molecules made up of 60 carbon atoms arranged in a series of interlocking hexagons and pentagons, forming a structure that looks similar to a soccer ball. C60 is actually a "truncated icosahedron" (please tell me you stayed awake in geometry), consisting of 12 pentagons and 20 hexagons. It was discovered in 1985 by Professor Sir Harry Kroto, and two Rice University professors, chemists Dr. Richard E. Smalley and Dr. Robert F. Curl Jr., [for which they were jointly awarded the 1996 Nobel Lauriate for chemistry] and is the only molecule composed of a single element to form a hollow spheroid. MMMMM...hollow spheroids...I'm getting hungry.

I bet ya TEN BUCKS that 'Vader's helmet was made of Carbon Nano Tubes and bucky-balls!

The buckyball, being the most round of all molecules, is also quite resistant to high speed collisions. The buckyball can actually withstand hitting a steel plate at 15,000 mph, bouncing back completely unharmed! When squashed to 70 percent of its original size, the buckyball becomes more than twice as hard as a diamond. THAT WOULD MAKE A SWEET HELMET! Imagine a helmet that could deal out more damage than it took! The bucky ball and diamonds being so closely related makes me wonder if my fiancee would rather have a bucky-ball ring than that colorless chip of Yugo windshield safety glass she's wearing now...
