What bikes say only composite? Carbon fibers frames are Advanced composites. as stated before they are weaves, prepreg and wetted making an extremely strong and light material that is not dependent on tube radius to increase tensil and torsional strengh. Early composite bikes were made of carbon and the method of forming tubes was thermoplastics. these were not stable and reacted to reheating, being left in a hot car , etc. most bikes today are newer advanced composite CF, aluminum, titanium or steel, oh yeah don't forget bamboo. comparing the old composites, that are obsolete, to the new advanced stuff is just sales mumbo jumbo, apples to oranges if you will.
