I don't know. Does it? Personally I like to see a bicycle frame crafted out of bamboo and oak. Okay, I know it's been done already. Lemond is building a bamboo/oak bicycle for 2007. It showed at interBike this year. The pine cone lug work is beautiful. And, it's stiff. Lemond is also putting out a ceramic frame set with carbon lugs and pine cone drop outs. The fork blades are bamboo with turtle shell fork ends. Beautiful frame set but hard to mass produce.
Ritchey is on the cutting edge. He's producing a frame set made from corn -- that's maze if you're a native America -- and recycled automobile tires. The lugs are pine cones (see a pattern here?) and the drop outs are petrified wood. The fork blades are made from rhino tusk -- very unusual choice of material but Ritchey says the rhino tusk is the stiffest and most shock absorb material on the market right now. It is expensive and cost prohibitive to make an entire frame set from rhino tusk, Ritchey said in a recent interview with Bicycle Retailer.
Probably the most forward thinking design in terms of materials is coming out of the Japan. Fuji is building a limited number of framesets using lava rock found on and around Mt. Fuji. This porous rock is light an stiff but not easy to work with. The frame come replete with rhino tusk lugs AND drop outs. The head tube is bamboo incrusted with turtle shell inlay. The crowning jewel though is -- get this -- a bb shell made of limestone, which is a very unusual choice. They say it's a bit heavy, but it's very stiff and easy to work with. The fork blades are whale bone and the fork ends are -- you guessed it -- rhino tusk.
I predict that, when scientists figure out how to successfully clone rhinos, you'll see entire frame sets and even some high-end groups using rhino tusk as it's primary material.
