I stopped by the Calfee booth drawn by the alluring sight of what looked from a distance like burled wood lugs on a bamboo 29" mountain bike. How did they do this I asked? No secret but hard work. Hemp fibers were run through resin, wrapped around the joint then polished, polished, polished until the tube connection looked like a piece of fine furniture. Few people can afford this sort of thing, but it's fantastic to look at and may induce larger companies to inject a bit of craftsmanship into their mass produced products like the Bianchi Dolomiti (bringing chromed lugs back in a factory built bike).
