EXPERIENCE: COMPETITIVE ROAD
Like You, Only Better.
When a road bike is right, it's little more than an extension of your body,
an appendage that moves you across the landscape with shocking ease. And
it's lean, efficient and sharp, like your corpus durus. (Right?) Our Tarmac
is like your body in all those ways and many more, but unlike your body it
weighs a little over a kilogram and has a lifetime warranty.
Learn (more than) a little about the design, materials, fabrication, and competitive analysis of composite bicycle frames. Read Taking The Witchcraft Out Of Advanced Composite Bicycle Frames. (Adobe PDF, 750K)
