Road :: Ti-Carbon

Precise and burly. Light and strong. Modern and timeless. Beautiful and functional. Fast and comfortable. Subtle and stunning. Technology usually reserved for the companies with million dollar R&D budgets, used by a company of three.

“The most bad ass.” That’s what we wrote at the top of the 3′ post-it we used to plan our first bikes before anyone knew we existed. This is what we meant. This is the pinnacle.
