Mosaic’s RT-1 represents the pinnacle of titanium road bike construction. It’s handcrafted right here in Boulder, CO, and sports a blend of oversized internally double-butted and thin walled straight gauge 3/2.5 tubes. This combination makes the bike stiff, responsive, and lightweight, all without losing the sublime ride quality titanium frames are known for. This means that while the RT-1 is a machine that’s built for speed, responding instantly when you put the power down, it’s still compliant enough to keep you feeling fresh on those long all-day rides. Its titanium construction also means that the frame will maintain these enviable characteristics throughout its lifetime; resisting corrosion, fatigue, and damage with little maintenance. The frameset is finished off with ENVE’s carbon road fork, itself a fine work of art. Like the frame it resides in, it is stiff and precise, while providing ample damping for vibration and road noise. The RT-1 is a race bred machine, ideal for the discerning competitor who is interested in something that will both perform and last, and do it all beautifully.
