Smooth Titanium Performance

Why We Love It
Just a few miles down the road from The Pro's Closet, a handful of skilled framebuilders are creating works of art at Mosaic Cycles. For the most discerning roadie titanium fans, the RT-1 Disc is the ultimate performance powerhouse. Oversized, double butted, thin-walled straight gauge frame tubes provide world-class handling, top-shelf power transfer and featherlight frame weight. For a crisp aesthetic and cleaner cables, Mosaic has them routed internally through the frame. To make you feel confident when cornering and stopping, this version of the RT-1 D is specced with disc brakes. Bonus, disc brakes also allow more clearance for up to 38mm tires and when combined with the buttery smooth ride of titanium, provides compliance thats hard to match.
