The titanium RT-1 from Mosaic Cycles is the US brand’s flagship road racer. Handbuilt in Boulder, Colorado, the RT-1 benefits from custom-butted 3/2.5 titanium tubes, an oversized 44mm headtube, rock-solid chainstays, and an ENVE road carbon fibre fork. Combined, it’s a cocktail built for comfort, stiffness and speed. 

Our stock geometry build brings together some of our all-time favorite components and finishing details, including Campagnolo’s Super Record groupset (in a mechanical rim brake edition), BORA WTO 33 wheels and DEDA finishing kit.

The bike’s paint scheme blends a deep blue base with white Mosaic graphics and bare titanium areas across the chainstays, lower down tube, seat tube and hub.
