The Mosaic GT-2 45 will delivers the riding experience you expect from a Mosaic, at a price point that rivals the plentiful mass-produced options that are available. Like every Mosaic, the GT-2 45 is built by their team of exceptionally skilled craftspeople in Boulder, CO every step of the way from design, to framebuilding, welding and finishing.

The GT-2 45 is designed around 45mm tires, meaning you’ll likely find yourself riding routes you never thought possible on a “road bike”, and trust us, that’s where the most fun is to be had! Most times up to 48mm (measured) will clear in the frame and fork for those looking for even larger tire clearance. The GT-2 45 also works well with a second pair or wheels set up with a larger slick for road/smoother gravel riding for even more versatility and value.

Finish options include Standard Raw Finish (Satin/Blasted Base w/ lightly brushed logos) - Included as standard on 2-Level frames. Also available for an additional $500 is the Ghost Finish (Satin/Blasted Bare Ti Base w/ Dark Etched Bare Ti Logos) or the Shadow Finish (Brushed Bare Ti Base w/ Dark Etched Bare Ti Logos). Or the Factory Finish for $800 (Blasted Bare Ti Base, Brushed Chainstays, Brushed Bare Ti Logos with Etched Bare Ti Outline).

Complete bike build available with Sram, Shimano, and Campagnolo groups. Please call or email to discuss options.
