Mosaic GT-2 45
​
The 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 our team of exceptionally skilled craftspeople here 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!

Mosaic Cycles GT-2 45 Shimano GRX.

An ENVE Gravel Fork and Cane Creek headset come as standard on every GT-2.

Every Mosaic frame is handmade by us in Boulder, CO every step of the way.
