Mosaic GT-2 45

The Mosaic GT-2 is now available in two different frameset options and just like every Mosaic, the GT-2 is handmade in Boulder, CO.

 

The GT-2 45 will deliver the riding experience you expect from a Mosaic, at a price point that makes a titanium gravel bike from Mosaic more accessible than ever before.

 

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! Meanwhile, the GT-2 AR is a quick and versatile all-road bike, designed around a maximum tire size of 40mm and it's equally at home on the pavement as it is on the dirt.
