The Mosaic GT-1 45 is designed around a 42-45mm tire, a gravel chainline, and optional SRAM UDH dropout, meaning you’ll likely find yourself riding routes a little off the beaten path, and trust us, that’s where the most fun is to be had. Custom geometry is drawn up based on bike fit information provided by you and your Mosaic dealer, making every GT-1 unique and made-to-order for the intended rider.

The Mosaic double-butted tubeset makes for a lightweight and exceptionally strong frameset that can be tuned and built to address your specific needs. Larger diameter internally butted tubes are both lightweight and incredibly strong, characteristics that define what a gravel bike should be. Some smaller, perhaps less visible details included on the GT-1 include internal Di2 routing, and tube-in-tube internal brake routing that sits completely flush at it's entry and exit point, eliminating any cable rattle.
