GT-45: Go Bigger. Ride Harder. Demand the best.

The GT-2 45 can go tire-to-tire up against any high performance gravel bike available today. Designed to comfortably fit a measured 700x45c tire and confidently handle any gravel riding scenario imaginable, the GT-2 is made of a size-specific mix of straight gauge, thin wall 3AL/2.5v titanium tubing resulting in a tuned ride quality balancing responsiveness and compliance specifically for the unique rigors of gravel. Ride it everywhere, race it anywhere, and like most Mosaic owners, ride it forever.

All GT-2’s are precision batch-built by the same team of craftspeople working on our top-end GT-1 Series bikes and feature the same exquisite finish quality and are available in 9 sizes. This is the jam for riders looking to save more dollars than grams and don’t mind skipping some of the custom options.

Geometry

Rider Specific Geometry

With a fit-first design approach, custom geometry is drawn up based on bike fit information provided by you and your Mosaic Dealer. Taking into account each rider’s aspirations and use case for the bike, we continue to fine-tune the design to culminate in a riding experience and handling that is perfect for each unique frame that we build. Custom geometry is included as standard on our 1-Level bikes, giving us the opportunity to build the perfect bike for each rider 100% of the time.
