32 Inches. Zero Apologies

32-inch wheels aren't new - but until now, the bikes built around them have largely felt like experiments. Mosaic is changing that. The GT-2 i55 32 is a handmade titanium gavel bike design fro the ground up around 32-inch wheels.

Rather than adapting an existing frame, we treated the GT-2 i55 32 as an entirely new platform: geometry, rear triangle, axle standards, tire clearance and an in house Zero Components 32-inch carbon gravel fork all developed together to make a big wheel feel small and a bike that brings all the performance benefits of the larger wheel size.

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.

Currently the GT-1 i55 32 is only available as a Made to Order frame, Batch Built coming soon…
