Mosaic
GT i55 32
Gravel Race · 32-Inch Wheel Platform
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 i55 32 is a handmade titanium gravel bike designed from the ground up around 32-inch wheels, debuting at the MADE bike show in Portland, OR.
Rather than adapting an existing frame, we treated the GT i55 32 as an entirely new platform: geometry, rear triangle, axle standards, tire clearance, and an in-house 32-inch gravel fork, all developed together to make a big wheel feel small.
— 55mm (2.2") tire clearance, purpose-built around 32-inch gravel tires
— Mosaic Zero Components 32-inch Gravel Fork — 445mm axle-to-crown, 60mm offset
— Compact 440–445mm chainstays, offset seat tube, 3D-printed titanium yoke
