Mosaic takes the emerging 32-inch wheel format beyond experimentation with a ground-up titanium platform designed for speed. 32-inch wheels aren’t new, the industry saw the invasion of 32-inch technology hit at Sea Otter this spring. However, until now, the bikes built around the new platform have largely felt like experiments. Mosaic is ready to change that. Introducing the Mosaic GT i55 32, a handmade titanium gravel bike designed from the ground up around 32-inch wheels. It’s built with the singular goal of taking the theoretical performance advantage of a larger wheel and turning it into a gravel bike you actually want to ride.

One person is dead and another is hospitalized after a crash on the Stevenson Expressway on Chicago's Southwest Side early Saturday morning, Illinois State Police said.

Mosaic GT i55 titanium gravel race bikes get bigger 55mm tire clearance and in-house designed carbon fork, while preserving a race-ready ride!

Ground-up redesign delivers Mosaic’s most capable gravel platform yet with 55mm tire clearance, in-house designed fork, and modern integration. Gravel riding has changed. Courses have become rougher (and muddier), riders are venturing farther from pavement, and wider tires have become an essential tool for riders seeking more speed, comfort, and confidence over unpredictable terrain. The new Mosaic GT-1 i55 and GT-2 i55 were built for exactly this evolution. Representing a complete redesign of the company’s gravel platform, the GT-1 i55 and GT-2 i55 become the most capable gravel bikes Mosaic has ever produced.
