Performance in Every Detail
A closer look at the engineering, titanium construction, and all-terrain capability that define the Mosaic GT-1 i55.
55mm Tire Clearance
The completely redesigned rear triangle provides clearance for massive 700 × 55mm tires—the most tire clearance of any Mosaic model. A 3D-printed chainstay yoke, offset seat tube, and 430mm chainstays allow Mosaic to accommodate that volume while retaining responsive, race-oriented handling. The result is greater traction, comfort, and control when the terrain gets rough without turning the GT-1 i55 into a sluggish adventure bike.
Double-Butted Titanium
At the heart of the GT-1 i55 is Mosaic's 3A/2.5V double-butted titanium tubeset. The frame is engineered to balance stiffness where power transfer matters with the compliant, lively ride quality that makes titanium exceptional over rough terrain. It's a modern gravel race chassis built around a material renowned for durability and long-term ride quality.
Handlebars
The GT-1 i55 features a fully integrated cockpit with ENVE In-Route components and completely hidden brake routing. The IS52/IS52 headtube and Mosaic's proprietary carbon gravel fork create a remarkably clean front end while maintaining the control, stiffness, and precision required for aggressive gravel riding.
