The X-LAB GT8 is a carbon gravel platform designed for stability, control, and long-distance comfort across pavement, dirt roads, rough trails, and mixed-surface routes. With generous tire clearance, in-frame storage, multiple accessory mounts, electronic shifting, carbon wheels, and an integrated power meter, the GT8 arrives equipped for gravel racing, adventure riding, and short bikepacking trips.
