GENERAL INFO
xThe X-LAB AD8 Ultegra Di2 (2026) brings the racing DNA of the WorldTour-proven AD9 into a performance-focused platform designed for a wider range of riders.
Built around a wind-tunnel-tested aerodynamic frame and race-inspired geometry, the AD8 uses a Toray T800 carbon layup to deliver the stiffness, responsiveness, and high-speed efficiency expected from a true race bike. Whether accelerating out of corners, pushing the pace on the flats, or attacking a climb, the AD8 is engineered to turn every effort into speed.
This build pairs Shimano Ultegra Di2 electronic shifting with a Branta power meter crankset and Branta C45 UL wheels, creating a complete race-ready package weighing approximately 7.41 kg.
Finished in the distinctive Starlight Blue/White colourway, the AD8 delivers WorldTour-inspired engineering and performance in a bike built for racing, training, and fast everyday riding.
