The X-LAB AD8 Ultegra Di2 (2026) brings race-focused performance to a platform built for real-world riding. Inspired by the WorldTour-proven AD9, it carries the same racing DNA with a more accessible setup for riders who want speed, efficiency, and confident handling.
Designed with aerodynamics at its core, the AD8 delivers responsive acceleration and stability at speed while maintaining the versatility needed for training, fast group rides, and race day. The Shimano Ultegra Di2 drivetrain provides fast, precise electronic shifting, complementing the bike’s performance-driven character.
Finished in the striking Sunspot Red/Black colourway, the AD8 combines WorldTour-inspired engineering with a bold, modern finish.
