X-Lab AD9 Shimano Dura-Ace + Branta C50 ULR Road Bike

The AD9 represents the pinnacle of X-LAB engineering. Designed in the wind tunnel and proven at the highest level of professional cycling, it is the official race machine of the XDS Astana WorldTour Team.

Every tube profile, surface transition, and structural element has been refined to minimize drag and maximize speed.

When the road opens up and the pace rises, the AD9 delivers what matters most: pure aerodynamic advantage, tested to the fullest by CFD and by wind tunnel.

This is the fastest road bike in the X-LAB lineup.
