X-LAB AD8

Inspired by the WorldTour-proven AD9, the AD8 brings elite aerodynamic performance to a wider range of riders.

Built with the same racing philosophy but tuned for broader accessibility, the AD8 delivers responsive handling, high-speed efficiency, and the unmistakable feel of a true race platform.

It’s the essence of X-LAB speed—engineered for the real world.

Real Speed, Real Roads

The AD8 is built for riders who measure their rides in efforts, not excuses. It unleashes race-bred aerodynamics that you can feel on everyday roads, from solo tempo days to fast group rides.

WorldTour DNA, Made Attainable

It’s the same exact frame design and geometry as the AD9, because speed doesn’t need reinvention. The AD8 brings the platform raced at the highest levels into a build meant for serious riders chasing their next upgrade.

T800 Carbon, Dialed for Performance

Engineered with Toray T800 carbon to hit the sweet spot: lightweight, stiff, and responsive, delivering that desirable aero advantage without the halo-bike price tag.
