X-LAB AD8 105 Di2 Sunspot Red/Black
Description
Pure racing DNA, refined 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.
