X-Lab AD8

"The best bike I've tested under $5000" - Bicycling Magazine
Same wind-tunnel tested aero design as AD9
Lightweight yet durable Branta wheelset
"Feels like the one riders will circle first" - BikeRumor

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.
