X-LAB AD8 Bike 2026Pure racing DNA, refined for the real world. The X-LAB AD8 delivers the aerodynamic performance and race-sharp handling of a World Tour-caliber bike, at a price point that makes it accessible to the riders who train like they mean it. Built around an XDS carbon frameset with Toray T800 fiber and shaped through CFD and wind tunnel testing for ultra-low drag, the AD8 pairs that performance chassis with a Shimano 105 Di2 groupset for precise, reliable electronic shifting. The Branta C45 UL carbon wheelset with carbon spokes at 1, 330g and a Branta carbon power meter crankset with integrated Apple Find My anti-theft technology round out a build that punches well above its weight.
