Description
NOTE: Sizes Small and Large will arrive on September 26th.
Turn every road—and every road that disappears—into your next adventure with the X-LAB GT8. Designed for gravel racing, long mixed-surface rides and weekend bikepacking, this lightweight carbon gravel bike combines confident handling with the comfort and control needed to explore beyond the pavement.
The Toray T-800 carbon frame provides a responsive yet composed ride, while clearance for tires up to 55c gives you the freedom to add more traction and cushioning for rough terrain. Shimano GRX Di2 electronic shifting delivers fast, precise gear changes, and the wide-range 1x12 drivetrain helps you tackle steep climbs and changing conditions without complicating your setup.
The GT8 also includes features rarely found at this price, including a Branta integrated power meter, Apple Find My anti-theft technology and an integrated downtube storage compartment. Carbon wheels, a carbon cockpit and multiple accessory mounts complete this exceptionally capable gravel bike.
