Product Details

The XDS X-LAB GT8 is designed for riders who see every road as an invitation and refuse to let pavement dictate where adventure ends. As X-LAB's first gravel platform, this adventure-ready machine is built for the rides that don't follow a route, where stability, speed, and confidence all matter at once. Designed for control, comfort, and long-distance exploration, the GT8 transitions effortlessly from pavement to dirt, city streets to open trails, proving that it does not abandon performance when conditions change.

Constructed from advanced Toray T-800 carbon fiber with full carbon frame, fork, seatpost, and semi-integrated cockpit, the GT8 provides structural efficiency while accommodating the demands of varied terrain. The standout feature is its generous 55mm tire clearance, opening the door to bigger comfort, more grip, and expanded capability on the roughest surfaces. The unique seat stay design balances strength, compliance, and precision handling, maximizing ride performance while staying true to modern gravel standards with race-ready intent and UDH compatibility for the latest drivetrain technology.

The GT8 encourages exploration without limits through thoughtful integration of in-frame storage and accessory mounting points on both frame and fork, allowing riders to carry everything needed for extended adventures. Available in striking colorways like Afterburner Black and Slipstream Silver/Blue, the GT8 embodies both power and efficiency. Perfect for riders seeking a no-compromise gravel bike, it features Shimano GRX 717 Di2 electronic shifting for precise control in all conditions, a Branta C45 gravel carbon wheelset for lightweight durability, and a Branta alloy crankset with integrated power meter and Apple Find My tracking for added security.
