X-LAB GT8

Adventure-Ready Gravel Bike Built for Control, Comfort, and Conquest.

Welcome to Espresso Bicycle Repairs. If you’re the kind of rider who sees every road as an invitation and every dead-end as a new trail, the X-LAB GT8 is your ultimate companion. As X-LAB's first gravel platform, the GT8 is designed for stability, control, and long-distance comfort, transitioning effortlessly from smooth pavement to rugged dirt and from city streets to open trails. Wherever the road disappears, the GT8 keeps going.

The Espresso Bicycle Repairs Take

We're huge fans of versatile bikes here at Espresso Bicycle Repairs, and the GT8 hits the mark flawlessly. It's built for those rides that refuse to follow a route—mastering uneven terrain, unknown turns, and epic mixed-surface days where stability, speed, and confidence are paramount. We particularly love the unique seat stay design, which perfectly balances strength, compliance, and precision handling to keep you comfortable on all-day adventures without sacrificing race-ready stiffness.
