X-LAB GT8 GRX715 Di2 Afterburner
Description
Adventure-ready gravel bike built for control, comfort, and conquest.
The GT8 is X-LAB’s first gravel platform, built for riders who see every road as an invitation.
Designed for stability, control, and long-distance comfort, the GT8 transitions effortlessly from pavement to dirt, city streets to open trails.
With confident handling and durable carbon construction, it’s a gravel bike that encourages exploration without limits.
Wherever the road disappears, the GT8 keeps going.
Where Gravel Gets Interesting
The GT8 is made for the rides that don’t follow a route. It was born to master uneven terrain, unknown turns, and long mixed-surface days where stability, speed, and confidence all matter at once.
Clearance That Changes the Ride
With up to 55mm tire clearance, the GT8 opens the door to bigger comfort, more grip, and more capability wrapped in colorways that look as fierce as they feel.
The Seat Stay Advantage
A unique seat stay design balances strength, compliance, and precision handling. The GT8 is built to maximize ride performance while staying true to modern gravel standards and race-ready intent.
