Where Gravel Gets Interesting

The GT8 is made for the rides that don't follow a route. It was designed to master uneven terrain, unknown turns, and long mixed surface days where stability, speed, and confidence all matter at once. Confident handling and long distance comfort make it a bike that encourages exploration without limits, and wherever the road disappears, the GT8 keeps going.

Clearance That Changes the Ride

With up to 55mm of tyre clearance, the GT8 opens the door to more comfort, more grip, and more capability. It comes fitted with Continental Terra Trail 700x45C tyres, with room to go wider when the terrain calls for it.

The Seat Stay Advantage

A unique seat stay design balances strength, compliance, and precision handling. The GT8 is built to maximise ride performance while staying true to modern gravel standards and race ready intent. The Toray T-800 carbon frame is UDH compatible, and the matching carbon fork uses a 100x12mm thru axle.

Shimano GRX Di2 Precision

The GT8 runs a Shimano GRX 717 Di2 groupset, including the GRX RX717 shifters and rear derailleur, giving you crisp, reliable electronic shifting on rough ground and long climbs. A Shimano CS-M6100-12 cassette (10-51T) provides a huge gear range, and Shimano GRX BR-RX715 hydraulic disc brakes with 160mm rotors front and rear deliver strong, consistent stopping power in all conditions.

Power Meter and Smart Security Built In

The Branta alloy crankset (40T, narrow wide teeth, 24mm steel spindle) features an integrated power meter, giving you training data straight out of the box. It also includes Apple Find My anti-theft technology, adding an extra layer of peace of mind when you're riding far from home.

Carbon Wheels, Carbon Cockpit

The Branta C45 Gravel carbon wheelset, with stainless steel spokes, adds lightweight, aerodynamic performance to the build. A Branta carbon handlebar and stem, a 27.2mm carbon seatpost, and a Fizik Terra Argo X7 saddle round out a cockpit made for hours in the saddle. In frame storage and accessory mounting points on the frame and fork give you room to carry what you need for longer adventures.

Backed by over 40 years of family owned expertise, every X-LAB GT8 from bikes.com.au comes with 12 months of unlimited servicing and extended warranty, so you can explore with total confidence.
