Where Gravel Gets Interesting

The GT8 is made for the rides that don’t follow a route, with uneven terrain, unknown turns, and long mixed surface days. Stability, speed, and confidence all matter at once, and the GT8 is built to deliver all three.

T800 Carbon Frame and Fork

The GT8 uses a T800 carbon frame with a matching carbon fork and a 100x12mm thru axle. A 27.2mm carbon seatpost and a Fizik Terra Argo X7 saddle round out a setup made for long days on rough roads.

Shimano GRX Shifting with a Wide Gear Range

A Shimano GRX715 shifter (ST-RX717) and rear derailleur (RD-RX717) work with a Shimano CS-M6100-12 cassette (10-51T) and a Shimano CN-M6100 chain. The huge gear range gives low gears for steep, loose climbs and enough top end for fast gravel straights.

Power Meter Crankset Built In

The Branta aluminium power meter crankset has a 40T narrow wide chainring, which helps keep the chain secure over rough ground, and a 29mm aluminium spindle with a T47 29mm bottom bracket. With the power meter built in, you get training data straight out of the box without buying a separate unit.

Carbon Gravel Wheels and Wide Tyres

The Branta C45 Gravel carbon wheelset with steel spokes gives a light, strong wheel for mixed terrain. Continental Terra Trail 700x45C tyres add grip and cushioning on gravel, dirt, and tarmac alike.

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.
