GT8

X-LAB GT8 Gravel Bike

The GT8 is a gravel bike with a frame and fork made from Toray T800 carbon. The frame is UDH-compatible, and the fork has a 100x12 mm thru-axle. It also offers tyre clearance of up to 55 mm. A special seatstay design balances strength, comfort and precise handling. The storage box in the down tube holds tools and snacks. There are also mounting points for accessories on the frame and fork.

Technical Details and Features

Shifting is handled by Shimano GRX Di2 Wireless. The rear derailleur and shifters belong to the GRX 717 Di2 series. The cassette ranges from 10 to 51 teeth. This gives you a wide gear range with plenty of reserves, even on steep climbs and when carrying luggage.

The power meter is built right into the crankset. It's a Branta aluminium crankset with 40 teeth and a 24 mm steel spindle. It also comes with Apple Find My anti-theft technology. The bottom bracket is a T47.

The bike rolls on Branta C45 GT Carbon wheels. The stem and gravel handlebar also come from Branta and are made from carbon. The carbon seatpost has a diameter of 27.2 mm. The saddle is the Fizik Terra Argo X7. The maximum permissible total weight is 110 kg, including rider and luggage.

Use Cases and Benefits

The manufacturer describes the GT8 as a versatile gravel bike for adventure rides, gravel races and short bikepacking tours. It suits both new and experienced gravel riders. The generous tyre clearance lets you run wide tyres with plenty of grip and comfort on Swiss gravel tracks, forest roads and mountain pass routes. With the integrated power meter, you can train with watt data on every ride, without fitting any extra parts.
