GR20 - Gravel Adventure
Forwards GR20 Gravel Bike
The Forwards GR20 is our hero gravel bike and all-round bikepacking machine, designed to carry as much gear as you can throw at it. Built for adventure, it delivers confidence, durability, and versatility across gravel roads, mixed terrain, and long-distance rides.
Carbon Frame with Tyre Clearance
The lightweight carbon frame and fork are engineered for strength and endurance. With generous tyre clearance for tyres up to 50mm, the GR20 can accommodate larger tyres for traction and comfort. Multiple mounting points allow racks, bags, and mudguards to be added for fully loaded bikepacking adventures.
Customisation and Personalisation
Each GR20 is individually finished and numbered, giving riders the freedom to create a bike that reflects their style and riding needs. Paint and graphics can be customised, while drivetrain, wheels, tyres, and cockpit setup can all be tailored for performance and comfort. Additional accessories can be added to match the demands of long trips or heavy loads, ensuring the bike works perfectly for your adventure.
Adventure-Ready Performance
Built to perform under load, the GR20 handles confidently whether you’re riding light or fully packed. Its frame, tyre clearance, and mounting points provide stability and control across all terrain, making it a versatile and reliable choice for gravel riding, bikepacking, or long-distance touring.
