The Silex is Merida's modern gravel and adventure bike, available in a wide range of builds to suit every need and budget, so there's a Silex for anyone ready to explore the world of drop-bar off-roading.
The Silex 400 offers outstanding value, with a high-quality aluminium frame and full carbon fork that combine off-road-ready handling with all-road versatility. Its MTB-inspired geometry pairs a long top tube and head tube with a short stem for nimble, confident handling on loose surfaces, and the fork has mounts and routing for a dynamo hub.
Shimano's GRX groupset takes care of shifting and braking, with a 2x10 drivetrain offering a wide 46-30T and 11-36T gear range and powerful GRX hydraulic disc brakes with 180mm rotors. Maxxis Rambler 45mm tyres on tubeless-ready rims add grip and comfort, and multiple mounts let you carry bags, bottles and mudguards.
