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 4000 puts a lightweight CF2 carbon frame within easier reach.
Rather than taking a road or cyclocross bike and reworking it, the Silex was designed from the ground up with modern MTB-inspired geometry: a long top tube and head tube paired with a short stem for nimble, confidence-inspiring off-road handling. This second-generation frame uses a revised fork design, so you can swap to a suspension fork without affecting the geometry, and the carbon fork has mounts and routing for a dynamo hub.
Silex frames have five sets of bottle bosses and can run an internally routed dropper post, giving you plenty of options for longer adventures. The 4000 build pairs a Shimano GRX 2x10 drivetrain and GRX hydraulic disc brakes with 180mm rotors with Reynolds G30 rims, Maxxis Rambler 45mm tyres and a carbon seatpost.
