The Merida Silex 4000 Gravel Bike is the ultimate entry-level carbon all-road and gravel bike, ready for back lane adventures, gravel roads, and forest trails. With a CF2 carbon frame, this model is equipped with all the necessary mounting points for luggage, water bottles, fenders, and rear racks. The Carbon CF2 fork enhances ride comfort and steering precision across all terrains, while the Shimano GRX groupset with a gravel-specific 2 x 10, 11-36T gear range excels on both flat sections and long climbs. The Shimano GRX hydraulic disc brakes provide exceptional stopping power, regardless of weather or terrain, and the Maxxis Rambler tyres ensure outstanding grip for off-road rides. Together, these features make the Merida Silex 4000 the most versatile and comfortable road bike Merida has ever produced. Ideal for daily commutes on roads and paths, it effortlessly transitions to weekend gravel grinds, bikepacking trips, or forest trails.
The Silex 4000's geometry draws inspiration from modern mountain bikes, offering a long top tube, a long head tube, and a short stem for a comfortable and nimble ride. The bike's confidence-inspiring handling and renowned comfort make it a favorite among gravel enthusiasts and the comfort-focused road and commuting community. With its sleek design and internal cable routing, the Silex 4000 combines style and functionality, leaving your cockpit uncluttered and clear.
Nano Matrix Carbon
Merida uses Nano Matrix technology to create the strongest and best carbon frames. The carbon fibers are bonded using an epoxy resin with added nanoparticles, increasing impact resistance by up to 40%!
Internal Seat Clamp
The internal seat clamp is more than just a detail; it can save valuable time by reducing turbulence at the top tube, resulting in a faster, more comfortable ride.
X-Taper Headtube
The X-Tapered headtube accommodates a tapered fork, providing superb stiffness and precise, confidence-inspiring handling. With this setup, navigating streets and corners becomes effortless.
