The Merida Silex 4000 (Gravel Carbon) 2025 is your gateway to high-performance gravel adventures without the premium price tag. As the winner of the prestigious Taipei Cycle d&i Award 2024, this carbon gravel bike blends innovative design with proven trail and road performance, making it the perfect entry point into Merida’s carbon-framed gravel lineup.
Equipped with a rugged 10-speed Shimano GRX drivetrain and a double chainring setup, the SILEX 4000 provides reliable, climb-anything gearing for a variety of terrain. Its lightweight carbon fibre frame and carbon fork deliver responsive handling and vibration-damping comfort, while the wide 700×45 mm Maxxis Rambler tyres (tubeless-ready) ensure excellent grip and control across dirt, gravel, and asphalt.
The SILEX 4000 shares the same advanced geometry as its higher-end siblings, inspired by mountain bikes for superior off-road stability and control. Whether you’re tackling backcountry trails, loading up for a bikepacking tour, or just riding to work the scenic way, this bike offers balanced handling, confidence, and a truly versatile ride feel.
Multiple mounting points on the frame and fork let you gear up for longer rides with water bottles, cargo cages, and bikepacking bags. The WIRE PORT internal cable routing system keeps cables neatly tucked away and reduces clutter — especially helpful when using handlebar bags. The carbon fork also includes mounts for a dynamo hub and cargo racks.
