Merida Silex 4000 II1 2024

Ready for adventures of any size. The SILEX 4000 is the entry into the carbon fiber frame range, combining the lightweight frame and fork with high-value components such as the utterly durable 10-speed Shimano GRX drivetrain with a dual crankset for the ability to climb any slope. Robust tubeless-ready Maxxis Rambler tires and mountain bike-inspired geometry provide predictable grip and a well-planted stance to the terrain on any surface.

The SILEX turns any trip into an adventure, whether you're taking part in a multi-day bikepacking trip or simply taking the most fun route to work. The latest version builds on the winning pedigree of the original SILEX but adds even more off-road capability, thanks to a more open steering angle and increased tire clearance of up to 700x45 mm or 42 mm when fenders are installed. With carbon and aluminum frame options, there is a SILEX to fit every budget, but they all share the multiple mounting points, fender mounts and other features that lend themselves so well to this all-rounder bike. WIRE PORT cable routing has been added for a cleaner, more modern design, and the carbon fiber fork used on all models now has multiple mounts for cargo and an internal passage set up for possible dynamo. With the ability to use 1x or 2x drivetrains, you can choose your drivetrain based on the task at hand or your personal preferences, opening up a world of opportunities for you and your SILEX.

Technologies

X-TAPER Headtube
The X-Tapered headtube provides space to mount a tapered fork. Tapered forks offer exceptional stiffness and precision and provide confidence-inspiring steering.

Internal Cable Routing
On the majority of our frames, we run the gear and brake cables and hoses through the frame. The cables enter and exit the frame through smooth sockets, or we use one of our other systems like SMART ENTRY or WIRE PORT to be routed through. Running the cables inside the frame protects them from the elements, gives a clean and neat look and can offer aerodynamic advantages.

DI2 READY
Shimano's Di2 electronic shifting system offers fast, smooth and reliable shifting. In particular, in the road world, it has proven itself as the primary choice when top performance is at the top of the agenda. With that in mind, we have a broad selection of performance road frames that are Di2 READY and can accommodate the electrical cable, battery and other little tweaks that the system requires.

Nano Matrix Carbon
NANO MATRIX CARBON is a special kind of carbon fibre where we add extremely tiny, nano-scale particles to the resin that binds the individual carbon fibres together. These then work on a molecular level to protect them from damage. It’s so effective that it can actually increase the finished carbon fibre’s impact resistance by up to 40%, allowing us to build stronger and lighter composite frames that result in a faster and tougher bike.

AWS Anti Wrinkle System
This is a method we use to manufacture our carbon fibre frames. First, the carbon fibre that makes up the frame is laid around special formers. We then use a bladder to compress the layers against the outside of the frame mould, giving a smooth and wrinkle-free internal finish, removing any voids in between the layers of carbon that can cause potential weak points, resulting in a stronger, lighter frame.

F-Mount
'F-Mount-equipped bikes have built-in fender fittings (some bikes require model-specific fenders), making mounting quick and easy.

Disc Cooler
A forged aluminum component under the front and/or rear caliper that allows heat to dissipate through CNC-milled cooling fins. Tests show that temperatures are reduced by about 35 percent and cooling times are shortened, optimizing brake performance.

Internal Clamp
When every second counts, the smallest of details can make the difference between winning and losing, so we look at every aspect of our frames to make them as sleek as possible. By using a seat post clamping mechanism that secures the post with a wedge inside the frame itself, we minimise the turbulence and potential drag while keeping post height adjustment simple, giving a frame that is more aerodynamic and also better looking.

Removable F-Mount
A bridge on the removable pendants can be fitted for neater and safer mounting of rear fenders, but removed for more mud clearance and a cleaner appearance.

Wire Port
MERIDA has designed covers that allow all control cables to enter the frame through the headset, creating a clean, uncluttered appearance without making structural changes to the frame. Depending on the model, the cables pass completely inside (including bar and stem) or semi-integrated where the cables enter the frame under the stem.
