Merida Silex 8000 II1 bike 2025

Solo bikepacking adventures, multi-day races or simply riding kilometres in all conditions, all year round. The SILEX 8000 is designed to be as capable as an off-road mountain bike, but with all the versatility the adventure gravel bike is known for. The latest gravel-specific Shimano GRX Di2 2x12-speed gearbox offers a wide range of close ratios with lightning-fast shifts in all conditions, while the Easton EC70 AX carbon fibre wheels are strong and responsive. It is ready for adventure, every day.
The SILEX turns every ride into an adventure, whether you're tackling a multi-day bikepacking trip or simply the most fun route to work. With numerous test wins, praise from the press, industry awards and even a world title, the SILEX takes the off-road capability of gravel bikes to new levels, thanks to a more open steering angle and greater wheel clearance for tyres up to 700x45 mm or even 42 mm with mudguards. Merida has combined that confident mountain bike-inspired handling with all-terrain versatility, making it absolutely stable when loaded with luggage, but still fast and fun when you decide to push. With carbon and aluminium frame options, there's a SILEX for every budget, but they all share the many attachment points for panniers, water bottles, accessories and other features that make this gravel bike so versatile. Merida has added the WIRE PORT cable routing system for an improved look and fewer exposed cables, and the carbon fibre fork used on all models now has more load mounts and an internal hub-dynamo slot. With the option of 1x or 2x drivetrains, you can choose the gear ratio that best suits your personal preferences, opening up a world of opportunities for you and your SILEX.

X-Taper headtube

Steering precision is vital to safe and confident handling, and the X-TAPER HEADTUBE allows us to significantly boost this precision. A larger headset diameter at the bottom paired with a smaller one at the top helps to deal with the strains modern riding and equipment can put on the headtube, all without adding unnecessary weight. It allows tapered forks to be fitted with ease and delivers precise and 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

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

Used on our carbon fibre road and gravel bikes, DISC COOLER is a finned piece of forged aluminium that sits between the brake calliper and frame. The aluminium piece helps to draw heat from the braking system and radiates it away quickly. It reduces the temperatures by up to 35% and helps to keep your brakes working at their best for improved control and performance on long descents and under heavy braking.

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.

Wire Port

MERIDA designed headsets that enable all control cables from the handlebar to enter the frame through the headset cover, creating a clean and uncluttered look, allowing for a lighter, stronger and more aerodynamic frame structure than with conventional cable ports. Depending on the model, the cables are run completely internally (including the bar and stem) or semi-integrated, where the cables enter the frame underneath the stem.
