Style
This high-value carbon framed bike is ready for any adventure, with a durable Shimano GRX drivetrain that offers climb-anything ability plus Merida's proven mountain bike-inspired handling for off-road confidence.

The SILEX turns any ride into an adventure, whether you're on a multi-day gravel bikepacking mission or just taking the fun route to work. The latest version builds on the test-winning pedigree of the original SILEX but adds even more off-road capability, thanks to a slacker head angle and boosted tyre clearance.

With carbon and aluminium frame options, there's a SILEX to suit every budget, but all of them share the multiple mounting points that lend themselves so well to this drop-bar do-everything machine. SILEX features sleek WIRE PORT cable routing for improved looks - and fewer cables to catch on with a handlebar bag - and the carbon fibre fork used on all models now has more cargo mounts plus internal routing for a dynamo hub.



Highlights
- Lightweight carbon frame with dropped chainstay for 700x45mm clearance
- Multiple mounting points for cages, bags and fenders
- WIRE PORT internal cable routing for clean looks and scuff free bag fitting
- Full carbon fork with cargo mounting points and routing for dynamo hub
- Relaxed head angle and MTB-style geometry for off-road stability
- Shimano GRX 10-speed gravel specific groupset
- GRX hydraulic disc brakes
- Under-saddle pouch with MERIDA multitool


Details
NANO MATRIX CARBON
A special kind of carbon fibre where extremely tiny, nano-scale particles are added 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.


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
Running the brake and gear cables inside the frame protects them from the elements, gives a clean and neat look and can offer aerodynamic advantages.


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.
