Style
Versatility never goes out of style. The SILEX 400 is an adventure-ready gravel bike that's equally at home doing a rough commute or winter training laps, thanks to a durable aluminium frame, lightweight full carbon fork and huge tyre clearance of 700 x 45mm - or even 42mm tyres with mudguards. The MTB-inspired geometry gives you huge confidence off-road, the huge number of mounts mean you'll be able to carry what you need easily, and the durable Shimano 2x10-speed GRX groupset and brakes will make short work of the ups and downs.

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
- Aluminium 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
- Carbon fork with cargo mounting points and routing for dynamo hub
- Relaxed head angle and MTB-style geometry for off-road stability
- Wide-range gravel-specific Shimano GRX 2x10-speed groupset
- Powerful Shimano GRX hydraulic disc brakes

Details
PROLITE 66 TRIPLE BUTTED ALUMINUM
When creating high-end aluminium frames, Merida use the proven PROLITE 66 (6066) aluminium, as it is incredibly light and durable. In addition, it works exceptionally well with our hydroforming technology, allowing us to create complex shapes, featuring triple butted wall thicknesses, an almost carbon-like appearance and the best possible stiffness-to-weight ratio. While lesser alloys might be cheaper, it is the ideal choice for high-performance bicycle frames.

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.
