Merida Silex 400 Gravel Bike in Warm Slate Grey/Black

Season:2026

Brand:Merida

Code:P-R583

The Silex remains all about the road less travelled, the spirit of adventure and camaraderie. The new Mission platform takes on the role of racing.

This is not to say the Silex was a slouch off-road; a week before its launch, Matej Mohoric won the 2023 Gravel World Championships!

The Silex concept was a ground-up design that, rather than taking a road or cyclocross bike and re-jigging the recipe, started with modern MTB-inspired geometry; long top and head tubes and a short stem, offering nimble, confidence-inspiring off-road handling. This second-generation frame runs a revised fork design, meaning you can swap to a suspension fork without affecting the geometry.

All frames have five sets of bottle bosses. The aluminium frame has rack mounting points, offering multiple luggage carrying options for any adventure, and has the ability to run internal routed dropper posts and even dynamo systems.

All Silex (except the 200) feature powerful hydraulic disc brakes and 180mm rotors. Calipers are mounted on the chainstay for better dissipation of braking forces using the flat-mount standard for a neat, flush fit. On carbon models, calipers sit on CNCd aluminium Disc Cooler fins, reducing operating temperatures by up to 35%; particularly important when running fully loaded.
