The Silex is Merida's modern gravel/adventure bike. Available in a large range of options to suit all needs and budget there is a Silex for anyone ready for the world of drop-bar off-roading.

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 2nd gen frame runs a revised fork design meaning you can swap to a suspension fork without affecting the geometry. 

Silex 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.
