The Merida Silex Carbon is a premium, lightweight gravel bike engineered for riders who demand ultimate off-road compliance, long-distance comfort, and high-performance adventure. Upgrading to a world-class full carbon frame and fork, this model features a ground-up design inspired by modern mountain bike geometry.
By pairing longer top and head tubes with a short stem, it delivers exceptionally nimble, stable, and confidence-inspiring handling on technical loose gravel and rugged singletrack. The pure racing pedigree of the Silex concept was proven globally when Matej Mohoric secured the Gravel World Championship title on it. This second-generation carbon frame features an updated fork design layout, allowing you to swap to a front suspension fork down the line without altering the bike’s geometry.
Completely optimized for serious bikepacking and back-road touring, the carbon frame boasts five independent sets of bottle bosses, integrated gear mounts, and full compatibility for internally routed dropper seatposts and advanced dynamo lighting setups.
