Merida SILEX 400 - Gravel Bike - 2026 - warm slate grey

Versatility for everyday use and an adventure-ready attitude.

Versatility never goes out of style. The Merida SILEX 400 is an adventure-ready gravel bike that, thanks to its sturdy aluminum frame, lightweight carbon fork, and ample tire clearance for 45 mm-wide tires—42 mm with fenders—is equally suited for rough commutes or winter training. The geometry, inspired by Merida MTBs, gives you plenty of confidence off-road. Thanks to the numerous mounting options, you can easily bring along everything you need. The sturdy Shimano 2x10-gear GRX groupset and brakes make short work of climbs and descents.

The SILEX turns every ride into an adventure, whether you’re tackling a multi-day gravel bikepacking tour or simply want to take the most scenic route to work. With multiple test wins and rave reviews from the trade press, it remains absolutely stable even with luggage, yet is still fast and fun when you open the throttle. Thanks to the carbon and aluminum frame options, there’s a SILEX for every budget. All models feature multiple mounting options for gravel cages, bottle cages, and accessories, as well as other features that make this all-round drop-bar bicycle so versatile.

Thanks to the elegant WIRE PORT cable routing, the bicycle boasts a clean look. Additionally, it doesn’t interfere with mounting a handlebar bag. The carbon fork used on all models features multiple mounting points as well as internal cable routing for a hub dynamo. Thanks to the option to use 1x or 2x drivetrains, you can choose your gear ratio based on specific requirements or personal preferences. The SILEX opens up a wide range of possibilities.
