MERIDA SILEX 400 Bike 2027 – Gravel Bike
Take your cycling further with the MERIDA SILEX 400 2027, a versatile gravel bike built for adventure, everyday riding and exploring beyond the tarmac. Combining a durable aluminium frame, lightweight carbon fork and gravel-specific Shimano GRX components, the SILEX 400 delivers confident handling and all-road versatility for cyclists who want to discover new routes.
Built for Gravel Adventures and Everyday Riding
Whether you're tackling gravel tracks, exploring country lanes, commuting to work or planning a bikepacking trip, the MERIDA SILEX 400 is designed to adapt to your riding ambitions. Its mountain bike-inspired geometry offers stable, confidence-inspiring handling on rougher terrain, while its drop handlebars provide a versatile riding position for longer journeys.
The SILEX Lite II aluminium frame balances durability with practical everyday performance. Paired with the MERIDA SILEX II CF2 carbon fork, it creates a capable gravel bike ready for mixed surfaces, from smooth roads to challenging off-road routes.
Shimano GRX 2x10-Speed Gravel Gearing
The Shimano GRX 400 2x10-speed groupset provides dependable gear changes and a wide range of ratios for tackling varied terrain. With a Shimano GRX 600 chainset featuring 46/30-tooth chainrings and an 11–36-tooth cassette, the MERIDA SILEX 400 offers versatile gearing for rolling countryside, steep climbs and faster stretches of road.
Shimano GRX hydraulic disc brakes deliver controlled braking performance, helping you manage descents and changing conditions with greater confidence.
Wide Gravel Tyres and Confident Handling
Equipped with 700c wheels and 45mm gravel tyres, the MERIDA SILEX 400 is designed to handle uneven surfaces while maintaining versatility for everyday riding. The frame accommodates tyres up to 700 x 45C, with clearance for 42mm tyres when using mudguards, depending on the final setup.
Its stable geometry makes it an excellent option for riders who want to venture off the beaten track without sacrificing the practicality of a capable road-going bike.
Ready for Bikepacking and Longer Journeys
Planning a weekend escape or a multi-day cycling adventure? The SILEX 400 features multiple mounting points for water bottles, compatible luggage and accessories, making it easier to customise your bike for longer rides. Internal cable routing gives the bike a clean appearance and helps reduce interference with compatible handlebar bags.
From daily commutes and winter training to gravel exploration and bikepacking adventures, this versatile MERIDA gravel bike is designed to make every ride an opportunity to explore.
