The Merida Silex 400 Gravel Bike is an all-road and gravel bike that comes ready for back lane adventures, gravel roads, and forest trails. With the same lightweight aluminium frame as more expensive models, this bike comes with all the fixing points for luggage, water bottles, fenders, and rear racks meaning it is ready for whatever adventure you want to throw at it. The Carbon CF2 fork increases ride comfort and precision in your steering no matter the terrain, while the gravel specific 2 x 10, 11-36T gear range of the Shimano GRX gearset is perfect for both faster flat sections and long climbs. The gravel-specific Shimano GRX hydraulic disc brakes offer superior stopping power no matter the weather or terrain, and the Maxxis Rambler tyres (with clearance to install up to 42mm tyres!) offer great grip for offroad rides. All of this combines to make Merida's most versatile and comfortable road bike ever. Not only will it feel at home on roads and paths and on your daily commutes, but it can seamlessly transition to those weekend gravel grinds, bikepacking trips or forest trails. 

The Silex 400's geometry draws inspiration from modern mountain bikes to create a bike that is amazingly comfortable and incredible nimble with a long top tube and head tube and a short stem. The Silex has confidence-inspiring handling in spades and due to its renown for comfort, not only is it a popular bike amongst the gravel crowd, but it also has a strong following from the comfort-focused road and commuting community. Aside from comfort and practicality, the Silex 400 offers amazing style with its sleek design, and internal cable routing leaving your cockpit uncluttered and clear. All of this forms to make a versatile bike that looks and feels amazing. 

Hydroformed Tubes

Using their Hydro Forming System, Merida creates tubes that are strong yet lightweight. The tubes are inserted into a negative mold and a hot emulsion of water and oil is passed through them at pressure which enables them to be formed into complex shapes while still retaining strength.

Prolite 66 Triple Butted Aluminium

Using high-end 6066 aluminium and triple butted wall thicknesses, this frame offers strength and durability without excess weight. The hydroforming technology helps to tune the aluminium tubes to give the best possible stiffness to weight ratio.

X-Taper Headtube

The X-Tapered headtube on this bike provides room for a tapered fork to be fitted. Tapered forks provide superb stiffness and precise confidence-inspiring shifting, with this setup you'll be able to navigate streets and corners with ease!
