Do you ever want to be able to keep riding, no matter where the path leads? Merida’s Silex series does just that – road bike fit and ride on mountain bike inspired geometry.  Combined with Shimano’s brand-spanking new GRX groupset – taking the best of MTB and road ready for all conditions, and you have a formidable package.

The Merida Silex 400 is an adventure road bike built to tackle bike paths and dirt paths with equal efficiency and control. The Silex 400 is built with a road bike style fit and then paired with wheels, brakes and wider tyres that can go off-road and deliver a crisp riding experience. The Silex 400 is built with a lightweight alloy frame, made from Merida’s proven high-end aluminium (6066) which is extremely light and durable. Using triple butted wall thickness and hydroforming technology the aluminium tubes are tuned to give the best possible stiffness to weight ratio – whilst through-axles stiffen things up from below.

The Merida Silex 400 uses a tapered head tube to give you the ideal level of stiffness and precise steering on the gravel. Double pass welding gives the frame a sharp, carbon-like appearance while the cables are routed internally to maintain that sleek look and keep the cables safe from dirt and moisture. The high-quality alloy frame is combined with a carbon fork to reduce weight and minimise the transfer of vibration from the road.

The Silex 400 is equipped with a 2×10 speed Shimano GRX400 groupset which is made specifically for top-level performance on gravel, providing simple and reliable shifting, while the bike is also equipped with Shimano GRX400 hydraulic disc brakes so that you have control in any conditions, a noticeable improvement over rim brakes. The Merida Silex 400 is a smooth and efficient gravel bike that is ideal for riding into the unknown. With its versatility this bike makes a great commuter as well as its intended purpose as a slick adventure road bike that cane take you anywhere with smooth efficiency.
