Merida Silex 400 2022

Merida Silex 400 at Cycle Zone — adventure-ready gravel control with Shimano GRX

The Merida Silex 400 is a versatile gravel bike built for long days on dirt roads, scenic detours and light bikepacking. An aluminium SILEX LITE frame pairs a carbon fork with stable, MTB-inspired geometry to give you confident handling on loose surfaces without feeling sluggish on tar. With generous tyre clearance and loads of mounting points, it’s the kind of all-rounder that turns any route into an adventure.

Shimano’s proven GRX 2×10 drivetrain delivers crisp shifting and a wide range for steep climbs and fast flats, while powerful hydraulic disc brakes keep you in control when gradients or weather turn tricky. Thru-axles front and rear add stiffness and precise tracking, and internal cable routing keeps things tidy for easy maintenance and clean looks.

Whether you’re exploring farm roads, commuting during the week, or packing soft bags for a gravel weekend, the Silex 400’s blend of comfort, control and efficiency makes it a smart, future-proof choice. Find expert sizing and setup at Cycle Zone in Rustenburg.

Premium Features for Real-World Gravel

The Silex 400 is designed around real adventure needs: a carbon fork to cut road buzz on long dirt sections, internal routing to protect cables from dust and mud, and a threaded BSA bottom bracket for straightforward servicing. The through-axle wheel standard keeps handling sharp when you’re loaded with bags, while tubeless-ready rims and gravel tyres let you drop pressures for grip without inviting punctures.

Fit and control are dialled from the start thanks to a flared gravel bar for stability in the drops and size-specific cockpit dimensions to keep your posture relaxed but efficient. With tyre clearance up to 45C, you can tailor the feel from fast-rolling to plush and planted as your riding evolves.
