Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

Merida Silex 400 Gravel Bike in Grey/Black

Season:2027

Brand:Merida

Code:P-S435

The Merida Silex 400 is an adventure-ready gravel bike designed for the road less travelled, offering everyday versatility and off-road capability.

The Silex concept features modern MTB-inspired geometry with long top and head tubes and a short stem, providing nimble, confidence-inspiring handling. This second-generation frame includes a revised fork design that allows for the installation of a suspension fork without affecting geometry.

Built for adventure, the aluminium frame includes five sets of bottle bosses and rack mounting points, offering multiple luggage-carrying options. The bike features internal routing for dropper posts and dynamo systems, alongside the sleek WIRE PORT cable routing for a clean look. The carbon fork includes additional cargo mounts and internal routing for a dynamo hub.

Equipped with a durable Shimano GRX 2x10-speed groupset and powerful hydraulic disc brakes with 180mm rotors, the Silex 400 is ready for any terrain. The frame provides generous tyre clearance of up to 700x45 mm, or 42 mm when using fenders.

Features:

  • Award-winning aluminium frame with dropped chainstay for 700x45 mm clearance
  • Multiple mounting points for cages, bags, and fenders
  • WIRE PORT internal cable routing for clean aesthetics and bag fitting
  • Carbon fork with cargo mounting points and routing for dynamo hub
  • Relaxed head angle and MTB-style geometry for off-road stability
  • Wide-range gravel-specific Shimano GRX 2x10-speed groupset
