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.

Estimated Delivery & Collection Dates are given on Pre-Order and Pre-Launch products. They are for indication purposes only and can change at any time without notice.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Merida Silex 400 Gravel Bike in Oak Bork/Earth Powder

Season:2026

Brand:Merida

Code:P-R374

The Silex remains all about the road less travelled, the spirit of adventure and camaraderie. The new Mission platform takes on the role of racing.

This is not to say the Silex was a slouch off-road; a week before its launch, Matej Mohoric won the 2023 Gravel World Championships!

The Silex concept was a ground-up design that, rather than taking a road or cyclocross bike and re-jigging the recipe, started with modern MTB-inspired geometry; long top and head tubes and a short stem, offering nimble, confidence-inspiring off-road handling. This second-generation frame runs a revised fork design, meaning you can swap to a suspension fork without affecting the geometry.

All frames have five sets of bottle bosses. The aluminium frame has rack mounting points, offering multiple luggage carrying options for any adventure, and has the ability to run internal routed dropper posts and even dynamo systems.

All Silex (except the 200) feature powerful hydraulic disc brakes and 180mm rotors. Calipers are mounted on the chainstay for better dissipation of braking forces using the flat-mount standard for a neat, flush fit. On carbon models, calipers sit on CNCd aluminium Disc Cooler fins, reducing operating temperatures by up to 35%; particularly important when running fully loaded.
