Versatility never goes out of style. The Merida Silex 400 Gravel Bike is an adventure-ready gravel bike that’s equally at home doing a rough commute or winter training laps, thanks to a durable aluminium frame, lightweight carbon fork and huge tyre clearance of 700 x 45 mm – or even 42 mm tyres with fenders. Our MTB-inspired geometry gives you huge confidence off-road, the huge number of mounts mean you’ll be able to carry what you need easily, and the durable Shimano 2x10-speed GRX groupset and brakes will make short work of the ups and downs.
- 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 looks and scuff free 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

Why Buy From Us?
Free servicing, priority workshop and bike box hire
Free servicing, priority workshop and bike box hire
Selling bikes in Glasgow since 1980 — one of the longest-established shops in Scotland.
Built properly. Every bike assembled from scratch by our Cytech Level 2 mechanics, brakes bedded in, greased to suit a Glasgow winter, buddy-checked and test ridden before it’s boxed.
Free 6-week service. Cables stretch and spokes bed in over the first few hundred miles. Bring it back and we’ll re-tension, re-index and check every bolt.
Priority workshop, for as long as you own the bike. We never turn away someone who bought their bike here, however busy we are.
Free bike box hire. A hard-case Bike Box Alan whenever you travel with the bike.
Free changes at the build stage. Saddle, stem, bars, tyres, pedals — far cheaper before the bike is built than after. Add a note to your order at checkout.
Free test rides around Glasgow Green, on as many bikes as you like.
