Versatility never goes out of style. The SILEX 400 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 2×10-speed GRX groupset and brakes will make short work of the ups and downs.
