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 2x10-speed GRX groupset and brakes will make short work of the ups and downs.
The SILEX turns any ride into an adventure, whether you’re on a multi-day gravel bikepacking mission or just taking the fun route to work. The latest version builds on the test-winning pedigree of the original SILEX but adds even more off-road capability, thanks to a slacker head angle and boosted tyre clearance of up to 700x45 mm or even 42 mm with fenders. We've combined that confident mountain bike-inspired handling with all-surface versatility so that it is utterly stable when loaded up with luggage but still fast and fun when you put the hammer down. With carbon and aluminium frame options, there's a SILEX to suit every budget, but all of them share the multiple mounting points, fender racks and other features that lend themselves so well to this drop-bar do-everything machine. We’ve added our sleek WIRE PORT cable routing for improved looks – and fewer cables to catch on with a handlebar bag – and the carbon fibre fork used on all models now has more cargo mounts plus internal routing for a dynamo hub. With the ability to use 1x or 2x drivetrains, you can pick your gearing to suit the task at hand or your own personal preference, opening up a world of opportunity for you and your SILEX.
