The Silex was a ground up design project. Rather than taking a road or cyclocross bike and re-jigging the recipe, the starting point for the Silex was modern MTB inspired geometry; long top and head tubes and a short stem, offering nimble, confidence-inspiring handling.

At launch, it was hailed as the most comfortable and versatile bike we had ever made. The cycling press loved it too: “exceptional ride quality” (Cycling Plus), “a highly versatile bike” (IMB), “the best bike of this genre” (Offroad CC).

There's a certain beauty in just riding without watching the time, heading wherever you feel the urge. For those rides, the test and award-winning Silex makes total sense.

The bike has five sets of bottle bosses and rack mounting points offering multiple luggage carrying options.

All Silex models are equipped with powerful hydraulic disc brakes. Calipers are mounted on the chainstay for better dissipation of braking forces using the flat-mount standard for a neat, flush fit. Calipers sit on top of CNCd aluminium Disc Cooler fins, reducing operating temperatures by up to 35%; particularly important when running fully loaded.

PROLITE 66 TRIPLE BUTTED ALUMINUM

When creating high-end aluminium frames, we use our proven PROLITE 66 (6066) aluminium, as it is incredibly light and durable. In addition, it works exceptionally well with our hydroforming technology, allowing us to create complex shapes, featuring triple butted wall thicknesses, an almost carbon-like appearance and the best possible stiffness-to-weight ratio. While lesser alloys might be cheaper, it is the ideal choice for high-performance bicycle frames.

HFS - HYDRO FORMING SYSTEM

‘C-Mount’ equipped bikes have the fixing points for a rear rack already integrated (some bikes require model specific rear rack), making fitting fast, simple and reliable.

X-TAPER HEADTUBE

Steering precision is vital to safe and confident handling, and the X-TAPER HEADTUBE allows us to significantly boost this precision. A larger headset diameter at the bottom paired with a smaller one at the top helps to deal with the strains modern riding and equipment can put on the headtube, all without adding unnecessary weight. It allows tapered forks to be fitted with ease and delivers precise and confidence-inspiring steering.

SMOOTH WELDING

This is a process we use to give a nice flat finish to our welds instead of the scaled, 'stack of coins' effect TIG welded joints often have. The welder uses the welding torch to go over the joint twice, helping to smooth out the filler material. It takes a lot of skill to do this, but it delivers strong and smart-looking frames that have the appearance of a carbon fibre frame at first look.

INTERNAL CABLE ROUTING

On the majority of our frames, we run the gear and brake cables and hoses through the frame. The cables enter and exit the frame through smooth sockets, or we use one of our other systems like SMART ENTRY or WIRE PORT to be routed through. Running the cables inside the frame protects them from the elements, gives a clean and neat look and can offer aerodynamic advantages.

DOWN TUBE EXIT

DOWN TUBE EXIT is a feature seen on some of our frames with internally routed cables. By slightly overlapping the downtube where it connects to the bottom bracket, it leaves a small space that allows cables to exit easily. This means they are easily accessible for routine maintenance or replacement, but it prevents excessive movement and noise that can cause wear and distraction.

F-MOUNT

Being able to turn your bike into an all-weather commuter that has mudguards and other fittings can be a real plus, in particular when riding on wet and perhaps muddy roads and tracks on a regular basis. To make fitting easy, some of our bikes are F-MOUNT equipped. These integrated fittings mounts make adding mudguards fast and simple. Please note that some bikes require model-specific mudguards.

C-MOUNT

Similar to our F-MOUNT, where various fixing points for mudguards are part of the frame offering, the C-MOUNT equipped bikes have the fixing points for a rear rack already integrated, making fitting fast, simple and reliable. The C-MOUNTS are an additional feature that improves the day-to-day versatility by adding loading capacity to your bike, ideal for commuting and shopping trips. Please note that some bikes require model-specific rear racks.
