  • The SILEX 400 is simply crying out for some demanding cycling adventure away from pristine tarmac as well as fully laden bikepacking excursions. The stable handling of the triple butted aluminium frame, paired with our full carbon gravel fork and equipped with Shimano's gravel-specific GRX groupset, means the 400 is super capable on the way up but also on the way back down again. And that is not just down to the fully hydraulic brakes. With the SILEX 400, every road is yours.

    "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 our most comfortable and versatile road bike ever. With its modern MTB inspired geometry, long top and head tubes and short stem, it offers nimble, confidence-inspiring handling. While often seen on extended gravel and rough road outings, as well as bikepacking trips, the SILEX also found a strong following in comfort-orientated road riding connoisseurs as well as commuters and city traffic weavers. The more rugged 650b wheeled alternative to the 700c SILEX has managed to obtain multiple test wins as well as comfort awards, and is coming back in the form of the fully loaded and wirelessly shifted SILEX+ LIMITED. The 'classic' 700c SILEX also impressed the press with the 400 securing a test win in Cycling Plus, being certified as having a 'huge fun factor', 'superb riding position' and 'brilliant off-road handling'.

    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.
