S-Works CruX Frameset

2018 S-Works CruX Frameset

The S-Works CruX frameset is a 'cross-optimized warrior. With its S-Works FACT 11r carbon frame, flat disc brake mounts, and S-Works Fact carbon seatpost, it's ready to be built up exactly how you want it—you have the foundation for a real course crusher.

Beginning with the frame, we implemented our Rider-First Engineered™ technology that was first introduced on our Tarmacs. Using size-specific tubes and layups, this technology allows the CruX to feature the same ride characteristics across every size in the range. Not only this, but it also allowed us to significantly drop the frame weight, so the CruX now comes in around a low 900 grams for a 56cm—over 400 grams lighter than the previous frameset. A light and stiff frame, alone, isn't useful in a 'cross race if it isn't compliant, however, which is why the new CruX also combines stiffness and compliance in all the right places. And to assist with the latter, we lowered the seat collar by two centimeters for more exposed seatpost and, therefore, cushion for big hits.

We also know that cyclocross races are often won in the corners and over the barriers, which is why the CruX geometry takes this into account. The top tube has been design for easy shouldering when you're hopping off to clear barriers, as it features a large opening to the front triangle and a flat bottom. For stability in the corners and on off-camber sections, the geometry has a low bottom bracket and a sharp front end. This combination also helps to initiate corners, regardless of the terrain.

With maximum mud shedding ability in mind, we included eight millimeters of clearance on all sides of a 33mm tire, providing plenty of clearance for muddy conditions. It's awesome to have a light bike, after all, but frame weight becomes irrelevant when it's covered in 10 pounds of mud.
