Product Details

When we set out to design a new 'cross rig, we didn't just want to make another adventure bike with added tire clearance—we knew we had to create a purebred racing steed that was fast, confident, lightweight, and rides like no other 'cross bike out there. And sure, with multiple Cyclocross World Championships to its name, the Crux has more than proven itself in 'cross, but we're proud to say that this Crux takes the legacy to a whole different level. The S-Works Crux is spec'd with the lightest components possible. Along these lines, it features a 1x groupset with a mix of Shimano's Dura-Ace and XTR components, lightweight, aerodynamic, and mud-shedding Roval CLX 50 clincher disc wheels, our S-Works Power Cranks power meter, and an S-Works carbon seatpost and handlebars.

Starting 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 scant 900 grams for a 56cm (*dependent on frame size and color)—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 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 designed 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. After all, frame weight becomes irrelevant when it's covered in 10 pounds of mud.

Oh yes

The Crux is just about the perfect all around bike. With a second set of road wheels, I can do road, Cx, and gravel. Smooth, stable, classic lines, and no gimmicks like built in suspension, wired geometry, or proprietary components to trick you up for future component upgrades. This could be the best all around bike ever made. I'm sorry for potential Specialized customers that it is not marketed this way.
