When we set out to design a new cross rig, we didnt 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 were proud to say that this S-Works CruX takes the legacy to a whole different level.
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 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, isnt useful in a cross race if it isnt 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 youre 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. And along with clearance, select S-Works models feature hydrophobic, mud-shedding paint that reduces the ability for mud to cling to the frame. Its awesome to have a light bike, after all, but frame weight becomes irrelevant when its covered in 10 pounds of mud.
The S-Works CruX is also specd with the lightest components possible. Along these lines, it features a 1x groupset with a mix of Shimanos Dura-Ace and XTR components, lightweight, aerodynamic, and mud-shedding Roval CLX 50 clincher disc wheels, and an S-Works carbon seatpost and handlebars.
