HOME > BIKES > CYCLOCROSS > S-WORKS CRUX

When we set out to design a new 'cross rig we didn't just want to make another adventure bike with added tyre 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 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 colour)—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 centimetres 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 millimetres of clearance on all sides of a 33mm tyre 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. It's awesome to have a light bike after all but frame weight becomes irrelevant when it's covered in 10 pounds of mud.

The S-Works CruX is also 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 and an S-Works carbon seatpost and handlebars.

  • Our top-of-the-line S-Works FACT 11r carbon frame features our Rider-First Engineeredâ„¢ design, a race-ready 'cross geometry, and comes equipped with thru-axles, 142mm rear spacing, and takes advantage of our highest quality carbon production methods in order to create a bike that's as responsive as it is lightweight.
  • The Win Tunnel Engineered Roval CLX 50 Disc carbon wheelset offers superior aerodynamics, incredible mud-shedding-ability, and a svelte 1415-gram weight.
  • Cross courses are notorious for being cold, muddy, and rainy—and when you can barely feel your fingers, or your rims are so full of mud that slowing down is only a pipe dream, you'll be happy that the S-Works CruX comes spec'd with Shimano Dura-Ace Di2 shifters and powerful hydraulic disc brakes.

Please note that this bike does not come with pedals.
