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 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, 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. 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 Engineered 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.
Electronic drivetrain systems deliver excellent shifting, easy set up, and solid battery life. Here are the highlights of today’s electronic shifting systems:
Electronic shifting systems use powerful servomotors to rapidly shift the chain. Because microprocessors and sensors constantly monitor every aspect of the system, they shift with precisely and without chain rub.
Many major systems have customizable shifting. Some have the ability to add remote shifters for common riding positions, and some even allow you to change the functions of the shifting buttons.
Electronic groupsets are responsive and consistent. There are no cables to stretch and wear out, so you get a flawless shift every time. The added bonus is you’ll never have to replace a derailleur cable ever again.
