The S-Works Cru X frameset is a cross-optimized warrior. With its S-Works FACT 11r carbon frame flat disc brake mounts & S-Works Fact carbon seatpost its 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 & layups this technology allows the Cru X 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 Cru X now comes in at a scant 900 grams for a 56cm—over 400 grams lighter than the previous frameset. A light & stiff frame alone isnt useful in a cross race if it isnt compliant however which is why the new Cru X also combines stiffness & compliance in all the right places. & to assist with the latter we lowered the seat collar by two centimetres for more exposed seatpost & therefore cushion for big hits. We also know that cyclocross races are often won in the corners & over the barriers which is why the Cru X geometry takes this into account. The top tube has been design for easy shouldering when youre hopping off to clear barriers as it features a large opening to the front triangle & a flat bottom. For stability in the corners & on off-camber sections the geometry has a low bottom bracket & 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. 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. Our top-of-the-line S-Works FACT 11r carbon frame features a race-ready cross geometry & comes equipped with thru-axles 142mm rear spacing & takes advantage of our highest quality carbon production methods in order to create a bike thats as responsive as it is lightweight. The internally routed S-Works FACT carbon disc fork features a thru-axle design that increases steering response & rider input for the tight turns & the all-out efforts cross demands. The S-Works seatpost is constructed from our highest quality FACT carbon fibre.FRAMES-Works FACT 11r carbon Rider-First Engineered™ 1-3/8&34; lower bearing 12x 142mm thru-axle flat mount disc OSBBFORKS-Works FACT 11r carbon 12x 100mm thru-axle BOTTOM BRACKETOSBB Ceramic Speed bearings SHIFT LEVERSC-clips for bottom bracket shell SEATPOSTS-Works FACT carbon 20mm offset
