Gravel racing rewards efficiency above all else, and the S-Works Crux delivers on that premise with a FACT 12r carbon frame weighing 725 grams. Specialized applied the same layup techniques and engineering approach that produced the Aethos to create a gravel chassis that disappears beneath you on long climbs and responds instantly when you stand on the pedals. The Rider First Engineered construction varies tube shapes and carbon layup schedules across frame sizes, so each size rides with the same intended stiffness-to-compliance ratio rather than simply scaling a single design up or down.

The geometry draws from the Crux's cyclocross heritage while stretching the wheelbase and adjusting the head tube angle for stability at sustained gravel speeds. Stack and reach numbers across the size run suggest a position that keeps your torso low enough for aerodynamic efficiency without cramping your hip angle on multi-hour efforts. The threaded bottom bracket shell accepts a SRAM DUB BSA unit and offers straightforward bearing replacement without specialized tools or press-fit complications. Tire clearance accommodates up to 47c rubber on 700c wheels or 2.1-inch tires on 650b, matching the versatility of endurance-focused gravel platforms.

The Universal Derailleur Hanger dropout brings compatibility with current and future SRAM transmission systems while positioning the derailleur in a protected location. In the event of a crash or mechanical issue, a replacement hanger costs far less than a new frame. The flat-mount disc brake interface and 12mm thru-axles front and rear provide stiff, consistent braking under load.... Read More
