Specialized S-Works Crux frame . The Crux is the world's lightest gravel bike, with ample tire clearance and geometry designed for performance and speed. Now the gravel bike also glows with performance and lightness. The S-Works FACT 12r carbon fiber frame weighing only 725 grams is inspired by the Aethos, Specialized's lightest bike. The result is a gravel bike that climbs with agility, passes nightmarish terrain with ease, and weighs less than your full water bottle. You can fit tires up to 47c or 650b x 2.1" section. Tire clearance is that of the Diverge and allow the CruX to take you anywhere at full speed. The new CruX is agile and responsive. The new performance gravel geometry includes a racing stance as per the good tradition of CruX in cyclocross racing.
