What Our Gearhead Experts Are Saying:"I built up the Crux for fast gravel and long days with big elevation-this frameset absolutely floats on climbs. It's surprisingly responsive on descents too, and the tire clearance is perfect for mixed surfaces. I paired it with electronic shifting and carbon hoops, and it's hands-down the most capable gravel setup I've owned."Gravel enlightenment starts with the S-Works Crux Frameset. Specialized pulled straight from the Aethos playbook to create the lightest gravel frame on Earth-without sacrificing capability or confidence. The Crux was born from a race-winning cyclocross pedigree, now tuned for high-speed gravel exploration with a geometry that balances agility and comfort. This is the platform for riders who demand elite performance, featherlight construction, and day-long rideability. We love the Crux's incredible 47c (700c) and 2. 1in (650b) tire clearance-meaning we're never limited by terrain. From smooth fire roads to chunky alpine gravel, it stays poised and fast. The FACT 12r carbon frame and fork offer incredible power transfer, and the internal cable routing keeps it clean and rattle-free. Whether you're racing, riding epics, or building a dream machine, the Crux sets the standard. Heads up - We do our best to keep bike specs and images current, but occasional component changes can happen without warning-and sometimes the photos might not show the exact build you'll receive.
