2024 Specialized S-Works Crux Frameset

The 2024 Specialized S-Works Crux Frameset represents the pinnacle of lightweight performance in the world of cyclocross and gravel racing. Engineered for riders who want agility, efficiency, and confidence on the toughest courses, it’s the frameset that defines modern all-terrain speed.

Built from Specialized’s premium FACT 12r carbon, this frame delivers an exceptional stiffness-to-weight ratio for explosive power transfer and razor-sharp control. Every detail is designed for competitive advantage, from technical sections and muddy off-camber lines to fast gravel climbs and descents.

With race-ready geometry, the S-Works Crux combines a low bottom bracket and steep head tube angle for precise handling, paired with short chainstays for rapid acceleration. Ample tire clearance up to 47c or 650b x 2.1” ensures versatility across cyclocross and gravel conditions, while fully internal cable routing maintains a sleek, clean aesthetic.

As the lightest gravel frameset in the world, the Crux embodies Specialized’s dedication to minimal weight without compromising durability or capability. Inspired by the ultralight Aethos, it floats up climbs, responds instantly at the pedals, and gives riders the freedom to push beyond traditional race boundaries.

Lightest: Just 725g (S-Works 12r) and 825g (10r), making it one of the lightest gravel frames ever built. Borrowing design breakthroughs from the Aethos, the Crux delivers pure climbing power and unmatched responsiveness.

Capable: Tire clearance up to 47c/650b x 2.1” unlocks true off-road capability. From smooth gravel to deep mud, the Crux adapts to any terrain at full race speed.

Responsive: Reactive and refined, with geometry rooted in cyclocross racing. The Crux feels agile in tight turns yet stable at high speeds, balancing precision with comfort on rough ground.
