Weighing less than many road bikes yet offering massive tire clearance and race-proven gravel geometry, the Crux blurs the line between gravel, cyclocross, and road performance. It’s designed to climb effortlessly, accelerate instantly, and stay composed when the terrain turns rough, making it the ultimate choice for competitive gravel racing and fast, adventurous riding.

Key Benefits for Riders

725g S-Works FACT 12r Carbon Frame for Unmatched Efficiency

At the heart of the Crux is a 725-gram S-Works FACT 12r carbon frame, making it the lightest gravel bike frame in the world. Drawing inspiration from the ultra-light Aethos, this frame delivers exceptional stiffness-to-weight efficiency. The result is a bike that rockets uphill, responds instantly to accelerations, and feels effortless over long distances, even on punishing terrain.

Massive Tire Clearance for True Gravel Capability

With clearance for up to 47c tires or 650b x 2.1, the Crux offers Diverge-level capability in a significantly lighter and more race-focused package. This allows you to run higher-volume tires for improved traction, comfort, and control on rough gravel, loose surfaces, and chunky backroads, all without dulling the bike’s lively handling.

Performance Gravel Geometry With Race DNA

The Crux features performance gravel geometry inspired by Specialized’s cyclocross heritage. It’s nimble and reactive at the pedals, stable at speed, and composed through technical corners. This geometry keeps you efficient and aggressive when racing while remaining comfortable enough for long gravel events and all-day adventures.

SRAM RED XPLR 13-Speed Drivetrain With Power Meter

This premium build is equipped with the SRAM RED XPLR AXS 13-speed drivetrain, delivering precise wireless shifting and an expanded gear range thanks to the 10–46t cassette. The integrated power meter chainring gives you accurate training data, while updated lever ergonomics and highly refined hydraulic brakes reduce hand fatigue and braking effort, keeping you fresh and in control deep into hard efforts.

Roval Terra CLX II Wheels for Speed and Stability

The Roval Terra CLX II carbon wheels strike an ideal balance between low weight, durability, and compliance. They accelerate quickly, maintain speed over rough surfaces, and provide confident handling when descending fast gravel roads or navigating technical sections.

Premium Touch Points for Comfort and Control

An S-Works Power Saddle with Mirror technology reduces pressure and improves support during long rides, while the Roval Terra carbon handlebars and Roval Alpinist carbon seatpost enhance comfort without sacrificing responsiveness. These details ensure the Crux remains comfortable and controllable even during long, high-intensity gravel events.

If you want the lightest gravel bike in the world combined with elite-level components, race-ready geometry, and massive versatility, the Specialized S-Works Crux is unmatched. It’s built for riders who want to go faster everywhere, climb easier, and push harder across gravel, dirt, and beyond, with no compromises holding them back.
