Crux 5 Sport Shimano GRX RD-RX822-GS 12s DT Swiss G500 rim

Specialized Crux 5 Sport is built for riders who see gravel racing through one clear metric: time to the finish. Developed from the fastest gravel race bike Specialized has ever created, it combines low weight, aerodynamic efficiency and confident off-road control for competition. The 897 g FACT 10r carbon frame works with the S-Works FACT Carbon fork to deliver a responsive and stable ride when the course turns rough, technical or very fast.

Crux 5 Sport is designed to convert rider power into real speed. Tube shapes inspired by the aerodynamic knowledge behind the Tarmac SL8 help reduce drag, while Rider First Engineered construction keeps handling and performance consistent across sizes from 49 to 61 cm. The result is a race gravel bike that can hold momentum, comfort and control into the final part of the race.

The mechanical Shimano GRX 12-speed drivetrain delivers dependable shifting and race-ready gearing, with a 40-tooth chainring and 10-45t cassette for climbs, attacks and fast rolling sectors. Shimano GRX BR-RX820 brakes provide confident stopping power in changing conditions, while DT Swiss G500 wheels, with a 26 mm internal width and tubeless-ready construction, pair with Pathfinder 700x45 Tubeless Ready tires to balance speed, grip and comfort on demanding gravel.

Cockpit combines a Roval Rapide alloy stem, Specialized Adventure Gear handlebar with 12-degree flare, Supacaz Super Sticky Kush bar tape and a Body Geometry Power Sport saddle, giving the bike control and efficiency during hard efforts and long days. The S-Works Tarmac SL8 Carbon seatpost helps reduce fatigue while preserving the direct, lively ride quality that made the Crux platform so respected.

With a stated weight of 8.94 kg, Specialized Crux 5 Sport is a light aero gravel racing bike ready for fast courses, rough surfaces, long events and rides where speed matters most. It is built to help you arrive sooner, with the handling, traction and efficiency needed when every second counts.
