Crux 5 Expert

Eat My Dust

The Crux 5 was born from the fastest gravel race bike ever made. Not just because it’s the lightest. Not just because it’s our most aero. Not just because it handles dirt like a Tarmac handles pavement. But because it delivers the lowest real-world Time to Finish of any gravel bike ever made. Crux 5 turns more of your effort into pure speed—validated for real race courses, real terrain, and real riders. When the goal is the top step, nothing in gravel gets you there faster.

Technical Specifications

The Crux 5 Expert is built around a Crux 5 FACT 10r Carbon frame featuring Rider First Engineered™ technology. The frame includes a threaded BB, a 12x142mm thru-axle, flat-mount disc compatibility, and a UDH dropout. Up front, the bike is paired with an S-Works FACT Carbon fork featuring a 12x100mm thru-axle and flat-mount disc design.

Braking performance comes from SRAM Force E1 hydraulic disc brakes at both the front and rear, delivering confident stopping power and control across every ride.

The drivetrain features SRAM Force AXS E1 hydraulic disc shift levers paired with a SRAM Force AXS E1 XPLR 13-speed rear derailleur. Power is transferred through a SRAM Force E1 XPLR 13-speed 10-46t cassette and SRAM Force Flattop E1 chain, while the SRAM Force E1 XPLR DUB Wide crankset is fitted with a 40t chainring. Completing the drivetrain is a SRAM DUB BSA 68 Wide bottom bracket.

The wheelset consists of Roval Terra C III carbon wheels with 27mm inner width carbon rims, a tubeless-ready design, and a 25.5mm rim depth. Both the front and rear wheels are built with DT 370 hubs, 24 spokes, and Sapim D-Light spokes. The wheels are fitted with Pathfinder 700x45 Tubeless Ready tires and paired with 700x32–50mm inner tubes featuring 40mm Presta valves.

The cockpit is equipped with a Roval Rapide alloy stem featuring a four-bolt design and a -6-degree angle, complemented by Roval Terra carbon handlebars with a 103mm drop, 70mm reach, and 12º flare. Supacaz Super Sticky Kush bar tape provides a secure grip, while the Body Geometry Power Expert saddle with hollow titanium rails enhances rider comfort.
