S-Works Crux 5

Eat My Dust

The S-Works Crux 5 is 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 S-Works Crux 5 is built around an S-Works Crux 5 FACT 12r 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 RED E1 hydraulic disc brakes at both the front and rear, delivering exceptional stopping power and precise control.

The drivetrain features SRAM RED AXS E1 hydraulic disc shift levers paired with a SRAM RED AXS XPLR E1 13-speed rear derailleur. Power is transferred through a SRAM RED XPLR E1 13-speed 10-46t cassette and SRAM RED E1 chain, while the SRAM RED XPLR E1 crankset with a Quarq power meter is fitted with a 40t chainring. Completing the drivetrain is a Ceramic Speed BB Alpha BSA DUB bottom bracket.

The wheelset consists of Roval Terra Aero CLX carbon wheels with a tubeless-ready design and 27mm internal width carbon rims. The front wheel features a 50mm rim depth, an 18-hole Roval LF18-F hub with ceramic SINC bearings, Centerlock disc compatibility, and Roval by ARRIS Composite Aero Spokes with titanium end pieces. The rear wheel features a 45mm rim depth, a 24-hole Roval LF19-R hub with ceramic SINC bearings, Centerlock disc compatibility, and Roval by ARRIS Composite Aero Spokes with titanium end pieces. Both wheels are fitted with Pathfinder 700x45 Tubeless Ready tires and paired with 700x32–50mm inner tubes featuring 60mm Presta valves.

The cockpit is equipped with the integrated Roval Terra Cockpit bar and stem combination, finished with Supacaz Super Sticky Kush bar tape. Rider comfort is enhanced by the S-Works Power with Mirror saddle, supported by an S-Works Tarmac SL8 FACT Carbon seatpost with a 15mm offset and Lightweight Saddle Clamp, and secured by an Integrated Wedge seat binder.

The product carries Product ID 294828 and has a complete weight of 7.1 kg (15 lb, 10.4 oz) in a size 56.
