The Crux 5 Comp is a gravel race bike that puts proven race frame geometry and wireless shifting at the most accessible point in the lineup. The FACT 10r carbon frame weighs 897 grams, and a size 56 build comes in at 8.89 kg (19 lb, 9.6 oz). Rider First Engineered construction matches the layup to each frame size, while a threaded BB, 12x142mm rear thru-axle, flat-mount disc interface, and UDH dropout keep maintenance and parts swaps simple. An S-Works FACT carbon fork runs a 12x100mm thru-axle up front.
Shifting comes from SRAM Rival AXS XPLR E1, a 13-speed wireless group paired to a 10-46t cassette and a 40t crankset for the climbing range gravel days require. SRAM Rival E1 hydraulic disc brakes stop front and rear. DT Swiss G500 rims have a 26mm internal width and tubeless-ready bead, 24h front and rear on Specialized sealed-bearing hubs with DT Swiss Champion stainless spokes and brass nipples. Pathfinder 700x45 tubeless-ready tires grip across loose gravel and hardpack.
The cockpit pairs a Specialized Adventure Gear alloy handlebar, set with 118.9mm of drop, 70mm of reach, and 12 degrees of flare, to a Roval Rapide alloy stem at -6 degrees. A Body Geometry Power Sport saddle on steel rails and Supacaz Super Sticky Kush tape finishes the contact points, with an S-Works Tarmac SL8 carbon seat post at 15mm offset on an integrated wedge binder. For the rider entering gravel racing on a durable build, the Crux 5 Comp offers the gearing and stability to stay in the pack over long courses.
