The S-Works Crux 5 is a gravel racing frameset built around FACT 12r carbon construction. Weighing just 789 grams, the frame pairs with an S-Works FACT Carbon fork to keep overall frameset weight at 1.63 kg. A threaded bottom bracket shell and UDH dropout provide broad drivetrain compatibility across a range of gravel race builds.
The frameset runs a 12x142mm rear thru-axle and flat-mount disc interface, with the fork matching via a 12x100mm thru-axle. The included S-Works Tarmac SL8 carbon seatpost offers a 15mm offset and lightweight saddle clamp, while an integrated wedge seat binder keeps the cockpit tidy and reduces external hardware at the seat tube.
