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.
Meet the Crux 5, the fastest gravel race bike Specialized has ever built. It wasn't designed around one single breakthrough, but around the only number that actually matters on race day: Time to Finish. Every decision, from the aerodynamic shaping borrowed from the Tarmac SL8 and validated in the Win Tunnel, to the 789g FACT 12r frame* that keeps complete builds starting at just 6.9kg, was made with one outcome in mind: getting you to the line first. The result is a bike that's 15.2 watts faster at race speeds, with race-tuned geometry and 55mm of tire clearance that keeps you riding strong and in control long after others start to fade. In real race conditions over a course like Unbound, that adds up to nearly 10 minutes. For anyone who lines up to win, the Crux 5 is the only bike worth racing.
