Specialized Crux 5 Frameset

$7,499.99

The S-Works Crux 5 is the fastest gravel frame set 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.

Specialized Crux 5 Frameset

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.

*S-Works frame only

Sizing Guide

The sizing chart is a great place to start when picking your next bike but everyone will fit a bike a bit differently. Your torso, arm, and leg lengths all play into what size of bike you may need. Plus, there's your own personal preference.

We always recommend swinging by the shop and taking the bike that you're looking for a spin to see how it feels. If you're unable to come by, looking at the geometry of your current bike and comparing it is a good place to start. If you have any further questions, our customer service team is there to help.
