ONE ATLAS, MANY WAYS TO LOSE YOURSELF

Dedicated to race, the newest Crux reclaims its position at the head of the pack. The all-new 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 across real race courses, real terrain and real riders. When the goal is the top step, nothing in gravel gets you there faster.

Time to Finish

When the objective is winning races, the goal is brutally simple. Get riders to the finish line faster. For Crux 5, that meant answering one question. Does this bike reduce total race time on the fastest, hardest gravel courses on Earth? To answer that, Specialized built the most comprehensive gravel race simulations ever created. The result? Crux 5 is up to 9:58* faster over Unbound than Crux 4.

Specialized Most Aerodynamic

The Crux 5 is the most aerodynamic gravel race bike Specialized ever made. Drawing directly from Tarmac SL8 learnings and decades of aero research, every tube on Crux 5 was sculpted for speed at elite gravel race speeds. Resulting in a 15.2 watts faster bike.

Nothing is Lighter

At 789 grams, the S-Works Crux 5 frame stands alone at the top of the gravel lightweight category. Complete builds start at 6.9 kg—a number most road bikes envy. Even in a full aero setup with 55 mm clearance and Tera Aero CLX III wheels, S-Works Crux 5 is lighter than the competition at 7.1 kg. This was made possible by Flow State Design, first pioneered on the Aethos road bike.

Unparalleled Ride Quality

Speed isn’t just about peak numbers - it’s about sustaining power and pace deep into the race. Crux 5 delivers telepathic handling, instantaneous acceleration, and balanced compliance that reduces fatigue on the roughest courses. Rider-First Engineered and now with 55 mm tyre clearance for unmatched traction and comfort, it preserves the legendary ride feel of Crux 4 and adds real aerodynamic performance.
