Specialized S-Works Crux 5 (SRAM Red XPLR) Gravel Bike 2027

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 racecourses, real terrain, and real riders. When the goal is the top step, nothing in gravel gets you there faster.

Time to Finish

The Only Metric that Matters

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, we built the most comprehensive gravel race simulations ever created. The result? Crux 5 is up to 9:58* faster over Unbound than Crux 4.

Our Most Aerodynamic

15.2 Watts Faster**

The Crux 5 is the most aerodynamic gravel race bike we’ve 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.

Nothing is Lighter

Flow State Design Delivers a 789 Gram Frame

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 Terra 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 Everywhere, All-Day

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 tire clearance for unmatched traction and comfort, it preserves the legendary ride feel of Crux 4 and adds real aerodynamic performance.
