Crux 5 S-Level - SRAM RED XPLR

Specialized Crux 5 S-Level - SRAM RED XPLR

Eat My Dust

The Specialized Crux 5 S-Level - SRAM RED XPLR was born from 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

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.

*Time savings for Sofía Gómez Villafañe vs. Crux 4, assuming same course, conditions, and rider input as 2025 Unbound

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.
