PRODUCT DETAILS
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. 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.
01

9:58 Faster Over Unbound

So what happens when we run the Equation of Speed with:

15.2 watts less aerodynamic drag
A 789 gram frame (56cm S-Works)
6.9 kg system weight
Hyper-accurate surface telemetry
Elite rider power profiles
9:58 saved.

Racing the 2025 Unbound on a 2026 Crux 5 would save Sofía Gómez Villafañe over 9:58—purely through equipment efficiency.

This level of simulation may be unique in cycling, but not in other elite sport. Both Formula 1 and America’s Cup sailing utilize simulation extensively to benchmark and refine performance. Hyper-accurate simulation has been one of the key reasons both of these sports have seen such massive leaps in performance.
02

A System of Speed

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

Aero Gains Breakdown:

Frame, fork & seatpost: 50%
Roval Terra Aero wheels: 30%
Roval Terra cockpit: 20%
*15.2 watts as spec’d with our Moving Leg Mannequin at 45 kph. Results may vary up or down depending on individual riders.

The Science Club at our Morgan Hill Innovation Center built mules—preliminary test prototypes that bonded parts of the Crux 4 with parts of the Tarmac SL8. From a Crux 4 with a Tarmac SL8 seat tube and seat post, to a full Tarmac SL8 rear end bonded to a Crux front triangle with a custom aero fork, the Science Club began to hybridize road-level aero gains with gravel-light weight savings.

All those aero gains were validated with the Moving Leg Mannequin, because being fast without a rider is meaningless.
03

Rider Inclusive Aerodynamics

No gravel bike is raced without a rider—and no aero data is meaningful without one either. That’s why our Win Tunnel testing incorporates our Moving Leg Mannequin, now in its sixth generation. Unlike static mannequins or bike-only testing, this system captures how a rider’s full body in motion alters airflow across the bike at race-relevant speeds.

The new sixth generation Moving Leg Mannequin delivers:

Increased repeatability
Reduced test-to-test variance
More accurate rider-inclusive CdA values
A rider’s legs in motion dramatically change the airflow. Any aero calculations that omit this key factor are incomplete.
