Specialized S-Works Crux 5 2027 - SRAM RED XPLR
The Specialized S-Works Crux 5 is a no-compromise gravel race bike designed to turn rider effort into speed across real courses and changing terrain. Its 789g FACT 12r carbon frame is paired with SRAM RED XPLR, a Quarq power meter, Roval Terra Aero CLX wheels and an integrated Roval cockpit. At a claimed 7.1kg in size 56, it combines exceptionally low weight with aerodynamic efficiency and precise handling.
A 789g FACT 12r Carbon Frame
At a claimed 789g, the S-Works Crux 5 frame keeps weight exceptionally low without losing the stiffness and control required for gravel racing. Reduced frame weight makes the bike easier to accelerate, carry through steep run-ups and drive over repeated climbs.
FACT 12r carbon construction allows Specialized to tune each area according to its structural purpose, placing stiffness where it improves power transfer while retaining the control needed on rough surfaces.
Designed for Real Gravel Speed
The Crux 5 has been developed to reduce finishing times across real gravel courses rather than focusing on weight or aerodynamics in isolation. Its design balances low weight, aerodynamic efficiency and confident handling across changing terrain.
This approach helps the bike remain efficient on exposed roads and high-speed sections while retaining the accuracy needed for loose corners, technical descents and uneven surfaces.
SRAM RED XPLR 13-Speed
SRAM RED AXS XPLR provides precise wireless electronic shifting through a gravel-specific 1x13-speed drivetrain. The 10–46T cassette offers closely spaced gearing for maintaining cadence while retaining the range needed for steep gravel climbs.
The full-mount rear derailleur attaches around the rear axle rather than using a conventional derailleur hanger. This creates a robust system designed for demanding off-road use and consistent shifting under load.
Quarq Power Measurement
The SRAM RED XPLR crankset includes a Quarq power meter for measuring rider output. Accurate power data helps riders pace long races, structure training and avoid using too much energy during the early stages of an event.
A 40-tooth chainring provides a useful balance between climbing range and speed when paired with the 10–46T cassette.
Roval Terra Aero CLX Wheels
Roval Terra Aero CLX wheels combine deep carbon rims with composite aerodynamic spokes and ceramic hub bearings. The 50mm front and 45mm rear rim depths are designed to reduce aerodynamic drag while remaining suitable for fast gravel racing.
A 27mm internal rim width supports the 45c Pathfinder tyres effectively, improving tyre stability when cornering or riding at lower pressures. Tubeless-ready construction also allows improved puncture protection once converted with suitable valves and sealant.
Integrated Roval Terra Cockpit
The Roval Terra integrated handlebar and stem provide a clean, race-focused front end while reducing the number of separate components. Its carbon construction helps keep weight low and gives the bike precise steering response.
The S-Works Tarmac SL8 carbon seatpost and S-Works Power Mirror saddle complete a premium contact-point package designed for performance and support during long races.

Our Thoughts on the Specialized S-Works Crux 5
The Specialized S-Works Crux 5 is built for riders whose priority is race performance. Its 789g FACT 12r frame creates an exceptionally light foundation, but the bike’s appeal goes beyond its weight. Aerodynamic wheels, precise handling and a fully integrated component package make it suitable for complete gravel courses rather than only performing well on climbs.
The SRAM RED XPLR drivetrain is an ideal match for this frame. Its 13-speed cassette provides useful gear progression and gravel-ready range, while the Quarq power meter makes the bike ready for structured training and accurate race pacing. Roval Terra Aero CLX wheels add a meaningful aerodynamic advantage while retaining the width needed for 45c tyres.
For riders seeking a complete gravel race bike with no obvious component compromises, the S-Works Crux 5 represents the highest-performance option in the Crux range.
