Specialized S-Works Epic WC 2025

Think fastest

The Epic World Cup is the fastest XC race bike in the world on smooth to moderately technical courses thanks to its unmatched combination of efficiency, control, and light-weight. World Champ Christopher Blevins said it best, “This thing gives me everything I could want from a hardtail, plus the control and capability of full suspension.” All it took to create this speed machine was a totally integrated development approach, inventing a radical new shock, and four decades of off-road winning experience.

FRAME OF REFERENCE
To deliver maximum speed through ruthlessly efficient power transfer and precision handling, engineering team set and achieved new standards in torsional rigidity and BB stiffness. This feat required an integrated development approach that merged a structurally superior double diamond layout with its shock cradled inside the top-tube, and finished off with the most sophisticated composite layup in Specialized history.

SHOCKINGLY FAST
The Specialized Ride Dynamics team conceived of and invented a revolutionary shock technology for the Epic World Cup that gives the rider the efficiency and snappy response of a hardtail PLUS the control, capability, and momentum-carrying of full suspension—all with a simple setup. Co-developed with RockShox, the SID Deluxe WCID shock utilizes a unique independently adjustable positive and negative air springs to deliver the sought-after hardtail “snap”, combined with terrain-devouring forgiveness, and the ability to easily personalize set-up for a specific course or tune for rider preference and feel. Set it firm and it rides like a hardtail or open it up and you have a chunk-squashing ripper. But you aren't just limited “open and closed,” the simple nature of its setup allows the rider to set on a spectrum of firm to soft.

PUNCHING ABOVE ITS CATEGORY
The Epic World Cup’s 75mm of rear travel delivers control and capability of a much longer travel bike. Because it’s designed to be ridden at or close to topped-out, it yields the same positive travel as a 100mm travel bike set up with 25% sag. To further optimize suspension performance, the Specialized Ride Dynamics team tuned the spring-rate to be relatively flat through the mid-stroke to handle the majority of bump forces like a longer travel bike. Due to its large size, the custom Mega Jounce Bumper is an “industry first” and plays a crucial role in smoothly managing bottom-out on the biggest impacts.

HAVE WE LOST OUR MINDS?
The groundbreaking SIDLuxe WCID shock provides a unique blend of support and compliance in the rear, while the RockShox SID SL with 3-Position Race Day 2 damper borrows the all-new Epic 8s “Magic Middle” tune, providing support under pedaling and 110mm of bump-muting, active suspension in the rough to provide ultimate efficiency.

THE WEIGHT IS OVER
With a frame weight of just 1,765 grams (painted with shock and all hardware), the Epic World Cup edges out the lightest of competitors. This translates to faster acceleration, more efficiently climbing, and more agile handling. And all of that adds up to speed. We achieved the featherweight and monster stiffness of the Epic WC by applying what we learned in the development of our Aethos, the lightest production road frame ever made, specifically the advanced composite layup and tube shapes.

THE BIGGEST FLEX IS NO FLEX
The Epic World Cup sports the full suite of Roval Control SL components: 1,240-gram wheelset, 180-gram seat post, and 250-gram integrated cockpit (70mm x 780mm). Each boasting peerless light-weight, stiffness, and control on the World Cup today.

Features

• The all-new Epic World Cup frame features Ride Dynamics Developed suspension technology and 75mm of optimized rear wheel travel. Thanks to its shock technology, Epic World Cup delivers unmatched pedal efficiency and is ready for the roughest descents you can throw at it–no lockout switches required.
• SRAM XX SL transmission builds on what top riders need in shifting performance and robustness, making it perfectly matched for the brutal demands of off-road racing.
• A RockShox SID SL with 3-Position Race Day 2 damper provides support under pedaling and 110mm of active suspension to provide ultimate efficiency.
• Created specifically to match the increased capabilities of the Epic World Cup, the Roval Control SL rim introduces a completely new offset rim profile that features a 29mm internal width that not only increases strength and reduces weight, but also improves pinch-flat resistance by 22-percent.
