Specialized S-Works Epic 8 Bike (2025)

Specialized S-Works Epic 8 Mountain Bike 2025 Season in Red. Specialized Reference: 90326-0104

The new Epic 8 evolves the formula for ultimate speed with its capability, efficiency, and lightweight integration. Modern XC trails demand more capability every day. Discover the Epic 8. Its improved kinematics make it the most efficient pedaling bike we've ever tested, while custom-valved (and tuned) shocks absorb every bump. It's a true beast.

If you're an XC racer or prioritize top-end speed on your rides, the Epic 8 is the bike for you.

UNRIVALED CAPABILITY: The most capable 120mm bike on the planet. You'll be amazed at how the Epic 8's progressive geometry delivers capability on technical terrain alongside quick, efficient climbing and acceleration performance. The incredible lateral and torsional rigidity of the chassis also translates to highly precise handling.

WHAT'S THE DRIVE?: Compared to the previous generation, the new Epic 8 absorbs 12% more impacts and vibrations, leaving you less fatigued and with more power so you can keep pedaling even when they're suffering.

TUNED RIDING DYNAMICS: The Specialized Ride Dynamics team developed custom valving for the Epic 8's new shock. Our unique damping characteristics, prescribed by Ride Dynamics, enhance the ride experience. By tuning the shocks along with the chassis' leverage ratios and new kinematics, we're able to deliver a bike that's greater than the sum of its components.

BIOMECHANICAL EFFICIENCY: By optimizing the suspension kinematics, the Specialized Ride Dynamics team reduced inefficient pedal-induced roll by 20%, keeping the suspension active for effective impact force management and ensuring a more efficient pedaling position. It's the most pedal-efficient suspension bike we've ever tested.

MORE WITH LESS: With the Epic 8, we didn't spend an extra gram to get incredible frame capability. All models now feature SWAT 4.0 to carry all your trail essentials and an integrated headset stop to prevent the typical top tube scarring from the first drop and handlebar slippage. In fact, the new S-Works Epic 8 frame has even reduced its weight (76 grams, to be exact) by incorporating these new features.

ROCKSHOX FLIGHT ATTENDANT: Free your mind to focus on speed at the crucial moment. RockShox Flight Attendant (on S-Works models) optimized with Specialized Ride Dynamics leverages SRAM AXS wireless technology to gather real-time data from you and the terrain and determine the optimal compression settings for an unparalleled rider experience.
