S-Works Epic World Cup - SRAM XX SL AXS, RockShox Ultimate
Speed built for the dirt
THINK FASTEST: The S-Works Epic World Cup is the fastest XC race bike in the world on smooth to moderately technical courses, thanks to an unmatched combination of efficiency, control, and light weight. World Champion Christopher Blevins put it best: “This thing gives me everything I could want from a hardtail, plus the control and capability of full suspension.
Best for: Cross-country racing, fast trail riding and efficient climbing.

Key highlights
A 1,765-gram frame (painted, with shock and hardware) built around Specialized’s WCID suspension design, merging hardtail snap with full-suspension control.
A wireless, direct-mount 12-speed drivetrain with a 10-52t cassette and a Quarq XX SL power meter crankset, built for the brutal demands of World Cup racing.
110mm of Position-Sensitive travel that firms up under power and opens up over rough terrain — no remote lockout required.
A 1,240-gram carbon wheelset with a 29mm internal width, paired with S-Works Fast Trak and Renegade tyres for low rolling resistance and confident cornering grip.
