Think of the Ultralight edition of the Epic Hardtail as a science experiment—a lesson in just how crazy light and capable you could make a race bike. We pulled out all the stops on this one and the end result is your personal rocket ship to the top step of the winner’s podium.
- At 775 grams, the new S-Works Epic Hardtail chassis is the lightest production hardtail frame on earth. What’s more, we’ve designed it to be incredibly capable and comfortable, with progressive geometry and an advanced composite layup that boosts vertical compliance.
- A Fox Factory Step-Cast 32 shaves the grams while providing 100 millimeters of silky, Kashima-coated suspension. And since weight is the enemy here, we equipped the Ultralight with some equally ultralight Roval Control SL carbon wheels. SRAM’s XX1 Eagle drivetrain gives you massive gear range and quick, precise shifts. Finally, the Ultralight can go from crazy-quick to a tidy stop, thanks to the trademark modulation and power of Magura’s MT8 SL disc brakes.
