No matter how much we love our Epic FSR, it's undeniable that hardtails still play an extremely important role in XC racing. So what to do? We put our XC offerings on a diet, went back to the drawing board, and created the lightest damn mountain bike we've ever made—the S-Works Epic Hardtail. To do so, we built the entire frame from our highest-end carbon fiber, FACT 12m, and then we took some cues from our road bikes. We borrowed the Rider-First Engineered™ concept that originated with the Tarmac. Now, the frame design applies specificity to every tube size and carbon layup for every frame size. This creates the optimal balance of rigidity, weight, and responsiveness, so every frame, regardless of size, performs just as we intended. We've also tweaked the geometry for more speed and stability by slacking-out the head tube angle, lengthening the top tube, and correcting the seat tube angle. This way, it feels more planted then ever, and frankly, it's stupid fast. We also widened the rear spacing to 12x148mm and included internal split-housing cable routing. For the build, the S-Works spares no expense, opting for a RockShox SID World Cup w/ Brain fork, Shimano XTR Di2, and hand-built Roval Control SL carbon wheels.
  • To provide the optimal blend of stiffness, crazy light weight, and strength, we constructed the frame from our FACT 12m carbon fiber. And when combined with our XC 29 Geometry, the Epic is guaranteed to deliver uncompromising, blistering speed and agile handling come race day—no matter the course.
  • The RockShox SID World Cup 29 w/ Brain fork provides 90/100mm of efficient travel. It features Brain technology that distinguishes between terrain and rider input in order to maximize your power, while a Brain Fade adjusts the oil flow when not hitting bumps.
  • Drivetrain duties are handled by the revolutionary Shimano XTR Di2 11-speed groupset, with 36/26T gearing up front and 11-40t at the rear. The first ever electronic mountain groupset, it provides unparalleled shift precision, reliability, and accuracy, making it the secret weapon in any racer's arsenal.
