No-nonsense, unadulterated XC speed—that's what Specialized's S-Works Stumpjumper 29 brings to the dirt. Its heart is a feathery S-Works FACT-carbon frame, which absolutely flies uphill and boasts race-proven geometry for the trip back down, while the rear features a hardtail design with razor thin seatstays that blend maximum pedaling efficiency with added compliance. Enhancing the incredible frame is Brain-controlled, 95mm-travel RockShox RS-1 fork that sports an inverted design and offers superior stiffness, while behaving with more sensitivity to small bumps and more control over larger hits. Drivetrain duties are handled by the revolutionary Shimano XTR Di2 11-speed groupset, the first ever electronic mountain groupset, which provides unparalleled shift precision, reliability, and accuracy, making it the secret weapon in any racer's arsenal. Featherweight Roval carbon wheels make you feel like you're cheating, and wonderfully light, powerful Shimano XTR disc brakes have modulation to spare. Not stopping there, you get a world-class S-Works carbon seatpost, a carbon-railed Phenom saddle and tubeless S-Works Fast Trak tires. Is this one of the fastest bikes on Earth? Specialized Factory riders think so, and they back it up with endless podium spots.
