At the pinnacle of the XC game resides Specialized's S-Works Stumpjumper 29er. Its heart is a feathery S-Works FACT-carbon frame, which absolutely flies uphill and boasts race-proven geometry for the trip back down. Up front, RockShox's 90mm RS-1 fork with BrainFade dismantles techy trails for premium control and efficiency. And this rig is spec'd with the best of the best. We're talking full XTR 2 x 10-speed gearing, feathery carbon components, Roval SL carbon wheels, and Magura carbon brakes for supreme control in all weather and trail conditions. Plus, you also get Specialized's Command Post XCP dropper seatpost for 35mm of wiggle room when the descents get extra steep. Is this one of the fastest bikes on Earth? Specialized Factory riders think so, and they back it up with podium spots. A lot.
