Product Details

Competitive XC Hardtail DESIGNED TO FLY With a FACT carbon or M5® alloy frame, the Stumpjumper® is designed to fly with unbeatable efficiency, super low weight and precision handling that'll guide you through even the stickiest of situations. Inside Tech TECH We've been continually refining the Stumpjumper for over two decades, and by now, we've tweaked and tuned the frame materials we use to the point of near perfection (yet, as great as they are, we're always pushing to make them better.) Today's FACT carbon or M5 alloy hardtails both feature completely proprietary frame materials that have been developed by our engineers for unparalleled efficiency, low weight and precision handling.
