Specialized Stumpjumper Comp Mountain Bike
With an all-new design, the Specialized Stumpjumper Comp Mountain Bike offers excellent handling and trail performance in a stout, full-carbon, 130mm travel package. Building a bike to excel on all trails is no mean feat, but this latest revision sees the Stumpjumper truly deserving its title of the ultimate trail bike. Similar visuals belie the host of behind the scenes changes, with revamped suspension and thoughtful geometry adjustments leading to an uber-capable trail-bike designed to elevate your riding.
Hitting the sweet-spot for trail riding, revised geometry sees roomy and confidence-inspiring reach measurements throughout the sizes. Rider-First Engineered™ sizing allows you to pick the bike for your riding style, not your height. Looking for a more stable ride? Size up for the stability benefits that a longer wheelbase provides, or size down for improved manoeuvrability on tight trails - with low seat tube heights across the size range, the choice is in your hands. A geometry-adjust flip-chip allows for half a degree of head angle adjustment, swappable at the trailside with only an Allen key required.
The 130mm of rear suspension travel on offer works hard, so you do not have to. A progressive leverage curve prevents harsh bottom outs, providing support for a lively on-trail feel. Climbing characteristics have been improved, with revised suspension kinematics and steep seat-tube angles providing an incredible platform for even the steepest climbs. Long, low and slack, the Stumpjumper Comp is more than up for the descents. Blow out turns and boost off trail features, the bikes poppy nature looks to add new life to your riding.
The Shimano SLX 12-speed drivetrain was the natural choice for the Comp, providing crisp, lightweight performance without blowing the budget. FOX suspension front and rear offers ample grip and adjustability, allowing you to fine-tune your setup to your local trails. SWAT™ storage makes a welcome return, complete with increased space for your tools, nutrition and more, for all trailside eventualities. 29" tubeless-ready Roval hoops keep the Stumpjumper Comp rolling fast over bumps and ruts, offering high top-speeds and predictable cornering.
