Specialized Stumpjumper Comp Carbon 27.5" Mountain Bike 2019
Lightweight, fast and highly-durable, the new Stumpjumper Comp Carbon 27.5" Mountain Bike is Specialized’s solution to the do-it-all trail weapon. Offering 150mm of plush front and rear travel, it strikes the perfect balance between climbing efficiency and downhill stability, while the 27.5” wheels rail tight corners with ease.
Combining Fox’s highly-regarded Float Rhythm 34 Fork with their matching Float DPS shock, the Stumpjumper provides a smile-inducing ride, popping off jumps and dominating technical descents with style. Perfected with an X-Fusion Manic seatpost, this bikes versatility is further enhanced, allowing you to seamlessly transition between climbing and descending at the push of a lever.
Shimano components make up the drivetrain and brakes, with an SLX and XT blend offering the smooth, reliable shifting expected from an 11-speed setup. The matching SLX hydraulic disc brakes are another key feature, boasting fantastic modulation and biting power, so you can tackle the steepest of gradients with confidence.
Completed with 29mm wide hookless Roval Traverse Wheels and Specialized’s own brand 2.6” wide tyres, the Stumpjumper provides near limitless grip through even the most extreme of weather conditions, perfect for those looking to explore the trails through all four seasons.
