Description
Specialized Stumpjumper Comp Alloy 29" Mountain Bike 2018
Reinventing the trail bike was never going to be an easy task, yet Specialized defied the odds with their latest Stumpjumper. Utilising a longer and slacker geometry than its predecessor, the Stumpjumper 29" Comp Alloy is a mountain bike like no other.
Offering exceptional performance both up and downhill, this playful machine provides the ultimate solution to single bike simplicity. Combining 140mm of plush rear wheel travel with Fox’s highly-regarded Rhythm 34 Fork, this versatile bike absorbs big hits and trail chatter with equal efficiency, while the boost spacing promotes stiffness on challenging terrain.
Shimano's SLX gearing provides the slick shifting expected from an 11-speed offering, while the matching hydraulic disc brakes ensure confidence-inspiring stopping power all year round.
The Roval Traverse Wheelset further enhances performance. Featuring a 29mm internal rim width and sealed bearings, these premium wheels promote smooth rolling and stability, no matter the gradient ahead. Similarly, the 2.6” wide Specialized tyres offer phenomenal grip in both the wet and dry, while an X-Fusion Manic dropper seatpost ensures a seamless shift between climbing and descending.
FEATURES
- Shimano SLX hydraulic disc brakes
- Shimano SLX 11-speed drivetrain
