The Specialized Stumpjumper 15 Full Suspension Mountain Bike is designed to eliminate all trade-offs on the trail. This trail-demon smooths out bumps like a heavy-duty bike, gives you the control, playfulness, and efficiency of a short-travel bike, and offers the ultimate customisation tailored just for you.
Breakthrough Capability: GENIE Shock Technology combines a lively, playful ride with a bottomless downhill feel.
Ultimate control: Provides significantly better traction than the award-winning Stumpjumper EVO.
Unmatched personalisation: Features include six-way geometry adjustment, a choice of mixed or 29” wheels, a tunable spring curve, and more.
Genie - The Magic Carpet Ride: The standout innovation on the Stumpjumper 15 is GENIE, Specialized's patent-pending air spring technology. It delivers the coil spring’s feel and control, superior bottom-out prevention, and a tunable platform for a playful ride.
Illuminating Genie: GENIE offers the control of a coil spring during bumps and the progressive spring rate of an air spring at the end of the stroke to prevent bottom-outs. This blend provides extra tunability, merging the best of coil and air springs.
With 16.3% better bump force management than a traditional air shock, GENIE makes the Stumpy 15 perform like a bike with more travel. For instance, both the Stumpjumper 15 (145 mm rear travel) and the Enduro (170 mm travel) use 101 mm of travel to absorb a 1080 N bump force.
Traction Galore: Extensive field testing shows that the Stumpjumper 15 with GENIE offers 57% better traction than a standard air shock. GENIE technology ensures a supple, coil-like performance, maintaining wheel contact with the ground more effectively.
Experience 39% fewer bottom-outs compared to a standard air spring. The pronounced rising rate in the last 30% of the GENIE stroke reduces the frequency and severity of bottom-outs during big hits.
This bike’s geometry offers the capability of a big bike, agility in tight sections, and efficient climbing. The spacious cockpit centres you on the bike, optimising traction and corner control, while the low bottom bracket, slack head tube angle, and optimised fork offset ensure stability in rough terrain.
The Stumpjumper 15 features benchmark geo adjustability, making it the most customisable trail bike ever. Six distinct geometry settings allow you to fine-tune performance for any style and terrain. Adjust the head angle and bottom bracket height for stability or clearance.
With Specialized's aftermarket shock links, choose between 29” wheels front and rear or a mixed setup with a 27.5” rear for a more responsive and playful ride, with no impact on geometry.
The SWAT 4.0 on the Stumpjumper 15 enhances downtube storage, offering a smooth, weather-resistant, flush-mounted system.
