The Specialized Stumpjumper 15 Full Suspension Mountain Bike is designed to eliminate every compromise on the trail. It tackles bumps like a big bike, delivers short-travel control, playfulness, and efficiency and offers customisation to suit you perfectly.
BREAKTHROUGH CAPABILITY: GENIE Shock Technology combines a lively, playful ride with a bottomless downhill feel.
ULTIMATE CONTROL: Offers significantly better traction than the "Bike of the Year" Stumpjumper EVO.
Experience unmatched personalisation from a six-way geometry adjustment, mixed wheel or 29” options, and a tunable spring curve.
GENIE - The Magic Carpet Ride: The standout innovation on the Stumpjumper 15 is GENIE. This patent-pending air spring technology offers the feel and control of a coil spring, superior bottom-out prevention, and a tunable platform for a playful ride.
GENIE combines the linear spring rate of a coil spring in the “bump zone” with the progressive spring rate of an air spring at the end of the stroke to prevent bottom-outs. This offers the best of both worlds, coil and air, with extra tunability. Say goodbye to compromises and hello to the future of riding.
With 16.3% better bump force management than a traditional air-sprung shock, GENIE makes the Stumpjumper 15 ride 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.
Extensive field testing shows that the Stumpjumper 15 with GENIE provides 57% better traction than a standard air-sprung shock. GENIE technology ensures a supple, coil-like performance, keeping the wheel in 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 big bike capabilities when needed, agility in tight sections, and efficient climbing. The spacious cockpit centres you on the bike, optimising traction and cornering. A low bottom bracket, slack head tube angle, and optimised fork offset ensure stability in rough terrain.
The Stumpjumper 15 features exceptional geo adjustability, making it the most customisable trail bike ever. Six distinct geometry settings let you fine-tune performance for any style and terrain. Adjust the head angle and bottom bracket for optimal stability or clearance.
With aftermarket shock links, you can choose between full 29” wheels or a mixed setup with a 27.5” rear wheel for a more responsive and playful ride. Geometry remains unaffected regardless of your choice.
The SWAT 4.0 system on the Stumpjumper 15 enhances downtube storage, offering the most efficient, weather-resistant, and flush-mounted system available.
Specialized's full suspension bikes are built to withstand years of hard riding and are backed by unmatched support and policies to keep you on the trail. Their lifetime, no-questions-asked replacement of suspension pivot bearings for the original owner is just one way they support their riders.
