Stumpjumper 15 Comp Alloy Specialized 2025

The Stumpjumper 15 Alloy Specialized 2025 is here to eliminate all the pros and cons of the trail. Does it eat bumps like a big bike? Checked.

Short travel control, suspension and efficiency? Double checked. And how about a good dose of customization to make it perfect for the only rider that really matters: you? Checked, checked, checked.

- INCREDIBLE CAPACITY:

The GENIE shock technology combines playful and nimble handling with a bottomless DH feel.

- MAXIMUM CONTROL:

Better traction than the "Bike of the Year" Stumpjumper EVO.

> Unmatched customization: six-position geometry adjustment, mixed wheel or 29", adjustable spring curve and much more.

GENIE-The Magic Carpet Ride:

The biggest innovation of the Stumpjumper 15 Alloy Specialized 2025 is GENIE. This patent-pending air shock technology we invented fulfills the three wishes of any rider: the feel and control of a spring, better bottom-out prevention than a standard air shock, and an adjustable "platform" for a playful ride.

ILLUMINANTE GENIE:

GENIE combines the linear spring rate of a coil spring, improving control in the "bump zone", with the progressive spring rate of an air spring at the end of the travel to prevent bottoming out. Truly, it’s the best of both worlds, coil and air, with more adjustability. Say goodbye to compromises and hello to the future of riding: With 16.3% better bump force management than a traditional air shock, GENIE makes the Stumpy 15 ride like a longer-travel bike. For example, the Stumpjumper 15 Alloy Specialized 2025 (with 145mm rear wheel travel) and our Enduro (170mm travel) use 101mm of travel to absorb a 1080N bump force.

AMPLIFIED TRACTION:

Extensive field testing shows the Stumpjumper 15 Alloy Specialized 2025 with GENIE offers 57% more traction than a standard air shock, as the GENIE technology delivers a flexible, spring-like performance that keeps the wheel in contact with the ground for a greater percentage of time than a typical air shock.

NO MORE BOTTOM-OUTS:

39% fewer bottom-outs than a standard shock. During big impacts, it takes advantage of the rising rate in the last 30% of GENIE's travel. Thanks to this steep two-stage rate rise, GENIE reduces the frequency and severity of bottom-out hits.

OPTIMIZED GEOMETRY:

The geometry of this bike offers the big-bike capability when you need it, an agile feel in playful sections, and nimble, efficient behavior on climbs. The generous cockpit centers you on the bike, optimizing traction and cornering control. The low bottom bracket, slack head angle, and optimized fork offset keep stability in rough terrain.

RIDE YOUR WAY:

The Stumpjumper 15 Alloy Specialized 2025 integrates the benchmark geometric adjustability, making it the most customizable trail bike in history. Six distinct geometry adjustments let you tune performance for any style on any terrain. The head angle and bottom bracket height can be precisely adjusted for stability or clearance.

WHEELS FOR EVERYONE:

With our aftermarket shocks, you can choose between big wheels front and rear or mix it up with a 27.5" rear for a more nimble, playful ride. No matter what you choose, geometry remains unaffected.

TAKE IT ALL WITH YOU:

The SWAT 4.0 on the Stumpjumper 15 Alloy Specialized 2025 increases storage in the down tube, an innovation we pioneered. It’s the most weatherproof storage system yet.

MORE RELIABLE THAN YOU:

Our full-suspension bikes are built to be relentless, designed to withstand years of hard riding and backed by the best support and policies to keep you on the trail. Our unbeatable lifetime warranty, no-questions-asked, on the suspension pivot bearings to the original owner is just one of the ways we’ve got you covered.
