Introducing the Stumpjumper 15 Alloy by Specialized—a cutting-edge trail bike designed to excel in every facet of your ride. With its ability to devour bumps like a high-capacity bike while providing the control and efficiency of a short-travel bike, you get unparalleled versatility and performance.

The bike's kinematics ingeniously balance efficiency with optimal bump force management, thanks to a refined anti-squat mechanism. Inspired by previous Stumpjumper models, it offers excellent pedalling characteristics that let you conquer all trails with ease.

Break new ground with the adjusted geometry of this bike—it allows for big bike capacity when necessary, nimble handling in tight sections, and efficient, lively climbing. With the generous cockpit, low bottom bracket, slack head tube angle, and optimised fork offset, you maintain stability even on the most challenging terrains.

But what sets the Stumpjumper 15 Alloy apart is its unrivalled personalisation. Six distinct geometry settings let you perfect your ride according to your style and the terrain. Whether you’re fine-tuning for stability or clearance, the Stumpjumper 15 Alloy has got you covered.

The bike's M5 Alloy chassis has been engineered not just for stiffness, but to ensure you feel connected to the bike. Also, with our aftermarket shock links, this trail bike offers mixed wheels for coil-sprung models and even lets you choose a 27.5" rear to add responsiveness and playfulness to the ride.

Downtube storage, trail endurance, lifetime replacement of suspension pivot bearings for the original owner—the Stumpjumper 15 Alloy is relentless in its mission to keep you on the trail.

Cycle to Work Scheme: Affordable Riding for UK Employees

Unlock a cost-effective way to own the bike of your dreams through the Cycle to Work Scheme. This initiative, available to employees in the UK, lets you enjoy the benefits of cycling while saving on your bike purchase.

With the Cycle to Work Scheme, you can use your pre-tax salary to acquire a brand-new bicycle and essential cycling accessories. This means significant savings for you, as your salary sacrifice reduces both your income tax and National Insurance contributions.

The process is seamless: Choose the bike that suits your needs and budget from our extensive range. Your employer will then set up a salary sacrifice arrangement, spreading the cost of your bike over a specified period, typically 12 to 18 months.

Once the salary sacrifice period ends, you have the option to own the bike outright for a nominal fee, ensuring you get to keep and enjoy your trusted two-wheeled companion for years to come.
