The Stumpjumper 15 is designed to eliminate every compromise in the trail bike world. It devours bumps like a big bike, combines short-travel precision with the perfect balance of playfulness and efficiency, and offers a level of personalisation that makes it your bike, no one else’s.
GENIE Shock Technology is the heart of the Stumpjumper 15, blending the poppy, playful nature of a coil spring with the bottomless feel of a DH bike, delivering a ride that’s smooth and controlled over every type of terrain.
With superior traction compared to the Stumpjumper EVO (our "Bike of the Year"), the Stumpjumper 15 is designed to offer better control, stability, and confidence in all conditions.
Tailor your ride with six-way geometry adjustment, choose between mixed wheels or full 29”, and fine-tune your ride with a tunable spring curve to fit any terrain or riding style.
The GENIE air spring system is the Stumpjumper 15’s biggest innovation. This patent-pending technology gives you the feel and control of a coil spring, with better bottom-out prevention than a standard air spring, and a tunable platform that enhances playfulness. It’s the ultimate shock innovation, giving you the best of both coil and air spring worlds, with full adjustability.
With 16.3% better bump force management than traditional air shocks, GENIE makes the Stumpjumper 15 feel like it has more travel. For example, while the Stumpjumper 15 has 145mm of rear travel, it absorbs bumps with a level of control normally reserved for bikes with 170mm of travel.
GENIE provides 57% more traction than a standard air shock. Its supple, coil-like performance keeps the wheels in constant contact with the ground, improving grip and stability—especially on tricky, technical terrain.
Thanks to GENIE’s rising rate, you’ll experience 39% fewer bottom-outs compared to a standard air spring. The last 30% of the stroke features a pronounced rising rate, helping to cushion big hits and reduce both the frequency and severity of bottom-outs.
The Stumpjumper 15 geometry is designed to give you big bike stability when you need it, and a nimble, responsive feel in tighter sections. The low bottom bracket, slack head tube angle, and optimised fork offset combine to keep you stable on rough trails while maintaining agile handling.
The Stumpjumper 15 is the most adjustable trail bike out there, with six geometry settings that let you dial in the perfect balance between stability, clearance, and agility for any style of riding or terrain.
Customise your ride with either full 29” wheels for smooth, fast rolling or a mixed wheel setup (27.5” rear, 29” front) for a more playful, responsive feel. And with aftermarket shock links, the bike’s geometry remains unchanged no matter which wheel choice you make.
With the SWAT 4.0 system, Stumpjumper 15 sets the standard for downtube storage. It’s the smoothest, most weather-resistant, and flush-mounted system we’ve ever designed—perfect for carrying gear without compromising performance.
Engineered to last, the Stumpjumper 15 comes with lifetime replacement of suspension pivot bearings for the original owner. Designed to take on years of rugged trail riding, this bike is built to endure.
The Stumpjumper 15 isn’t just a bike; it’s a platform for complete customisation, giving you a ride that adapts perfectly to your needs and riding style. Whether you’re hitting fast descents or tight corners, it delivers all the control, comfort, and performance you need.

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.
Experience the freedom of cycling, save money, and reduce your carbon footprint with the Cycle to Work Scheme. Join countless UK employees who have already embraced this eco-friendly and wallet-friendly way of commuting.
