Form Follows Fun

Form Follows Fun

We can make a frame as stiff as we want, but it turns out there’s such a thing as too stiff. To be one with the bike requires engineered compliance in the frame. We engineered the FACT 11M carbon—front end, rear end, and the link between them—as a single unit that hits the stiffness target we established for trail riding.

As the quintessential trail bike, Stumpjumper 15 balances efficiency and optimal bump force management. For the anti-squat on Stumpjumper 15, we struck a balance between the previous Stumpjumper and Stumpjumper EVO, as both had excellent peddling characteristics.

Stumpjumper 15 - All You Need to Know

Stumpjumper 15 Alloy is here to obliterate every trade-off in the trail game. Devour bumps like a big bike? Check. Short-travel control, playfulness, and efficiency? Double check. How about a heaping helping of personalization to make it perfect for the only rider who really matters—you?  Check, check, check.

KINEMATICS PERFECTED: As the quintessential trail bike, Stumpjumper 15 Alloy balances efficiency and optimal bump force management. For the anti-squat on Stumpjumper 15 Alloy, we struck a balance between the previous Stumpjumper and Stumpjumper EVO, as both had excellent pedaling characteristics.

HONED GEOMETRY: This bike’s geometry delivers big bike capability when you need it, a nimble feel in tight sections, and lively, efficient climbing manners. The generous cockpit centers you on the bike, optimizing traction and corner control. The low bottom bracket, slack head tube angle, and optimized fork offset keep things stable in the rough.

RIDE YOUR WAY: The Stumpjumper 15 Alloy seamlessly integrates benchmark geo adjustability, making it the most personalizable trail bike ever. Six distinct geometry settings allow you to hone performance for any style and any terrain. The head angle and bottom bracket can be fine-tuned for stability or clearance.

FORM FOLLOWS FUN: We can make a frame as stiff as we want, but there’s such a thing as too stiff. To be one with the bike requires engineered compliance in the frame. We engineered the M5 Alloy chassis—front end, rear end, and the link between them—as a single unit that hits the stiffness target we established for trail riding.

WHEEL SIZE: All coil-sprung models come with mixed wheels.

WHEEL CHOICE: With our aftermarket link shock links, you can choose between big wheels front and rear or mix things up with a 27.5” rear for a more responsive and playful ride. No matter what you choose, geometry is unaffected.

CARRY IT ALL: SWAT on Stumpjumper 15 elevates downtube storage, an innovation we pioneered.

MORE RELENTLESS THAN YOU: Our full-suspension bikes are built to be relentless, designed to endure years of hard riding, and backed by the best support and programs to keep you on the trail. Our unbeatable lifetime, no-questions-asked replacement suspension pivot bearings to the original owner is just one way we've got you covered.
