The S-Works Stumpjumper 15 LTD trail bike is here to obliterate every trade-off in the trail game. Devour bumps like a big bike? Check. Short-travel control and optimal pedaling efficiency? Double check. Swapping between those two scenarios automatically without ever flipping a switch? Check, check, check. Meet the all-new S-Works Stumpjumper LTD with FOX Live Valve Neo.KINEMATICS PERFECTED — 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 pedaling characteristics.IT’S [A]LIVE — No, we haven’t finally created a sentient bike… It’s FOX’s brand new Live Valve Neo system equipped on S-Works Stumpjumper 15 LTD. A lightning-fast wireless rear suspension system that provides infinite tuning options through the FOX Bike app, and the best possible combination of XC pedaling efficiency and enduro descending capability—faster than the blink of an eye.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 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, any terrain. 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 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.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 4.0 on Stumpjumper 15 elevates downtube storage, an innovation we pioneered. It’s the smoothest operating, most weather-resistant, flush-mounted system ever.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 policies to keep you on the trail. Our unbeatable lifetime, no-questions-asked replacement suspension pivot bearings to the original owner (one bearing set, per bike, per year) is just one way we've got you covered. See your local Specialized Retailer for details.

Awesome
this bike is worth the ride…. . started MTB in 2022 with a stumpjumper evo comp alloy……. thinking it can’t get any better……i was wrong…. . they did it. Took a while to tune the suspension…but when i did. . …. it was one of those moments where you sit at the trail head…watch this beautiful bike…. and a tear forms. Pedals well, climbs as if it has a motor, it breezes through the rocks and roots…. and golly, it’s fast. Thanks to the maven brakes…. built to handle the speed. The bike is just awesome.

DEFINITELY the best trail bike!
Got the bike a couple months ago and loved it the moment I saw it. Trails or urban this thing is a beast, the live valve system is amazing and if you don’t mind a little more weight I would recommend the handlebar switch to switch modes on the fly. If you’re riding urban it stays stiff so you have more pedal efficiency and on trails both the fork and shock eat up roots, rocks and anything else the trail has to offer. Setting the whole bike up was a breeze, all of the instructions and information on all of the parts are all the Fox bike app. Thank you so much bike source Charlotte!
