29-Inch Plus Wheel

With 140mm/125mm of travel, the Optic condenses years of technology from long travel bikes into a lightweight package that’s as comfortable tearing up climbs as it is tackling challenging descents. The VPSHP suspension layout provides increased rearward axle path and an idler to manage pedal feedback, keeping Optic’s playful roots, while punching above its weight when the trails get rough. GEOMETRY Coming in five frame sizes (1,2,3,4,5) to support rider heights up to 6’5" (196cm), allows you to choose the frame size that best fits your body and riding preferences. Rear centres and seat tube angles are varied by frame size to ensure consistent rider weight distribution, and short seat tubes with long dropper posts keep the saddle out of the way on technical descents. WHEELS: Available with a 27.5" rear wheel, as well as 29" in some markets. Swapping the linkarm and lower shock mount with the “Missing Link Kit" converts between 27.5" and 29" to let you pick the wheelsize that suits you best, while maintaining geometry and kinematics to ensure consistent fit and bike setup. - Optic Carbon Frame + RockShox Pike Select fork - RockShox Super Deluxe Select+ shock - Co-molded frame protection - Proprietary chainguide and idler design - OneUp EDC tool - Weight (S3): 15.6 kg / 34.2 lbs

The Stumpjumper 15 is designed to eliminate all trade-offs in the trail biking experience. It combines the ability to absorb bumps like a larger bike, and offers short-travel control, playfulness, and efficiency—all while providing extensive personalization options to suit the unique rider—you. **BREAKTHROUGH CAPABILITY:** The GENIE Shock Technology delivers a lively, playful ride while ensuring a bottomless downhill feel. **ULTIMATE CONTROL:** This bike boasts significantly better traction than the award-winning Stumpjumper EVO. **UNMATCHED PERSONALIZATION:** With features like six-way geometry adjustment, options for mixed wheel sizes or 29” wheels, and a tunable spring curve, customization is at your fingertips. **GENIE—The Magic Carpet Ride:** The standout innovation of the Stumpjumper 15 is the GENIE. This patent-pending air spring technology allows every trail rider to enjoy the comfort and control of a coil spring while also preventing bottom-outs better than traditional air springs. Plus, it offers a tunable platform for a more playful riding experience. **ILLUMINATING GENIE:** GENIE merges the control-enhancing properties of a linear coil spring through the "bump zone" with the progressive spring rate of an air spring at the end of its stroke, effectively preventing bottom-outs. It's the best of both worlds—coiled comfort and air spring adaptability—without any compromises. **WHAT BUMP?:** With 16.3% improved bump force management compared to traditional air-sprung shocks, the GENIE makes the Stumpjumper 15 feel like it has more travel. For instance, both the Stumpjumper 15 (with 145 mm rear-wheel travel) and our Enduro bike (with 170 mm travel) utilize 101 mm of travel to absorb a 1080 N bump force. **TRACTION GALORE:** Field testing has shown that the Stumpjumper 15, equipped with GENIE technology, provides 57% better traction than standard air-sprung shocks. This technology offers supple, coil-like performance, keeping the wheel in contact with the ground more effectively than typical air springs. **BYE, BYE, BOTTOM-OUTS:** Experience 39% fewer bottom-outs compared to standard air springs. During significant impacts, the rising rate in the last 30% of the GENIE stroke benefits the rider by reducing both the frequency and severity of bottom-outs. **HONED GEOMETRY:** The geometry of this bike ensures big bike capability when needed, a nimble sensation in tight areas, and efficient climbing manners. The spacious cockpit positions you optimally, enhancing traction and cornering control. Its low bottom bracket, slack head tube angle, and optimized fork offset contribute to stability on rough terrain. **RIDE YOUR WAY:** The Stumpjumper 15 features exceptional geo adjustability, making it the most customizable trail bike available. With six unique geometry settings, you can fine-tune performance to match any riding style and terrain. Adjust the head angle and bottom bracket height for enhanced stability or clearance. **WHEEL CHOICE:** Utilizing our aftermarket shock links, you can select either 29” wheels front and rear or opt for a mixed setup with a 27.5” rear wheel for a more responsive, playful experience. Regardless of your choice, the geometry remains unaffected. **CARRY IT ALL:** The SWAT 4.0 system on the Stumpjumper 15 enhances downtube storage, a feature we pioneered. It is the smoothest, most weather-resistant, flush-mounted system available. **MORE RELENTLESS THAN YOU:** Our full-suspension bikes are built for endurance, designed to withstand years of heavy riding, and supported by excellent service and policies ensuring you stay on the trail. Our lifetime guarantee for no-questions-asked replacement of suspension pivot bearings for the original owner is just one way we show our commitment. - Lightweight FACT 11m carbon chassis and rear-end. - Ride Dynamics-tuned FOX FLOAT Performance Elite with Specialized GENIE Shock Technology, offering a highly adjustable 2-position open and firm mode with a 3-position open mode compression adjuster. - Supportive and tunable FOX FLOAT 36 Performance Elite fork with GRIP X2 damper. - Strong and reliable Roval Traverse wheels with DT Swiss 370 hub. - Smooth and precise SRAM GX Eagle T-Type AXS drivetrain. - Powerful and dependable SRAM Maven Bronze 4-piston brakes. - Adjustable travel with the PNW LOAM dropper post. - Lifetime replacement of suspension pivot bearings for the original owner. - Compatible exclusively with electronic drivetrains.
