Unrivaled suspension kinematics, sublime handling, and perfectly tuned frame stiffness—the Stumpjumper Comp is the definitive full-carbon trail bike. With all-new geometry, advanced suspension design, and thoughtful component choices, it delivers benchmark trail performance at an accessible price point.
Highlights
The Trail Benchmark
When designing the all-new Stumpjumper, we set out to create a bike that excels on every trail for every style of rider. The result is a lightweight yet incredibly durable chassis with geometry that improves control, comfort, and capability—paired with the best suspension kinematics we’ve ever engineered.
The Sweetest 130mm of Travel You’ll Ever Ride
Extensive suspension lab work and field testing led to a mid-travel bike that feels bottomless on descents yet climbs with exceptional efficiency. The Stumpjumper devours technical terrain, carves with precision, and pedals like it’s powered.
Progressive Geometry
S-Sizing geometry hits the modern sweet spot: long, low, and slack with a steep seat tube angle and short offset fork. Combined with a FlipChip for fine-tuning, you can easily adapt the Stumpjumper to your local terrain and riding style.
Rider-First Engineered™
Every frame size delivers identical handling and performance characteristics. From S1 to S6, each rider experiences the same balance, stiffness, and precision that make the Stumpjumper the reference point for trail bikes.
SWAT™ Integration
The built-in SWAT™ storage door provides easy access to tools, tubes, and snacks—so you can ditch the pack and keep everything you need inside the downtube.
