“New bike day” feeling bottled up? That’s what they say about the Stumpjumper. Right here we have a monument to that feeling. It is a radical new trail bike. It promises agility and liveliness. It should feel like an extension of your body.
The Stumpjumper encourages you to levitate up climbs. It wants you to decimate descents. This bike aims to make you rethink how a trail bike should ride.
When designers created the Stumpjumper they had goals. It had to excel on any trail. It had to work for every style of rider. To achieve this, they focused on weight reduction. They did not want to sacrifice durability. They aimed for a stiff, responsive chassis. It still needed to ride light and lively. The geometry should improve everyone’s riding. They wanted the best suspension kinematics. With the new Stumpjumper, you can have your cake and eat it too.
The Stumpjumper offers 130mm of travel. Kinematics were massaged in the suspension. This brings out the best all-round performance. Suspension lab development took countless hours. Field testing also took many hours. The result is a refined mid-travel ripper. It eats big terrain like a gravity-fed beast. It handles like a dream everywhere. It climbs like it has a motor.
The S-Sizing geometry hits the progressive sweet spot. The Stumpjumper is long, low, and slack. It features a short offset fork. It also has a steeper seat tube angle. These numbers combine to make your ride more stable. Your ride becomes more carvealicious. Climbing is more comfortable. It is better everywhere.
FlipChip adjustability allows fine-tuning. This ensures flawless performance. It does not matter which terrain you choose.
Rider-First Engineered frames use a size-specific approach. This affects ride characteristics. It ensures benchmark handling. It provides flawless performance. This is true regardless of frame or rider size. A jump-happy grom can ride an S1. A DH-fiend giant needs the lengthy S6. Both will experience the same ride traits. Expect rail-sharp cornering and balanced stiffness. This is achieved at the lightest-possible weight. The S-Works S-3 size with rear shock weighs just 2250 grams.
