THE TRAIL BENCHMARK — When we set out to design the all-new
Stumpjumper, we pursued some hefty goals. It had to excel on any kind of trail,
for every style of rider. To achieve that, we went after serious weight
reduction without sacrificing durability, a stiff, responsive chassis that
still rides light and lively, geometry that improves everyone’s riding, and the
best suspension kinematics we know how to design. Turns out, you can have your
cake and eat it too with the new Stumpjumper.

the kinematics of the Stumpjumper suspension to bring out the very best
all-round performance possible in a 130mm package. Countless hours of
suspension lab development and field testing created a refined mid-travel
ripper that eats big terrain like a gravity fed beast, handles like a dream
everywhere, and climbs like it has a motor.

PROGRESSIVE GEOMETRY — The S-Sizing geometry of the new
Stumpjumper hits the progressive sweet spot. It’s long, low and slack, with a
short offset fork and a steeper seat tube angle. These numbers combine to make
your ride more stable, more carvealicious, more comfortable climbing, more
better everywhere. With FlipChip adjustability you’re able to further fine-tune
your fit, ensuring that your new Stumpjumper performs flawlessly on whatever
terrain you choose.

Engineered™ frames use a size-specific approach to ride characteristics that
ensures benchmark handling and flawless performance, regardless of frame or
rider size. Whether you’re a jump-happy grom riding an S1, or a DH-fiend giant
in need of the lengthy S6, you’ll experience the same ride traits – rail-sharp
cornering and balanced front and rear stiffness – at the lightest-possible
weight, And by light, we mean real light: 2,250 grams (S-Works, S-3 size, with
rear shock).
