Specialized engineers and suspension technologists
attack the whole bike
from chasis to fork to rear shock
and tune everything to work together for one purpose.
It’s through this holistic approach
to development
which we call Total Suspension Integration, or TSI
that we craft the best possible bikes
for specific types of riding
The Specialized pioneered, FOX-made Brain damper
senses changes in the trail and allows the
AFR rear shock
to instantaneously transition
from firm in smooth terrain
to fully active in rough terrain
giving the rider greater efficiency and control.
Maximum traction means greater control.
Because FSR suspension is independent of chain loads
the rear wheel is always free to compress and
rebound in an uninhibited way.
This active suspension keeps the tire on the ground
a greater percentage of the time
which means
more control on the trail
Because the brake caliper is affixed to the
"floating" seatstay
effectively neutralizing braking forces
FSR suspension is decoupled
from braking loads
This means you get control-enhancing
active suspension when you need it most
when you're on the brakes.
Moving weight to the front of the bike is instinctual
The Travel Adjust technology in our front forks
not only makes it easier to rebalance
weight so the front wheel stays firmly planted
on the trail,
it also readjusts the spring rate for the
shorter travel
so the wheel tracks over bumps,
instead of deflecting off,
maintaining control technical ascents.
We pioneered active, independent suspension
over 15 years ago
and have been refining it ever since.
With the new Stumpjumper FSR our experience
and technology deliver the most capable and
versatile trail bike yet.
