With adjustable ProPedal (PP), riders benefit from
maximum pedaling efficiency traction, and square
edge performance, eliminating first-strike harshness
when activated, to plush, downhill loving travel when
the ProPedal is deactivated. With rebound adjustment,
and adjustable bottom-out resistance, the DHX Air
offers rider-adjustable tuning for any adventure.
The DHX® Air offers riders heavy-duty trail riding
shock performance in an ultra-lightweight package. The
extra-large volume air spring and position-sensitive,
velocity sensitive Boost Valve damping offer an
amazing amount of stutter-bump through big hit
sensitivity, and virtually bottomless suspension
performance in any type of terrain.

Rebound damping controls how quickly the
suspension returns after being compressed and
gives you a predictable and controlled ride, while
maintaining traction.
Assessing rebound by simply pushing on the
handle bars or seat does not indicate the
performance of the system in a dynamic
environment. Save your judgment of rebound
performance for a test section of trail.
Slower rebound
Faster rebound
REBOUND TOO FAST
REBOUND TOO SLOW
If rebound is too fast the bike will be
unstable while pedaling and riding
through shallow bumps. The unsettling
effect is noticed as your body weight is
pitched over the bike.
If rebound is too slow, there will be
insufficient recovery between bumps
to ensure successive bumps are
absorbed. Harshness will be noticed
on longer rough sections.

PROPEDAL
6
The ProPedal (PP) adjuster on the DHX Air is a
wide range low-speed compression (LSC) adjuster.
LSC damping refers to the damper force
generated at low damper shaft speeds, as occurs
with rider induced suspension movement.
Firmer PP

Clockwise adjustment
Counter clockwise adjustment
ADJ SETTING - PP MIN
Descending, technical terrain and trails
that require maximum traction and
compliance.
ADJ SETTING - PP MAX
Ascents, smooth terrain and trails that
require a firm platform for pedaling
efficiency.
PP adjustment provides a means for attaining a
firm platform for pedalling efficiency on a long
travel trail bike, allowing the rider to efficiently
climb, yet descend with comfort and control when
the PP lever is in the minimum setting.

BOOST VALVE
Boost Valve (BV) technology delivers position
sensitive damping, providing support throughout
the stroke of the damper and resistance to
bottom-out.
Boost Valve Range (PSI) affects the degree of Boost Valve control, and can be utilised to prevent compression overshoot (excessive travel use) throughout the stroke.
PSI TOO LOW
Excessive use of travel / compression
overshoot and lack of support
throughout the compression stroke
(wallow).
PSI TOO HIGH
A lack of bump compliance throughout
the compression stroke. Overall lack
of travel use.

Clockwise adjustment
Counter clockwise adjustment
Boost Valve (BV) technology delivers position
sensitive damping, providing support throughout
the stroke of the damper and resistance to
bottom-out.
Bottom-Out Control (BOC) affects the system’s resistance to bottom-out, offering relatively independent adjustment of the maximum bottom-out resistance.
BOC TOO SOFT
Excessive bottom-out, while initial bump
compliance and travel use are ideal.
BOC TOO FIRM
A lack of full travel use, while initial
control of bump input is ideal.
