This seatpost is di erent than other

instructions and warnings completely
before installing or using the seatpost. If
you are unfamiliar with bike

COMPATIBILITY

This seatpost is designed for bicycle
frames with a 27.2mm diameter
circular seat tube. The seatpost may be
used with larger diameter seat tubes by
using the correct diameter seatpost
shim. In order to reduce stresses on the
post and frame, only use seatpost
shims of at least 100 mm (4 in.) in
length. Using the seatpost in a di erent
diameter seat tube without an
appropriate shim may cause damage or
failure of the seatpost or bicycle frame.
• Failure to follow these instructions and warnings may result in malfunction or breakage of this component,
possibly causing serious injury or death.
• Always use a torque wrench when installing or adjusting fasteners, and always tighten to Redshift torque
speci cations (or the bike manufacturer's torque speci cation). Periodically check all fasteners for tightness
using a torque wrench, since fasteners can loosen under the in uence of road vibration.
• This seatpost is designed for use in a 27.2 mm diameter seatpost. It may be used with larger seat tube
diameters by using an appropriate diameter shim longer than 100mm (4 in.) in length.
• Do not raise the post beyond the minimum insertion line.

CHOOSING YOUR SEATPOST SETUP
The Shockstop seatpost is fully adjustable to t you and
your riding preference. Di erent springs can be used to
make large adjustments to the sti ness, and then
ne-tuning can be accomplished by adjusting the preload
plug located at the bottom of the seatpost.
The chart shown here is a good starting point, but
di erent riders may prefer sti er or softer settings
than the chart recommends. Riding position and
terrain can also dramatically a ect the required preload
setting, so don't be afraid to experiment with di erent
settings to nd your best ride!

CHANGING SPRINGS

The ShockStop Seatpost ships with 2 springs – an outer spring which
comes pre-installed in the seatpost, and an inner spring which is
included in the package.
NOTE: THE OUTER SPRING MUST ALWAYS BE INSTALLED. The
inner spring can be optionally added when a sti er spring rate is
desired.
1. Remove seatpost from frame.
2. Turn seatpost upside-down and completely unscrew the preload plug.
This can be done by hand or by inserting a 4 mm hex wrench through
the side holes in the plug to provide additional leverage.
3. Tilt seatpost to slide internal components out the bottom of the
seatpost: spring spacer, spring(s) and spring end caps.
4. Insert or remove the inner spring inside the outer spring
5. Apply grease to the outside of the outer spring and spring end caps, if
needed.
6. Turn seatpost upside-down again and reinstall the internal
components, noting the order in the picture. The protective material
around the outer spring should be oriented towards the top of the
seatpost. The spring end caps should be sitting at against the
spring. When fully installed, the spacer tube should sit a few
millimeters inset from the bottom of the seatpost. If the spacer tube
is protruding from the bottom of the post, make sure the suspension
linkages are fully extended and make sure the spring end caps are
sitting at against the spring.
7. Re-install preload plug and adjust as-needed for desired suspension
rmness.
