Setting The Preload; Installing The Seatpost; Maintenance - REDSHIFT ShockStop Instructions

SETTING THE PRELOAD

A preload adjustment of "1" is the softest setting. Turning the preload plug further into the seatpost
will increase the sti ness and rm up the suspension. This can be done by hand, or if necessary, a
4mm hex wrench can be inserted through the side holes in the plug to provide additional leverage.
The rmest setting is with the preload plug turned all the way in (it does not need to be tight).

As a general guideline for a comfortable setting, set the preload so that the suspension mechanism
moves down approximately 6mm (20%) from the top of its travel range when you are sitting in a
neutral riding position. The 20% sag point can be determined visually by removing the fender and
observing the linkage pivot shaft from the side (it may be helpful to enlist the help of a friend).
Adjust the preload setting such that the end of the silver pivot shaft is barely (but completely)
hidden from view by the side of the post when you are seated in a neutral riding position.
UNLOADED POSITION

Another general guideline is the "bounce test". While riding on at ground, raise up o the saddle
and then sit down with some force to bounce the suspension. If it's easy for you to reach the full
range of travel and you're getting a noticeable "bottom-out" feel at the end of travel, you may want
to increase the preload.

INSTALLING THE SEATPOST

STOP! THE SHOCKSTOP SEATPOST MUST BE SET UP WITH THE APPROPRIATE PRELOAD ADJUSTMENT
!
AND/OR SPRING COMBINATION BEFORE INSTALLING. SEE 'CHOOSING YOUR SEATPOST SETUP" AND
"SETTING THE PRELOAD" SECTIONS FIRST!
NOTE: TO ACCOUNT FOR SUGGESTED 20% SAG THE INITIAL SUSPENSION TRAVEL WHEN YOU SIT
DOWN , YOUR SADDLE SHOULD BE POSITIONED 6 MM HIGHER AND 5 MM FURTHER FORWARD THAN
YOUR SADDLE POSITION WHEN USING A RIGID SEATPOST.
!
1. Prior to removing your existing post, you may wish to measure and record the existing height,
fore-aft position, and tilt angle of your saddle for future reference.
2. Remove your existing seatpost and saddle. Clean the inside of the bicycle's seat tube and ensure that
the inside of the seat tube is free of burrs and sharp edges. Apply a thin layer of grease to the inside of
the seat tube. DO NOT grease seat tubes of carbon frames unless speci ed by the frame manufacturer.
3. Insert the seatpost into your bicycle seat tube to the approximate desired height. Do not twist the
seatpost during insertion. Ensure that the seatpost is inserted far enough into the seat tube that the
minimum insertion line on the seatpost is not visible above the frame's seatpost clamp.
4. Tighten the bicycle's seatpost clamp bolt according to the bicycle manufacturer's torque speci cation.
5. Use a 4mm hex wrench to loosen the saddle clamp bolts
until the threads are barely engaged in the nuts. Install
the saddle between the upper and lower clamp. Some
saddle rail shapes may require the bolts to be fully
unthreaded from the nuts to install the saddle.
NOTE: POSITION LOWER CLAMP WITH LONGER RAIL
SUPPORTS TOWARD THE BACK OF THE SADDLE
6. If installing the seatpost fender, completely remove rear
saddle clamp bolt from the nut, loop fender o-ring
around bolt under the upper saddle clamp, and reinstall
bolt as shown in the picture.
7. Use a 4mm hex wrench to lightly tighten the front and rear clamp bolts to
hold the saddle in place. Make sure that the hex wrench is inserted completely
into the hex hole in the bolt heads to avoid damaging or stripping the bolt.
8. Position the saddle in the desired fore-aft position within the saddle clamp.
9. Use a 4mm hex wrench to adjust the saddle angle by tightening or loosening the front or rear saddle
clamp bolts. Once the desired saddle angle is achieved, alternately tighten both bolts in quarter turn
increments, using a torque wrench for the front bolt and a standard hex wrench for the rear bolt. Stop
tightening both bolts once the front bolt reaches 6 N-m of torque. Do not exceed 9 N-m.
WARNING! ADJUSTING THE SADDLE CLAMP TILT BEYOND ITS RANGE MAY DAMAGE THE SEATPOST:
!
WHEN TIGHTENING THE REAR BOLT TILTING REARWARD , THE UPPER SADDLE CLAMP MUST NOT BE IN
CONTACT WITH THE REAR PORTION OF THE LINKAGE MECHANISM.
WHEN TIGHTENING THE FRONT BOLT TILTING FORWARD , THERE MUST BE A GAP OF
AT LEAST 2MM BETWEEN THE UPPER SADDLE CLAMP AND THE UPPER LINKAGE.
!
WARNING! DO NOT OVER TIGHTEN SADDLE CLAMP BOLTS! OVERTIGHTENING MAY LEAD TO
SEATPOST FAILURE, POTENTIALLY CAUSING SERIOUS INJURY OR DEATH. ALWAYS USE A TORQUE
WRENCH WHEN ADJUSTING SADDLE CLAMP BOLTS.
11. Install fender against rear linkage by placing the fender magnet on the front saddle clamp bolt.
12. Adjust saddle height if necessary.

MAINTENANCE

The ShockStop Seatpost is designed to run quietly and smoothly with minimal maintenance. If you
encounter any issues with your seatpost, please visit redshiftsports.com/faq for instructional videos and
troubleshooting help, or contact us at support@redshiftsports.com.
NOTE: DO NOT USE GREASE OR ANY LUBRICATION ON PIVOT BUSHINGS. THEY ARE DESIGNED TO
RUN DRY AND WILL PERFORM BETTER AND LAST LONGER WITH NO LUBRICANT.
PRO TIP: Stick the
fender magnet to
your saddle's rails to
keep it out of the
way while you
O-RING
make adjustments.
