REDSHIFT SPORTS ShockStop Pro Suspension Seatpost RT
INSTRUCTIONS
Thanks for choosing the Redshift Sports ShockStop PRO Suspension Seatpost RT! The Shockstop PRO Short Travel seatpost delivers the perfect “Race-Tuned” suspension feel for performance-focused riders. The progressive spring rate of the two internal elastomers delivers 20mm of refined suspension movement. This seatpost is different than other seatposts, so please read these instructions and warnings completely before installing or using the seatpost. If you are unfamiliar with bike maintenance or seatpost installation, or if you lack the required tools, please visit your local bike shop or contact Redshift Sports customer service for assistance (support@redshiftsports.com). Improper installation or use may void the product’s warranty. Check out www.redshiftsports.com/faq for instructional videos and additional resources.
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 different diameter seat tube without an appropriate shim may cause damage or failure of the seatpost or bicycle frame.

WARNING
- 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 specifications (or the bike manufacturer’s torque specification). Periodically check all fasteners for tightness using a torque wrench, since fasteners can loosen under the influence 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.3
- Periodically clean and inspect all surfaces of this component for hairline cracks or signs of damage. If you find any cracks or damage, immediately cease using the part and contact Redshift Sports customer service.
- This seatpost is intended for road and light off-road use only. It is NOT intended for extreme off-road use or jumping. Unintended use may lead to breakage of the component, possibly causing serious injury or death.
- For metal-framed bicycles, ensure that the post and the inside of the seat tube are covered with a thin layer of bicycle grease prior to installation. Failure to do so may cause the post to seize inside the bicycle frame.
INSTALLING THE SEATPOST
NOTE: TO ACCOUNT FOR SAG THE INITIAL SUSPENSION TRAVEL WHEN YOU SIT DOWN, YOUR SADDLE SHOULD BE POSITIONED APPROXIMATELY 5 MM HIGHER AND 4 MM FURTHER FORWARD THAN YOUR SADDLE POSITION WHEN USING A RIGID SEATPOST.
-
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.
-
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 speciÿed by the frame manufacturer.
-
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.
-
Tighten the bicycle’s seatpost clamp bolt according to the bicycle manufacturer’s torque speciÿcation.
-
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.
-
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.
-
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.
-
Position the saddle in the desired fore-aft position within the saddle clamp.
-
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 FORWARDË™, 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. -
Install fender against rear linkage by placing the fender magnet on the front saddle clamp bolt.
-
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 www.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.
ADJUSTING ELASTOMERS
The seatpost is designed to be ridden with no adjustment to the elastomers. The as-built conÿguration is designed to work for the vast majority of riders and riding conditions. Additional (extra soft or extra rm) elastomers are available (sold separately), but we strongly recommend ÿrst riding with the standard elastomer combination before considering changes.
If you determine that you would prefer to try a softer or sti˛er elastomer, you will ÿnd instructions for changing elastomers included with the additional elastomer kit.
