DocumentDocument4 9 3 SHOCKSTOP ENDURANCE SUSPENISON SEATPOST 11 2 INSTRUCTIONS 5 Thanks for choosing the Redshift Sports ShockStop Suspension Seatpost! The 10 seatpost provides tunable suspension to increase comfort and performance during your ride. 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 circular seat tube. It is important to check that your seat tube matches the diameter of your seatpost. 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. 8 6 1 7 # QTY PART NAME 1 1 Seatpost & Linkage 2 1 Lower Saddle Clamp 3 1 Upper Saddle Clamp 4 2 Saddle Clamp Nuts 5 2 Saddle Clamp Bolts 6 1 Fender 7 1 Preload Adjustment Plug 8 1* Spring Spacer(s)* 9 1* Spring End Cap(s)* 10 1 Main Spring 11 1 Inner Spring (Oponal) *350mm seatpost length shown. Longer seatposts have more spacers. 280mm seatpost has a second end cap in place of the spacer. CHOOSING YOUR SEATPOST SETUP The Shockstop seatpost is fully adjustable to fit you and your riding preference. Different springs can be used to make large adjustments to the stiffness, and then fine-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 different riders may prefer stiffer or softer settings than the chart recommends. Riding position and terrain can also dramatically affect the required preload setting, so don't be afraid to experiment with different settings to find your best ride!

NOTE: THE OUTER SPRING MUST ALWAYS BE INSTALLED. The inner spring can be optionally added when a stiffer 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 of the bottom of the seatpost: spring spacer(s) (not included with 280mm length), spring(s), and spring endcap(s). 4. Insert or remove the inner spring inside the outer spring 5. Apply grease to the outside of outer spring and end caps, if needed. 6. Turn seatpost upside-down 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 cap(s) should be sitting flat against the spring. When fully installed, the spacer(s) (350mm length or greater) or lower endcap (280mm length) should sit a few millimeters inset from the bottom of the seatpost. If the internal parts protrude from the bottom of the post, make sure the suspension linkages are fully extended and make sure the spring end caps are sitting flat against the spring. 7. Re-install preload plug and adjust as-needed for desired suspension firmness. ! WARNING Lorem ipsum Main Spring Optional Inner Spring (place inside Main Spring) Spacer(s) Preload Plug *350mm seatpost length shown. Longer seatposts have more spacers. 280mm seatpost has a second end cap in place of the spacer. · 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 circular seat tube. It may be used with larger seat tube diameters by using an appropriate diameter shim at least 100mm (4 in.) in length. · Do not raise the post beyond the minimum insertion line. · 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. · 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. · Intended Use: ASTM F2043 Class 2 - For on and off-road riding and drops less than 15cm (6"). It is NOT intended for extreme off-road use or jumping. · Excessive "bottom-out" of the suspension seatpost (i.e. riding with insufficient preload) can cause damage or result in breakage of the component. · Seatpost is not compatible with rear luggage racks which clamp directly to the seatpost tube. · Never place your hands or fingers near the seatpost linkages while riding. Doing so may cause pinching or SETTING THE PRELOAD A preload adjustment of "1" is the softest setting. Turning the preload plug further into the seatpost will increase the stiffness and firm 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 firmest setting is with the preload plug turned all the way in (it does not need to be tight). Warning! X Preload set below minimum OK Preload set at 1 (minimum) OK Preload set at 3.5 OK Preload set at 5 (maximum) ! WARNING! DO NOT SET THE PRELOAD ADJUSTMENT BELOW THE "1" MARK. DOING SO CAN CAUSE INTERNAL PARTS TO LOOSEN OR FALL OUT WHILE RIDING. As shown in the "Suggested Preload Range" table on page 1, there is a wide range of spring and preload settings that are appropriate depending on your preferred ride feel. As a starting point for a comfort-oriented 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. Use this as a starting point for a comfort-oriented setting, but feel free to adjust the preload firmer or softer once you start riding. UNLOADED POSITION 20% SAG POSITION Pivot shaft visible from side view Pivot shaft hidden from side view L Another general guideline is the "bounce test". While riding on flat ground, raise up off 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. ! PINCH WARNING! ! ! WARNING!

Warranty details and return instructions for all Redshift products can be found at www.redshiftsports.com/warranty. 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 specified 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 specification. 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. O-RING TETHER PRO TIP: Stick the fender magnet to your saddle's rails to keep it out of the way while you make adjustments. FRONT OF SADDLE 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. BACK OF SADDLE 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.
