Sure! Here are the step-by-step instructions on how to change the elastomers on the REDSHIFT Shockstop Pro Suspension Seatpost RT, as provided in the instruction manual:
1. To remove the rebound elastomer:
- Use a 2.5mm hex wrench to tighten the rebound elastomer set xxxx (#1) by turning it clockwise until the suspension mechanism moves enough for the rebound elastomer (#2) to freely spin around the set xxxx .
- Rotate the rebound elastomer (#2) until the open end is visible when looking from the side.
- Press sideways on the rebound elastomer (#2) from the open end to get it to pop off of the set xxxx and fall out the other side of the linkage. Be careful not to lose the rebound elastomer. You may need to use a small hex wrench or other thin tool to assist with removing the elastomer.
- Once the rebound elastomer (#2) is removed, loosen the rebound elastomer set xxxx (#1) by turning it counter-clockwise until the set xxxx is no longer visible between the linkages. If you can push the suspension mechanism up until the two linkages are touching, then you have turned out the set xxxx far enough.
2. To remove the front lower shaft:
- Use a 2.5mm hex wrench to loosen the lower front shaft set xxxx (#3) by turning it counter-clockwise at least 2 full turns. You may need to push the suspension mechanism down to make the set xxxx more accessible.
- Press the lower front shaft (#4) out. You may need to use a thin tool like a pen or a pencil to assist with pressing out the shaft. Depending on the size and orientation of your saddle, you may need to remove the saddle to access the internal parts of the seatpost.
3. To remove the internals:
- Pull upwards on the ball and socket joint (#5). The elastomers may come out with the ball and socket, but if not, you can turn the seatpost upside down and lightly hit it with your hand to shake them out. Note that the grease may cause the elastomer end caps to stick to each other and to the bottom of the ball and socket assembly.
- Make sure no grit or dirt gets into the seatpost. If necessary, clean and re-grease the inside surface of the post.
4. To reinstall the internals:
- If not already greased, apply grease to all surfaces of the elastomers, including the top and bottom end caps.
- Install the elastomers inside the post. If you're using two different durometer elastomers, place the softer elastomer in first, followed by the stiffer elastomer. Note that both elastomers must be installed for the seatpost to function properly.
- Clean and re-grease the bottom and outer diameter of the socket joint (the surface that runs along the inside of the post).
- Install the ball and socket joint (#5) so that the half-round cutout is oriented to engage with the lower linkage bushing (#6).
- Rotate the entire mechanism until the lower linkage shaft hole lines up with the holes in the post.
- Ensure that the half-round cutout on top of the ball and socket joint is engaged with the bushing at the bottom of the lower linkage (#6).
- Reinstall the lower front pivot shaft (#4) with light hand pressure.
- Tighten the lower front shaft set xxxx (#3) and torque it to 4Nm.
5. To reinstall the rebound elastomer:
- Tighten the rebound elastomer set xxxx (#1) until the linkages are separated enough to freely install the rebound elastomer.
- Install the rebound elastomer (#2) over the set xxxx . It may be helpful to slightly bend open the elastomer to help get it on the set xxxx .
- Loosen the rebound elastomer set xxxx (#1) until the set xxxx is no longer causing the suspension mechanism to move. When looking at the front of the linkage, the top of the set xxxx should be just 1 or 2 turns below the face of the linkage.
