Cascade Components 2021 Stumpjumper EVO Link Installation
TLDRIn this video, David from Catch Gate Components guides viewers through the installation process of the Stumpjumper Link on a 2021 Stumpjumper EVO. The process requires specific tools, including various Allen wrenches, a torque wrench, a shock pump, Loctite, and grease. After removing the rear wheel and necessary bolts, the shock and yoke are removed to facilitate the installation. The stock link is then removed, and bearing spacers are cleaned and reinstalled with new grease. The new link is assembled with spacers and bolts, applying Loctite to the threads for secure installation. The final steps involve torquing all bolts to the correct specifications, checking for clearances, and reassembling the bike with the shock pump used to set the sag to 30 percent. The video concludes with an invitation to visit their website for further inquiries.

Q & A
What is the main topic of the video?
-The main topic of the video is the installation process of a Cascade Components Stumpjumper Link on a 2021 Stumpjumper EVO bike.
What tools are required for the installation process?
-The tools required for the installation process include a six millimeter Allen wrench, a five millimeter Allen wrench, a four millimeter Allen wrench, a torque wrench with six and five millimeter Allen wrench bits, a shock pump, some blue Loctite, and some grease.
How many bolts need to be loosened before installing the link?
-You need to loosen three bolts on one side, the matching bolts on the other side, and the shock mount bolt at the top of the shock.
Why is it recommended to remove the shock and shock yoke entirely?
-The shock and shock yoke are recommended to be removed entirely to prevent scratching the paint and to facilitate the removal of the stock link and bearing spacers.
How many bearing spacers are there and what is their purpose?
-There are eight bearing spacers, and they are used to maintain the correct spacing between the bearings and the frame.
What is the procedure for removing the bearing spacers?
-The bearing spacers are press-fit into the bearings and can be removed using pliers or an Allen wrench by inserting it into the small gap between the two spacers and pushing them out.
What is the importance of applying grease to the bearing spacers and bolts?
-Applying grease to the bearing spacers and bolts helps to reduce friction, protect against corrosion, and ensure a smooth installation process. It also helps the bearing spacer stick to the bearing for easier installation.
Why is it suggested to use blue Loctite on the threads of the bolts?
-Blue Loctite is a threadlocker that, when used on the threads of the bolts, helps to prevent them from loosening over time due to vibration or stress.
How should the final torque specifications for the bolts be determined?
-The final torque specifications for the bolts can be found on the Specialized Service Center website or as part of the website in the service section of Cascade Components.
What is the final step in the installation process after torquing the bolts?
-The final step is to put the wheel back on the bike, let all the air out of the shock, compress the suspension by hand to check for clearances, and then air the shock back up or reinstall the spring and set the sag to 30 percent.
What should be checked for clearance after installing the link and before inflating the shock?
-After installing the link and before inflating the shock, you should check for adequate clearance at the seat stay bridge and around the link to ensure there are no obstructions or contact points that could cause damage.

🔧 Preparing Tools and Removing Components
David from Cascade Components is guiding viewers through the installation of a stump jumper link on a 2021 Stumpjumper EVO. The necessary tools include various Allen wrenches, a torque wrench, a shock pump, blue Loctite, and grease. The process begins with removing the rear wheel and loosening specific bolts to detach the bike's stock link. This includes the three bolts on each side, the shock mount bolt, and removing the shock and shock yoke. The video emphasizes the importance of protecting the bike's paint during this process. After removing the shock, the seat stays are also removed from the yoke. The final step in this segment is to remove the front pivots and the bearing spacers, which are pressed fit into the bearings and can be challenging to remove.
🛠️ Cleaning, Greasing, and Reassembling Components
After cleaning all the hardware and resetting the rubber seals on the bolts, a thin layer of grease is applied to all parts that will touch the bearings. The bearing spacers are then reinstalled in the link, starting with the back two pivot locations. Specialized recommends greasing any surface that contacts the bearing and using blue Loctite on the bolt threads for personal bikes, although it is not demonstrated in the video. The link is installed on the bike by sliding it over the frame and threading in the main pivot bolts. The seat stay pivots are then installed, followed by the shock and shock yoke, taking care to avoid scratches. All bolts are initially snugged up and will be torqued down later in the process.
🔩 Torquing Bolts and Final Checks
With all bolts in place and snugged, the torque wrench is used to tighten them to the correct specifications, which can be found on the Specialized Service Center website or Cascade Components' service section. It is emphasized that every bolt should be torqued properly, regardless of the order. After torquing, the rear wheel is reinstalled, and the bike is checked for clearances by deflating the shock and compressing the suspension by hand. The seat stay bridge and the link are inspected to ensure there is adequate clearance. The final step is to either connect a shock pump to refill the shock or reinstall the spring, followed by setting the sag to 30 percent. The video concludes with an invitation to visit Cascade Components' website for any questions about the installation process or their products.
