How To Service A Mountain Bike Shock

Mountain biking is a thrilling outdoor activity that entails lots of speed and adrenaline. It's a great way to stay fit, explore the outdoors, and create unforgettable memories. More importantly, it requires the right equipment to optimize your performance, and the mountain bike shock is one of the most critical components of your bike. The shock provides a comfortable ride by absorbing impacts from bumps, jumps, and landing drops that you encounter while biking. It's inevitable that after some time of riding, the shock may need servicing, and that's where this guide comes in handy. In this blog, we will give you a step-by-step guide on how to service your mountain bike shock, so you can enhance your bike's function and prolong its lifespan.

Removing The Mountain Bike Shock

Firstly, before attempting to service the shock, it's crucial to remove it from the bike. The process may vary depending on the type of shock and bike frame you have, but the basic steps include disconnecting the shock from your bike. Ensure that you deflate the air pressure and disconnect the shock, which is typically connected via two mounting bolts. Use a thin-bladed screwdriver to remove circlips and extract the bolt from the back. Take note of the orientation of the shock, as some designs have a specific top and bottom.

Disassembly Of The Mountain Bike Shock

After removing the shock, you can proceed to disassemble it, but gently take out the main shaft assembly and reservoir. Next, remove the air can & air sleeve assembly, and then remove the shock shaft from the damper and pull the piston out from the bottom. Make sure you keep the parts orderly and keep a safe distance from the damper, as it has pressurized oil that can cause serious harm.

Cleaning Of The Mountain Bike Shock

Cleaning the shock is essential for removing dirt, grime, and other elements that may have accumulated inside your shock. Use a clean and damp cloth to wipe the inner and outer parts of the shock. Carefully inspect the shock for cracks, bent parts and mangled seals. You may also use an automotive brake cleaner if you have one to clean the shock. Generally, avoid using any solvents other than isopropyl alcohol as it can degrade the shock's seals and rubber parts.

Rebuilding The Mountain Bike Shock

After the shock is clean, start rebuilding it. Begin with lubricating all the O-rings with shock oil, such as Finish Line or Maxima Suspension fluid, then pack the seals and dust wipers with grease. Next, pressurize your shock's air can using a shock pump. Then reassemble all the small components of your shock, carefully paying attention to their orientation. Once all pieces are assembled, reinstall it on your bike and ensure that the shock has been properly tightened to the recommended torque settings.

Testing The Shock

The last step entails testing the shock after installation. Inflate the air shock to the recommended PSI and set up sag. With little to no weight on the saddle, the shock should sag at around 30% of its travel. If it's too much or too little, adjust the air pressure accordingly. And that's it, you're all set to test ride.

Servicing your mountain bike shock is essential for optimal bike performance, longevity, and a comfortable ride. This guide provides a step-by-step process you can follow to service your mountain bike shock. However, if you don't feel comfortable performing maintenance on your bike, it's best to seek professional help. Remember to always ride safe and enjoy the trail!
