Installation of the SR Suntour Edge R Rear Shock
Installing the Edge R rear shock requires precise steps to ensure optimal performance and durability. Follow these steps carefully to ensure a proper fit and function.
Step 1: Remove the Existing Shock (if applicable)
If replacing an old shock, start by removing the previous unit. Use a 5mm Allen wrench [paid link] to loosen the mounting bolts on both ends of the shock. Be sure to keep the hardware safe for re-use or replacement.
Step 2: Prepare the Frame and New Shock
Before installing the Edge R rear shock, clean the mounting points on the frame and apply a thin layer of grease to prevent corrosion. It is also crucial to check that the shock fits properly into the frame’s shock mountings.
Step 3: Attach the Shock to the Frame
Align the shock’s eyelets with the frame’s shock mounts. Secure the shock by tightening the mounting bolts using the appropriate size Allen wrench. Ensure that the bolts are tightened to the manufacturer’s recommended torque settings, typically between 10-12Nm, using a torque wrench [paid link] for accuracy.
Step 4: Set the Air Pressure
Once the shock is mounted, use a shock pump to adjust the air pressure to your preferred level. The Edge R features an air spring that requires precise tuning based on your weight and riding style. Check the manufacturer’s guidelines for recommended air pressure ranges.
Step 5: Test the Suspension
Before heading out for a ride, perform a test of the shock’s functionality. Compress the shock manually and verify that it rebounds smoothly. Make any necessary adjustments based on your riding preferences.
Adjustment and Customization for Better Performance
The Edge R rear shock offers a range of adjustment options that allow you to fine-tune your ride. Understanding these adjustments will help you optimize your shock for different terrain types and personal preferences.
Air Pressure Adjustments
Adjusting the air pressure is the primary method for customizing the shock’s responsiveness. The air pressure should be set based on rider weight, style, and intended use. A lower pressure generally provides more comfort, while higher pressure is ideal for increased performance on rougher trails. Start with the manufacturer’s recommendation and adjust based on personal feedback.
Rebound Damping Adjustment
The Edge R includes a rebound damping feature that controls how quickly the shock returns to its original position after compression. A faster rebound is better for smoother trails, while slower rebound settings provide more control on aggressive terrains. Adjust the rebound damping by turning the knob on the shock body.
Compression Damping
The Edge R also allows you to adjust the compression damping to control how the shock reacts under load. By increasing compression damping, you can prevent the shock from bottoming out on bigger hits. Conversely, decreasing the compression damping makes the shock more sensitive, providing a smoother ride on smaller bumps.
Maintenance of the Edge R Rear Shock
To ensure the longevity and proper function of the Edge R rear shock, regular maintenance is crucial. Here are some tips for keeping the shock in top condition:
Cleaning and Inspection
Regularly clean the shock and surrounding areas to prevent dirt and debris buildup. Use a degreaser to remove grease, grime, and mud from the shock’s surface. Inspect the seals for any signs of wear or damage. Replace seals if necessary to prevent air leakage.
Lubrication
Apply a thin layer of grease to the shock’s mounting points and bushings to minimize friction and ensure smooth operation. Be sure to follow the manufacturer’s lubrication guidelines to avoid over-greasing.
Air Pressure Check
The air pressure in the Edge R rear shock should be checked periodically, particularly before long rides. Adjust the air pressure based on the conditions of your ride and any changes in temperature.
Annual Service
It is recommended to send the Edge R shock for a professional service at least once a year, depending on usage. This service includes oil replacement, seal checks, and internal adjustments, ensuring your shock performs like new.
Troubleshooting Common Set-Up Issues
While the Edge R rear shock is designed for ease of use, there are a few common issues that riders may encounter during setup. Here’s how to address them:
Shock Doesn’t Rebound Properly
If the shock isn’t rebounding as expected, check the rebound damping settings. If they are set too slow, the shock may not return to its original position quickly enough. Adjust the rebound to a faster setting and test again.
Shock Leaks Air
Air leakage is often caused by damaged seals or improper installation. Inspect the seals for cracks or wear and replace them if necessary. Additionally, ensure that the shock was installed correctly and that the air valve is properly sealed.
Bottoming Out
If the shock bottoms out during hard impacts, you may need to increase the air pressure or adjust the compression damping. Ensure that the shock’s air pressure is set according to your weight and riding style to avoid bottoming out on bigger hits.
Comparison with Similar Models
When considering a rear shock for mountain biking, it’s important to evaluate various models to find the best fit. Here’s how the SR Suntour Edge R compares with similar rear shocks from other brands.
Fox Float DPS vs. Edge R
The Fox Float DPS is a premium rear shock with adjustable damping settings, making it a highly customizable choice. However, it comes at a higher price point than the Edge R, which offers similar performance but at a more affordable price. Both shocks offer adjustable air pressure, rebound, and compression damping, but the Edge R offers excellent value for riders on a budget.
RockShox Deluxe Select+ vs. Edge R
The RockShox Deluxe Select [paid link]+ features a more sophisticated damper with a wider range of settings, but the Edge R offers easier and more intuitive adjustments. While the RockShox shock is more suitable for aggressive riders seeking fine-tuned suspension performance, the Edge R provides a more balanced option for riders who want reliable performance without the complexity.
Compatibility with Other Drivetrain Components
The SR Suntour Edge R rear shock is designed to work seamlessly with a wide range of mountain bike components. However, it’s essential to ensure compatibility with your bike’s frame and drivetrain components to maximize performance.
Frame Compatibility
The Edge R rear shock is compatible with most modern mountain bike frames that support eyelet mounts. Check your bike’s specifications for shock size and mount compatibility before installation.
Drivetrain Compatibility
While the Edge R is primarily a suspension component, it’s important to ensure that it pairs well with your bike’s drivetrain. If you have a high-performance drivetrain, like Shimano XTR or SRAM XX1, pairing it with the Edge R will offer a well-rounded riding experience, balancing suspension comfort with drivetrain efficiency.
The SR Suntour Edge R rear shock is a high-performance, adjustable suspension solution for mountain bikers who want a reliable and versatile [paid link] shock at an affordable price point. With its excellent adjustability, easy installation, and robust performance, the Edge R is an ideal choice for a wide range of riders, from weekend warriors to competitive athletes.
