Installation of the Super Deluxe Ultimate RC2T
Mounting the Shock
- Prepare the Shock: Before installation, ensure that your shock is fully assembled and in proper working condition. Verify that the eyelet or the hardware is compatible with your bike frame.
- Align the Shock with the Frame: Position the shock in the rear triangle of the bike frame. Pay attention to the orientation of the shock, as the air valve should face outward for easy access.
- Install the Mounting Hardware: Insert the bolts through the shock’s mounting eyes and the corresponding holes in the frame. Tighten the bolts with a 6mm Allen wrench [paid link] to the torque specifications provided by RockShox (typically 10-15 Nm). Always ensure that the bolts are properly torqued to avoid any movement or looseness.
Attaching the Air Canister
- Add Suspension Fluid: Before attaching the air canister, check if the shock requires suspension fluid in the air chamber. Add the recommended type of fluid as per the RockShox specifications.
- Install the Air Canister: Align the air canister with the shock body and carefully tighten it. Use a 20mm socket and ensure that it is torqued to the manufacturer’s recommended values.
- Check for Leaks: After installation, inspect the shock for any air leaks. You can do this by using soapy water around the seals and watching for bubbles.
Adjustment and Fine-Tuning
Adjusting the Rebound and Compression
- Rebound Adjustment: The Super Deluxe Ultimate RC2T comes with an easy-to-use rebound adjustment knob. Turn the knob clockwise to slow down the rebound and counterclockwise to speed it up. Start with the rebound setting at the midpoint, then fine-tune based on your riding style and terrain.
- Compression Adjustment: The RC2T shock has two compression settings: low-speed and high-speed compression. To adjust, use the provided knobs:
- Low-Speed Compression: This controls how the shock behaves during slower movements, such as climbing or pedaling. Turn it clockwise to increase compression for more support or counterclockwise for a more plush feel.
- High-Speed Compression: This controls the shock’s performance during high-impact events, such as landings or rough descents. Adjust it similarly to the low-speed knob but with a focus on improving control during aggressive riding.
Setting the Sag
Proper sag is essential for ensuring that the shock performs optimally. For the Super Deluxe Ultimate RC2T, start by inflating the shock to the recommended pressure (usually indicated on the shock body). Then, sit on your bike in full riding gear, allowing your weight to compress the shock. Ideally, the sag should be around 30% of the shock’s total travel. Adjust the air pressure as needed to achieve this.
Maintenance to Extend Lifespan
Regular Cleaning
Cleaning your Super Deluxe Ultimate RC2T after every ride is crucial to prevent dirt and debris from building up on the seals and other moving parts. Use a clean cloth and isopropyl alcohol to wipe down the shock body. Pay close attention to the seals, as dirt can cause premature wear.
Seals and O-Rings
Regularly inspect the shock’s seals and o-rings. These parts wear out over time and need to be replaced to prevent air leakage and performance issues. If you notice oil around the shock body or air loss, it’s a sign that seals or o-rings may need replacing. Always use RockShox replacement parts for optimal performance.
Suspension Fluid Change
Over time, suspension fluid in your shock can break down, which reduces damping performance. It’s recommended to change the fluid every 50-100 hours of riding, depending on your usage. To do this, remove the air canister, drain the old fluid, and refill with fresh suspension oil. Be sure to use the correct type of fluid as specified by RockShox.
Troubleshooting Common Issues
Loss of Air Pressure
If you notice a loss of air pressure, check for leaks around the air valve and seals. You can use soapy water to identify small leaks. If the leak is not obvious, try removing the air canister and reapplying lubrication to the seals before reattaching it. If the problem persists, the seals or o-rings may need replacing.
Excessive Rebound or Compression
If the rebound feels too fast or too slow, or the compression adjustment doesn’t seem to work effectively, it may be due to incorrect fluid levels or internal damage. Check the fluid level and replace it if necessary. If the problem persists, consult a professional mechanic for internal service.
Sticking or Binding
If the shock feels stiff or binding during operation, it may be due to dirt or debris in the shock body. Perform a thorough cleaning, paying special attention to the seals and shafts. If the problem is not resolved by cleaning, the internal components may need to be serviced.
Customization and Optimization
Fine-Tuning for Your Riding Style
To optimize the performance of your Super Deluxe Ultimate RC2T, you’ll need to fine-tune it based on your specific riding style and the type of terrain you ride on. For cross-country riding, consider running lower air pressure and softer compression settings for maximum comfort. For aggressive downhill or enduro riding, increase the air pressure, tighten the compression, and adjust the rebound for quicker recovery.
Upgrade Your Damper
The Super Deluxe Ultimate RC2T offers high-end performance, but you can further improve it by upgrading to a custom damper setup. This can provide better fine-tuning options and improved damping control, especially for more advanced riders.
Adjusting for Different Terrain Types
For riders who frequently switch between terrain types, the RC2T offers flexibility in fine-tuning compression and rebound settings. For example, reduce high-speed compression and add more low-speed compression for smoother control on rough terrain, and increase high-speed compression when riding over smoother but technical tracks.
Comparison with Similar Models
While the Super Deluxe Ultimate RC2T is known for its advanced features and smooth performance, it’s worth comparing with other RockShox models, such as the Deluxe Ultimate and the Monarch Plus. The Super Deluxe Ultimate RC2T offers superior adjustment options with its dual compression system and is ideal for riders looking for a highly customizable ride. However, if you prioritize a simpler shock without as many fine-tuning adjustments, the Deluxe Ultimate might be a more cost-effective choice. For those looking for an even more rugged option for heavy-duty use, the Monarch Plus may offer more durability, but at the expense of a heavier weight.
Compatibility with Other Drivetrain Components
When installing the Super Deluxe Ultimate RC2T, it’s essential to consider the compatibility with your bike’s other drivetrain components. Make sure that your bike’s rear triangle and shock mounting points are designed to accommodate this shock. Additionally, the shock should pair well with a modern drivetrain system to ensure a smooth overall riding experience. If you are using an older model of bike, it may require an adapter to fit the shock.
By understanding how to properly maintain, adjust, and troubleshoot your RockShox Super Deluxe Ultimate RC2T, you can maximize its lifespan and enjoy top-tier performance on your rides. Keep your shock in optimal condition, and it will reward you with smooth, responsive rides on every trail.
