The RockShox SID Select+ is a standout suspension fork tailored for cross-country and light trail riders seeking the perfect balance between weight, stiffness, and control. Packed with advanced technology, including the Charger RL damper and DebonAir spring, the SID Select+ delivers high-performance characteristics in a reliable package. This guide breaks down everything riders need to know about installation, adjustment, maintenance, troubleshooting, compatibility, and performance optimization of the SID Select+.
Tools Required
- 6mm and 5mm hex wrenches
- Torque wrench [paid link] (adjustable in Nm)
- Suspension pump
- Cassette lockring tool [paid link] (for crown race removal)
- Crown race setting tool
- Shock oil and RockShox dynamic seal grease
- Clean rags and isopropyl alcohol
Installation Procedure
Installing the SID Select+ fork involves careful preparation and precision. Begin by cutting the steerer tube to the appropriate length for your frame and headset stack height. Always leave enough steerer tube above the stem to accommodate spacers and future adjustments. After cutting, file the steerer tube to remove burrs.
Install the star nut using a proper setting tool, ensuring it’s driven to the correct depth. Fit the crown race onto the fork crown, then slide the fork into the head tube with the appropriate headset parts in place. Torque the stem and headset spacers to the manufacturer’s recommended values. Ensure the fork rotates smoothly without play.
Brake installation involves attaching a post-mount caliper, adjusting it for rotor alignment, and torquing the bolts securely. Lastly, install the front wheel, ensuring the thru-axle is tightened according to spec.
Initial Suspension Setup
Setting up the SID Select+ begins with air pressure adjustment in the DebonAir spring. Use a suspension pump to inflate to the recommended psi based on rider weight—this information is provided by RockShox in a setup chart.
Rebound damping is adjusted at the bottom of the right leg. Turn the red knob clockwise for slower rebound or counter-clockwise for faster rebound. Fine-tuning rebound based on riding style and terrain enhances comfort and control.
The Charger RL damper features a low-speed compression lever on top of the right leg. Riders can toggle between open and lockout modes, ideal for climbs or sprints. Adjust compression sensitivity as needed to match trail conditions.
Maintenance Best Practices
Routine maintenance is crucial to ensure longevity and optimal performance. After every 25 hours of riding, clean the fork stanchions and inspect the seals for dirt or oil. Apply a small amount of suspension-specific lubricant to maintain seal flexibility.
Lower leg service should be performed every 50 hours. This involves removing the lower legs, cleaning internal surfaces, replacing foam rings, and refreshing the fork oil. Use only RockShox-recommended lubricants and follow precise oil volume guidelines.
A full damper and air spring service is advised every 100 hours. This includes bleeding the Charger RL damper and disassembling the DebonAir air spring for inspection and lubrication. Always reassemble using torque specifications and dynamic seal grease.
Troubleshooting Common Setup Issues
If the SID Select+ feels harsh or unresponsive, check air pressure and ensure it matches your rider weight. Too low pressure leads to excessive sag, while too high creates a stiff ride.
For inconsistent rebound or compression response, inspect the damper knob settings and ensure internal oil levels are correct. A slow return after compression often points to insufficient rebound adjustment or air spring contamination.
Noise from the fork—like squelching or knocking—may indicate air/oil mixing or a need for lower leg service. Perform an inspection and service to address internal wear or contamination.
Customization and Performance Tuning
Riders can customize the SID Select+ by adding volume spacers inside the DebonAir spring. This increases progression and support during hard impacts, ideal for aggressive riding or heavier riders.
For weight savings and precision, consider upgrading to a carbon steerer tube or titanium bolts. However, maintain compatibility and torque guidelines.
Swapping out the standard Maxima Plush oil for custom-tuned viscosities can alter damping characteristics. Consult with a suspension tuning specialist to achieve optimal feel for specific terrain or race conditions.
Compatibility with Drivetrain and Frame Standards
The SID Select+ uses a 44mm or 51mm offset, which must match the frame’s geometry to maintain handling characteristics. It supports Boost hub spacing (15x110mm) for modern trail and XC bikes, improving wheel stiffness and tire clearance.
Brake mounts are post-mount, supporting rotors from 160mm to 180mm without adapters. Ensure brake calipers align properly to avoid rotor rub.
It features a tapered steerer tube (1.5” to 1-1/8”) and requires a matching headset. The fork’s axle-to-crown height is optimized for 100mm–120mm travel bikes, so confirm frame compatibility before installation.
Comparison with Similar Models
Compared to the RockShox SID Ultimate, the SID Select+ trades minimal weight savings for a more budget-conscious build while retaining the same damper and spring technologies. Riders who don’t require carbon components may find the Select+ offers superior value.
Against the Fox 34 Step-Cast, the SID Select+ is lighter and more responsive for pure XC use, though the Fox may appeal more to trail riders seeking extra stiffness.
The SID Select (non-plus) lacks the Charger RL damper and offers less sophisticated rebound control, making the Select+ a clear upgrade for racers and performance-focused riders.
Frequently Asked Questions
Is the SID Select+ good for aggressive trail riding?
The SID Select+ is best suited for cross-country and light trail use. It offers excellent stiffness and control, but heavier riders or those tackling rougher terrain may benefit from a burlier fork.
Can I use the SID Select+ with 2.4-inch tires?
Yes, it supports up to 2.4-inch wide tires with Boost spacing, offering ample clearance for most modern XC tires.
How often should I service the SID Select+?
Lower leg service is recommended every 50 hours, with full damper and spring servicing every 100 hours for optimal performance.
Is the Charger RL damper adjustable?
Yes, it features adjustable low-speed compression and rebound settings to fine-tune your suspension behavior.
Can I install the SID Select+ myself?
Installation requires specialized tools and precision. While skilled home mechanics can perform the task, professional setup is recommended for safety and performance.
What’s the difference between SID Select and SID Select+?
The SID Select+ includes the premium Charger RL damper and DebonAir spring, offering better damping and small bump compliance compared to the base model.
Conclusion
The RockShox SID Select+ stands as a premium choice for riders seeking lightweight efficiency with reliable performance. With its advanced damper technology, tuneable air spring, and trail-optimized stiffness, it delivers race-ready performance without sacrificing comfort. Whether you’re a dedicated racer or weekend warrior, the SID Select+ offers exceptional value, tunability, and confidence-inspiring control on the trail.
