How does the VSS for RockShox BoXXer differ from a standard air token?

A standard air token adds fixed volume reduction, increasing ramp-up uniformly regardless of impact speed. The VSS for RockShox BoXXer reacts dynamically to shaft speed and pressure: it behaves like 1–2 tokens during slow compressions and builds to 3–6 tokens at race pace, with the DH/Race+ profile reaching up to ~8 tokens only during fast, high-energy impacts. This means the fork stays supple during normal riding without sacrificing support under hard hits.

Which RockShox BoXXer configurations is the VSS compatible with?

The VSS fits RockShox BoXXer forks running Solo Air, DebonAir, and DebonAir+ air springs, including 35mm and 38mm 2024+ models. It works with or without ButterCups installed. It is not compatible with Lyrik, ZEB, 32mm forks, Gold/Silver models, or Dual Position air spring systems.

Do I need the VSS Configuration Tool before purchasing the VSS for RockShox BoXXer?

Yes — using the VSS Configuration Tool before ordering is required. BoXXer forks run significantly higher pressures than most trail forks, especially 2024+ models, which changes airflow behavior. The correct nozzle size is critical to performance; the wrong size will meaningfully affect how the token reacts. The tool determines which nozzle suits your specific fork pressure and setup.

What is included with the VSS for RockShox BoXXer and what does it cost in Canada?

The VSS for RockShox BoXXer is priced at CAD $79.49 and is in stock for Canadian customers at Shockwave Parts (shockwaveparts.com). Each order includes one VSS Smart Air Token in your chosen support profile (Race or DH/Race+), your selected nozzle, one nozzle one step softer, one nozzle one step firmer, and a nozzle wrench.

Does the VSS for RockShox BoXXer require ongoing maintenance or pressure adjustments?

No maintenance is required. The VSS is 100% plastic with no moving parts, so there is nothing to service or replace over time. Pressure adjustment is usually unnecessary after installation, though some riders drop air pressure slightly to improve grip — the token's adaptive response compensates for the change in ramp-up behavior.

Adaptive Air Token for RockShox Boxxer

Patent Pending Technology

Compatible with RockShox Boxxer (Solo Air, DebonAir, DebonAir+), including 35mm and 38mm (2024+) models. Works with or without ButterCups. The VSS token is also compatible with RockShox ZEB and Lyrik forks when equipped with the correct nozzle. Not compatible with 32mm forks, Gold/Silver models, or Dual Position air springs.

Built for speed. Built for impact. Full control when it actually matters.

This version is specifically tuned for Boxxer. It delivers strong adaptive support while keeping the fork usable and controlled in all conditions.

More Control Stay higher in travel

Extreme Adaptive Support 1 to 8+ tokens on demand

Zero Maintenance 100% plastic, no moving parts

VSS Configuration Tool (Required)

Boxxer forks typically run much higher pressures than ZEB or Lyrik forks. Use the VSS Configuration Tool to determine the correct nozzle for your setup.

Using the wrong nozzle size can significantly affect performance.

Choose Your Setup

Support Profile (Required)

Standard: Strong support up to approximately 6 tokens. Best for most riders and tracks.
DH / Race+: Can reach up to approximately 8 tokens during rare high-speed impacts while remaining controlled and compliant during normal riding.

Nozzle Size (Required)

BoXXer forks operate at significantly higher air pressures than most single-crown forks, making proper nozzle selection critical for optimal performance.

Important: The DH / Race+ version is not harsh all the time. It only ramps up aggressively during very fast, high-energy impacts.

What's Included

1× VSS Smart Air Token (selected support profile)
Your selected nozzle
+1 softer nozzle
-1 firmer nozzle
Nozzle wrench

Pro tip: High-pressure setups typically require larger nozzle sizes.

How It Works

Virtual volume, not physical volume. The VSS reacts to shaft speed and pressure conditions rather than acting like a traditional volume spacer.

Slow sections: Feels similar to 1–2 volume tokens.
Race pace: Builds strong mid-stroke support equivalent to roughly 3–6 tokens.
Extreme impacts: The DH / Race+ profile can reach the equivalent of approximately 8 tokens.

Designed to absorb high-speed compressions without making the fork harsh or unpredictable.

Compatibility Details

Fits: RockShox Boxxer, ZEB, and Lyrik
BoXXer models: 35mm and 38mm (2024+)
Air springs: Solo Air, DebonAir, DebonAir+
ButterCups: Fully compatible
Not compatible: 32mm forks, Gold/Silver models, or Dual Position air springs

Important: The VSS token itself is interchangeable between compatible forks. However, each platform requires its own nozzle size because operating pressures differ. BoXXer forks generally require larger nozzles than ZEB or Lyrik forks. If you plan to move your VSS between forks, install the correct nozzle for each one. Additional nozzles are available separately, or contact us for recommendations.

Common Questions

Q: Do I really need the Configuration Tool?
A: Yes. Proper nozzle sizing is essential for achieving the intended performance.

Q: Can I use this VSS in my ZEB or Lyrik?
A: Yes. The VSS token is fully compatible with Boxxer, ZEB, and Lyrik forks. Only the nozzle changes between platforms.

Q: Why does BoXXer use different nozzle sizes?
A: BoXXer forks typically run much higher air pressures than ZEB or Lyrik forks. Higher pressures require different airflow characteristics, which is why nozzle sizes are different.

Q: Can I swap the VSS between different forks?
A: Absolutely. Simply install the correct nozzle for the fork you're using. If you need another nozzle, you can order one separately or contact us for the correct recommendation.

Q: Does it require maintenance?
A: No. It's made entirely from engineered plastic with no moving parts. A conservative lifespan is 2–3 years, although it will typically last much longer.

Q: Do I need to change my air pressure?
A: Usually not. Some riders choose to lower pressure slightly for additional grip, but most setups work with your existing pressure.

Q: Is this just another volume token?
A: No. Unlike a traditional token that permanently reduces air volume, the VSS dynamically adapts its effect based on shaft speed and impact intensity.

About the nozzles: The VSS token is the same across compatible RockShox forks. What changes is the nozzle. Because BoXXer operates at much higher air pressures than ZEB or Lyrik, it typically requires larger nozzle sizes. Always use the recommended nozzle for the fork you're riding.
