RockShox DebonAir Air Spring Assembly

This specific assembly is designed exclusively for the RockShox Psylo Silver (A1+) model from 2025 and newer. Always verify your fork's specific model year and chassis type before purchasing, as internal components are rarely cross-compatible between different fork generations.

This assembly is configured for a 140mm travel length. If your current fork is set to a different travel, installing this part will change your fork's travel to 140mm, which may affect your bike's geometry and handling.

If you are comfortable performing basic suspension service, such as lower leg removal and air spring replacement, this is a manageable task. However, it requires specific tools like a cassette tool or socket for the top cap and internal snap ring pliers, so ensure you have the proper service manual and tools on hand before starting.

You should consider replacing the assembly if you notice your fork feels harsh, has excessive stiction, or fails to hold air pressure despite servicing the seals. It is also a smart upgrade if you are performing a full overhaul and want to ensure your spring rate remains consistent throughout the entire stroke.

Yes, this assembly is compatible with both 27.5-inch and 29-inch wheel sizes for the Psylo Silver A1+ platform. The internal air spring design is standardized across these wheel sizes for this specific fork model.
