RockShox SID DebonAir Spring Shaft

This specific air shaft is designed exclusively for the RockShox SID C1 model. Please verify your fork's specific model year and chassis generation before purchasing, as internal components are not universally interchangeable across all SID versions.

While this shaft is designed for a 110mm travel setting, changing your fork's travel often requires more than just swapping the shaft. You should consult the RockShox service manual for your specific fork to ensure the damper and other internal components are compatible with the new travel length.

Yes, this is an original equipment manufacturer (OEM) replacement part from RockShox. It is engineered to meet the exact factory specifications for durability and performance, ensuring it integrates seamlessly with your existing suspension system.

Yes, performing a service on a suspension fork requires specific tools, including a cassette tool or socket for the top cap, a rubber mallet, and high-quality suspension grease. We recommend having the official RockShox service guide on hand to ensure proper torque specs and seal lubrication.

You typically replace the air shaft if the original has become scratched, bent, or if the internal seal head has worn out and is causing air migration between the positive and negative chambers. Replacing it restores the fork's original plushness and prevents the suspension from 'sucking down' or losing travel.
