Öhlins TTX Air Bleed Elbow

• This tool is designed specifically for the Öhlins TTX Air.
• Unlike the TTX Coil version, this tool does not install over a plastic outer sleeve.
• The TTX Air uses a bladder system and does not use an IFP.
• A dedicated M4 bleed fitting is not currently available.
• Some brake bleed fittings may be compatible with the M4 bleed port, but this has not yet been fully tested.

The Öhlins TTX Air can be difficult to hand bleed because the shock must remain completely full of oil throughout assembly. Unlike many monotube shocks, the TTX Air uses a bladder rather than an IFP, so there is no final IFP depth adjustment available after assembly.

This elbow creates a raised oil reservoir above the shock while it remains horizontal, allowing the damper to stay completely full during the hand bleed process. It also provides additional oil volume for pushing oil through the entire damper using the standard rubber glove technique.

The additional oil volume can help remove trapped air before the bladder is installed, simplifying the bleeding process for home mechanics.

For users performing a full rebuild, this tool can reduce the need for specialized vacuum bleeding equipment and make DIY servicing more accessible.

Unlike many monotube shocks, the Öhlins TTX Air uses a bladder instead of an IFP. Because there is no final IFP depth adjustment available, final assembly must be performed with the shock already properly bled.

1. Fill the shock and elbow with oil.
2. Perform the rubber glove bleed technique while cycling the adjusters and damper.
3. Continue until air bubbles are no longer visible.
4. Install the bladder while attempting to displace as much remaining air as possible.
5. Remove excess oil from the elbow and allow any remaining trapped air to migrate upward.
6. Install the seal head carefully, ensuring that no air is introduced during final assembly.
7. Because there is no IFP depth adjustment available afterward, take extra care during final assembly to ensure all visible air has been removed before closing the shock.

Professional servicing of an Öhlins TTX Air can easily exceed several hundred dollars. This tool was developed to provide home mechanics with a practical alternative.

Most of the shock can be serviced using common workshop tools. The bleeding process is typically the most difficult part, and this elbow was designed specifically to simplify that step.

Development of a dedicated M4 bleed fitting and additional TTX service tools is ongoing, but this bleed elbow already makes DIY rebuilds significantly more accessible.

As with any suspension service, proceed carefully and at your own discretion.
