FAQs

Does this post come with a bleed kit?

Yes, standard Rock Shox Reverb units usually include a bleed kit to maintain the hydraulic remote.

Can I install this on a bike without internal routing?

No, the Reverb Stealth is specifically designed for internal cable routing only.

How often should I use the Vent Valve?

Only use the Vent Valve when you notice the post has a 'squishy' feeling caused by air trapped in the hydraulic system.

What is the diameter of this specific model?

This model is specifically 30.9mm.

Can I adjust the return speed?

Yes, there is a speed adjuster dial on the remote that allows you to control how fast the saddle returns.

What fluid does the Reverb use?

It uses Maxima Fluid, which is formulated to reduce friction and improve performance.

Troubleshooting

The seatpost has a springy, squishy feel when seated.

Use the Vent Valve feature to bleed air out of the system following the official Rock Shox maintenance guide.

The post returns slowly even after a full bleed.

Check the internal air pressure (if applicable) and ensure the return speed adjustment knob on the remote is fully open.

The remote button is hard to press.

Check for kinks in the hydraulic line or excessive bends in the cable routing inside the frame.

Pros and Cons

Pros

  • Significantly easier to actuate than older models
  • Vent Valve makes maintenance simple and fast
  • Faster return speed improves ride flow
  • Shorter total post length fits more frame geometries

Cons

  • Requires frame compatibility for internal cable routing
  • Plunger remote can be less ergonomic than lever-style alternatives
  • Requires specific maintenance intervals to keep performance optimal

Setup, Compatibility & Care

Installation of the Reverb Stealth requires a frame with internal routing ports. Because this model uses a hydraulic remote system, ensure your cable routing path has minimal sharp bends to maintain system pressure.

  1. Measure your seat tube depth to ensure the post will fit fully into your frame.
  2. Route the hydraulic line through your frame according to your manufacturer's instructions.
  3. Bleed the hydraulic system if the remote feels spongy or unresponsive.

For care, wipe the stanchion clean after every ride to prevent dirt ingestion. If the post begins to feel like it has "squish" or play, utilize the Vent Valve by following the manufacturer's specific procedure to purge excess air from the system. Always ensure the post is torqued to your frame's specification to avoid damaging the seatpost or the frame.
