RockShox Reverb Seatpost Parts Brass Keys - Pack of 3

The RockShox Brass Keys are essential service parts designed to restore smooth, play-free movement in your Reverb or Reverb Stealth seatpost. These keys help maintain precise post alignment and prevent side-to-side wobble over time.

Sized for Multiple Reverb Models: Available in sizes 0, 3, 4, 5 and 6, these brass keys are compatible with Reverb and Reverb Stealth A1–B1 models, as well as the latest Reverb AXS (2020+). Choose the correct size to match your post and restore optimal performance.

Engineered for a Precision Fit: Brass keys are critical wear components that fit between the inner and outer tubes of the seatpost. Worn or damaged keys can lead to play in the post—replacing them ensures tighter tolerances and smoother action on every drop and return.

Compatible with Reverb Remote Variants: These keys are suitable for posts with both silver (A1) and black (A2) remote adjuster knobs, offering wide compatibility across generations. Pair them with other service parts like the hydraulic tubing kit for a full refresh.

Keep your dropper performing like new with these genuine RockShox replacement brass keys. They're a small investment that delivers noticeable improvement in seatpost function and durability.
