Rockshox Pike Open Bath Cartridge and Adaptor Kit



The best performance modification you will ever do to your fork!

Complete replacement of the damper with our open bath cartridge!

This will make your fork feel like a completely different fork, because it is!

Low speed damping that’s firm but still blows-off to be plush on small bumps,
Reduced fork dive that eases the fork through the travel without harshness,
No more high speed compression spikes and no more bottoming with the ABS system.
Low speed compression and rebound adjusters help fine tune the valving as to how it transitions from
low to mid and when the high speed kicks in,
Much more effective than the other dampers attempt to add high speed adjustment without the proper shim stack.


Open Bath Cartridge system for better lubrication, smoother action and low maintenance.

External low speed compression and low speed rebound adjusters

Internal revalvable custom high speed compression and rebound valving.

Internal Anti-dive MidValving.

Optional ABS when air ramp-up is not enough to prevent bottoming

Includes the 20 mm Cartridge Damper Kit Insert, adaptors and fork rebound cap.

Self install kit, user serviceable and revalvable

ABS not recommended for smaller travel set-ups of 150-120 mm

All cartridges are optimized for current travel.
If you plan on changing the travel in the future, please let us know so the proper cartridge tube can be installed.

Adjustable travel positions are still functional as only the damper side is modified.
It will work in all travel modes, the tune can be set for a best compromise between
the two or we can set it up for the higher travel mode, because this is the more sensitive position generally used for DH. When set to the reduced travel mode we suggest that you stiffen the suspension up with the clickers, same as you did with the stock damper.

Available for all models including 26, 27.5, 27.5+and 29 and boost models
(solo air and dual position adjust)
(RCT3 and RC)

Are your cartridge dampers for the pike and Lyrik interchangeable? I have a pike now, but may upgrade to Lyrik in the future. Also are you offering a upgrade to the existing charger damper as well as a complete open bath replacement?

The length and fork cap threads for the stock cartridges are different so we have to make them unique for each fork. We used to offer an upgrade for the charger damper but due to the amount of warranty issues with the internal components it became impossible for us to continue offering this tune.

We do not offer this service, sorry too many issues with the stock charger damper that we would have to assume responsibility for when doing the rebuild. In other words the rebuild parts and design of the damper are not good enough for us to service the damper to our standards.

I am currently running 3 tokens and the compression 3 from all the way soft, the fork still feels dives and is harsh on square edged bumps, does the open bath cartridge improve this set-up?
Yes, you will be able to run firmer low speed compression with less dive and a plush small bump feel. The midvalves will prevent low speed dive and the added compression will make the fork ride higher in the stroke. The high speed hits will not be harsh and the overall increase in compression throughout the stroke will prevent bottoming. This will allow you to remove all the tokens in the 160 mm set-up and have a more linear feel making the midstroke less abrupt for square edged hits.

How much different is the performance of your damper with the FvAT/HSV system versus without?

The FvAT HSB system allows us to setup the valving firmer and still blow-off on square edged bumps. The damper cartridge can be set up to be firm also but some compromise in the valving must be made and these firmer shims may not open as easily on square edged bumps. If you are looking for a plush overall feel then the HSB is not needed because the shims will be softer and will bend open on square edged bumps anyway.
