Open Bath Cartridge and Adaptor Kit

Technology


 

 

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 optional 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 virtually maintenance free.

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 using coil conversion kits and when air progression is not enough to prevent bottoming

Optional FvAT/HSB System

Includes the 20 mm Cartridge Damper Kit Insert and fork cap adaptor.

Self install kit, user serviceable and revalvable.

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.


Talas 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.

ABS Option

Click here for more details


In order to make the overall spring rate as linear as possible we recommend the minimum or no ramp pressure.
We recommend that you may need to purchase the next stiffer spring for your weight because no addition spring rate will be generated by the ramp up system.
We prefer to control bottoming with the use of our optional ABS on the damper side.
This will create a more linear spring system without any mid to end stroke ramp-up and will improve deep square edged hits, better control on jump faces, it should be noted that rebound damping cannot properly compensate for progression in spring rate.

We are pleased to announce our new External Progression Adjustment System for Fox Forks. The Air and Hydraulic Ramp System.


Air RAMP System
RAMP (Remote Adjustable Modulated Progression)


Used to control the rate of progression of the Evol air spring system.
Compatible with Fox air forks with bleeder valves in lowers. Models include all 2021 models of the Fox 36, 38 and 40’s.
Mounts to the air bleeder hole and is clamped to the back of the lowers. Easy installation and adjustable with you air pump.
Provides external adjustment of air ramp up from progressive to more linear.
The secondary adjustment reduces pull down effect of the negative spring to increase ride height and provide more effective travel and also serves as air bleeder to release pressure build up in lowers.
Allows removal of tokens to provide a larger positive air chamber for a longer linear range of travel with a smoother external adjustable progression to resist bottoming.
Only one required for the stock damper.


Hydraulic RAMP System
RAMP (Remote Adjustable Modulated Progression)
Provides external adjustment of the effective oil height in our Open bath cartridge system.
Compatible option for our open bath damper system with all Fox forks with bleeder valves in lowers. Models include all 2021 models of the Fox 36, 38 and 40’s.
Mounts to the air bleeder hole and is clamped to the back of the damper side lowers. Easy installation and adjustable with you air pump
External adjustment of the air over oil ramp rate for added progression or a more linear feel.
Increased oil volume above cartridge to reduce aeration which improves damper performance.
The open bath cartridge allows for both sides to create ramp up, so two units can be installed.

Call for more info and to place order.
