Fox 36 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
(uses stock Fox 36 rebound Fork Cap).

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.

Push ACS3 coil conversion kits
Push ACS3 coil conversion kits are compatible with our cartridge.
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 and better control on jump faces.

The Avalanche Advantage over the the Fit RC2 cartridge:

 

A larger (20mm vs 15.5mm) 4 port rebound valve that has more low to midspeed transition control and optional high speed shim configurations for different spring rates and rider conditions.

A midvalve with user tunable shims/valving that provides anti-dive feature while still blowing off without low speed harshness on small bumps.

The same DHF proven design (20 mm) 4 port compression valve with optional revalving charts and shims available to fine tune your fork for your individual riding conditions and ability.

User serviceable, all parts are available here at Avalanche to service or modify the internal set-up.

Revalving kits can be purchased from Avalanche or any suspension tuning shop that carries standard 6 mm shims.

High speed adjustment is at best a compromise of the original shim stack, depending on the high speed spring preload adjuster rate and where the pressure is applied

on the shim stacks you can get less than desirable results in damping feel, i.e. preloading the outside rim of the shim may make the high speed stiffer,

but also creates mid and low speed harshness in the damper.

The original RC/RC2 large compression adjuster protrusion at the bottom of the fork is eliminated and cleanly redesigned.
