Fork cap and Rebound Adjuster
Update 5/25/10:
Each cartridge kit can be installed in different forks with the optional adaptor kit which includes the fork cap, ABS adaptor, spring seat, and lower casting nut adaptor specific for that fork. Current plans include kits for most of todays 8 inch travel forks, i.e. the 888, Kowa, Fox40. The internals are removed from the fork and replaced with our AVA Advantage Cartridge Kit similar to the DHF forks . Kit consists of speed sensitive revalveable open bath damper (army green), base valve compression bolt adaptor (light green and light blue), ABS system and slider tube adaptor ring (green and gray), Fork cap and rebound adjustment system (yellow) .
In most cases the left fork leg will not require any modifications, World Cup air and single spring forks. For older dual spring forks the kit will use your existing springs and preload collars and additional preload adjustment spacers will be provided . Single or dual damper kits can be purchased, in most cases a single damper is all that is needed, the other leg will be used a dummy leg for the spring and preload only. Optional tune kit will include instructions, valving shims and valving componets for setting up the fork for any condition or rider ability. Optional adjuster knob kit can be purchased if knobs are your style, otherwise set them and forget them with a standard screwdriver.
