Marzocchi 380 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.
