Our CO3 cartridge is an open cartridge 3-way adjustable. We have developed a unique compression block using a single knob. In position "pushed" you adjust
the low speed compression 24 clicks. In position "fired" Now adjust the high speed of 24 clicks too. The adjustment range is very wide, you necessarily get the perfect setup for
you. On the top caps, you find the low speed rebound adjuster knob to 24 clicks. The high speed trigger is managed by a stack of internal valves. Our CO3 cartridge is completely
designed and manufactured in our workshops with our CNC machines.
