bought a crank bros joplin second hand and in the last week it has started to creep down from full extension by about 3/4 inch, ive adjusted the collar and tried a few tips but these haven't solved it, i presume it needs a service or is it a more serious problem?

    Have you tried the tip where you hold the unit upside down and then cycle the mechanism a few times to sort the internal pressure equilisation thingy?

    Sometimes this sorts, otherwise a trip back to 2Pure perhaps....

    Does it have the correct psi in the chamber? 75psi IIRC
    This might help

    This is clearer and it's the same post just re-labelled as a Joplin when CB bought the rights:
