    According to the excellent Craig Smith of Mendon Cycleworks USA KT004 is the tool I need. It will open up lefties from 2001 to about 2004, so not as niche as first thought.

    It's irritatingly expensive though.

    Options:

    i. Buy tool, suck it up.
    ii. Get a similar tool machined
    iii. Bin the poor dear and give up
    iv. Find someone with the tool and borrow it

    I don't like iii - I hate the idea of throwing away something like this, especially as the air spring is still obviously functional. I like the idea of getting something machined to do the job, but I have a suspicion I'd need two tools machined which will end up costing more than the KT004. I like the idea of borrowing the tool, but I tried this with the Castle Tool for Headshoks and had no joy - and that's a more useful tool as it opens up pretty much any Headshok from the year dot.

    Balls. Guess I'll have to pony up.
