    Yes , I start to realise that... and the spring seems quite soft for the 70psi I pumped in.
    Fox does not specify the spring rate for that one in the doc.

    The quite soft spring rate for the negative spring was not so bad after all, especially after having removed the top out spring! I now have a good balance between the positive and negative springs at full extension which increased the initial suppleness to what you would expect from a modern fork.
    I also swap the fox float fluid for some gold oil in the positive chamber and crank up both compressions a little.
    Only drawback is that there is now a top out klonk but nothing I notice while riding tho...

    Looking for a bladder for the non-inverted RC2.
    Anyone around here still got one and would post them to Europe?

    I found mine on ebay and it was shipped from Germany.
    You will probably find the complete service kit easier than the bladder alone. References can be found earlier in this thread.

    Yeah, thanks. Found that as well in the mean time. I hoped, FarkinRyan still would have had one to give away, but having a complete kit won't hurt I guess.

    I have maximised my armchair engineering skills and replace the original negative spring of my old 36 with a cut XS Boxxer spring and a few other pieces in order to allow things to glide freely and rattlefree. Now the fork feels like the front tire is punctured... :panic:
    At least I got rid of the top out noise! :thumb:

    That's a little long for a negative spring eh?

    Actually a long and rather soft negative spring makes plenty of sense to me: it allows the force vs travel curves of the negative and positive springs to blend seamlessly while a shorter but stiffer negative spring will create a combined air spring curve with a kink where the negative spring is fully extended.

    130mm which is where I want it to be
    There were 50mm of spacers on top of the original negative spring before if you check the picture above

    How much positive contribution to the total weight of the fork does the negative spring have?

    your running a 180mm fork at 130mm of travel?


    a clearer picture is forming in my mind

    Can you please rephrase? I am not sure if I understand...

    More is not always better. ;)
    I have this fork on my hardtail where 180mm of travel would result in a unnecessary high bb and would be way too much anyway.
    I can also easily convert it back to its original shape if needed... No worry!
