    If anyone with a STD wants to measure the length of their air shaft......lmk
    Well doesn't that effectively prevent shortening travel via spacers? How would the pump method you described work in long-term usage?

    I'm a total suspension fork newbie trying to decide between 100mm and 120mm models...

    Dougal, do you have any thoughts on how to space it down to 100?

    I'm thinking 2 more spacers under air piston for a total of 5 would do it and increase negative volume.

    Thanks!
    Yes. Exactly that.

    For the lower spacers. You can add but not subtract.

    I'm talking about the bottom spacers. You change travel with the top spacers.
    What do you mean by "long term"? Worse case scenario is you have a attach the pump once in a while.

    Ummm....you are measuring the arch....which is a constant.
    The clearance issue ( or nonissue) is with the crown when compressed

    Yes, exactly, with the STD fork the crown can come below the arch so Manitou says you need 26 mm of clearance between the tire and the arch to avoid the crown hitting the tire at maximum compression. With the EXT fork which doesn't come below the arch as far you only need 6 mm clearance.

    You should still air down the fork and check clearance.

    Can you measure the diameter of the JJ 4.8, I'm curious if it's the same size as a Minion 4.8

    Manitou recommends for 4.8 inches tire, the EXT variant. No STD variant.


    The previous series of the fork has a mistake, Manitou fix the problem the fork for free.

    Here you can read it: Das Manitou Mastodon Update bringt den vollen Federweg zurück!

    The suspension fork does not use the entire spring travel. This is the mistake, Manitou repairs the free. All the new fork will no longer have the problem.

    The bottom-out bumper was too firm?

    You want the space between the tire and the crown.
    The space between the arch is always the same and never an issue.

    What air pressures are you guys running? I'm 185 and run 70psi in a 120 STD Pro and I'm not useing very much travel. Its way less than they recommend.

    I'm 165ish and run 47psi.
    Don't get hung up on the psi number....shock pump gauges ( or any cheap gauge) are not super accurate

    Finally managed to get a Mastodon delivered to the UK. Comp, EXT, 120mm. I'm keen to extend it to 140mm travel. Any of you early adopters opened up a Comp to adjust it? Have seen Manitou's service document for the Pro but can't find one for the Comp. I have the tools. Will just ride it at 120mm for now until I can find specific instructions for the Comp.

    No, but now I wish I had. I bought it from US ebay because I was in a hurry, but the Global Shipping Programme is a bit slow. I bought the Comp version which FaTbike24.de don't seem to have yet, but comparing prices on the Pro they are cheaper. Ho hum.

    Mind you, I wouldn't want to have missed all the fun of tracking it from Florida to Georgia, Kentucky, Paris, London, Warrington and Edinburgh. Now I know why they called it the Global Shipping Programme.

    Ha! Ha! designer forks with all those locations! according to an email I got from hotlines, they are available the end of June to order in the UK and will be £749 RRP for the Pro version so I'm going to hang fire ordering as they work out at £806 from Germany.....might be the first in the UK with them on a Farley EX.
