Looking for a wise soul to give me the beta on oil level ranges in a Cannondale Fatty X Hewadshok; the nifty 25mm travel version found on slightly older XS 800's. Any info at all would be appreciated.

...um, didn't think that you were 'supposed to have any air in the system. Air in the system means free play at the end or start of stroke.

air = bad

I replaced mine with a carbon fork and am much happier.
(cant get a replacement shaft in OZ with out spending oo much $)

That was the issue. An o-ring split, all the oil leaked out, and the damper (and thus rebound) was non-existent. Know I believe the problem is all sorted out.

I am curious about your fork replacement. The Fatty X adds axle-crown height quite a bit beyond most cross forks (I think 420mm versus 390 or so?). Did you find a taller fork, did the headset adapter add height, or did you just let the headtube steepen? Just wondering...:confused:

I got an adaptor turned up.

Rather than remove the Cannondale SI cups, used the original bearings top and bottom and had a longish adaptor made to fit the bearing to axle length.

For the top half, I used a tapered plastic ring from a used diacompe headset and had a matching taper alu spacer turned with a flange ( to stop it 'falling' into the head tube)

now run a regular 1 1/8 aheadstem stem.

works well, looks a little odd, but lpane to spray or ano the silver lower spacer.

plus the adaptor has a built in cable stop
