Hi all,

I have a mid 90's Cannondale F700 with a Fatty D Headshok. It needs a service, I know they're fiddly but does anyone have an exploded assembly drawing of the fork setup? The top bolt is seized in, so I've drilled it out, taken the lockout (black plastic cap) off, and there is hex hut with just a plain inner (no thread) so I'm a bit confused as to how turning the top cap to change from lockout to suspension mode actually works, unless the hex nut is a tight press fit on the shaft inside it?

As when the black cap is twiested, which twists the hex nut beneath, there is nothing gripping the shaft the the hex nut sits over? I was expecting it to be threaded...!

Anay help is appreciated.

I worked in a Cannondale dealership for a few years, although i never serviced the forks i recall that you had to have a few specialist tools - amoungst others is a 'crown tool' or something like that, it looked like a castle on a chess piece - however there is a great guy in Exeter that services them cheap.

Keep an eye on the classifieds today, my pal just had a frame fail and is going to advertize a perfectly functional lefty fork and wheel today if you fancied an upgrade..

This may help if you still need to do it.

or this

If you got someone else to do it or managed to get a castle tool please let me know where from.

NB- Anyone know where I can get a Magura CCS to put in mine?

That would be Tony Nunn, well recommended if you don't fancy DIY:

There's nothing stopping you from ordering the correct tools from a Cannondale dealer, or at least there isn't in Canada.
