Had a cannondale super V800 (2000 model i think) for a while now and been running it with some nice magura rim hydraulics. A few months back a friend split one of his bikes down an did me a good deal on his wheels and hope disk brakes. Only problem being my forks have no disk mounts (the frame does but not forks??cannondale logic??) Bin watching out for some forks going on ebay with disk mounts (just to mention being a Cannondale its the 1.5inch headset) and have had no luck, i refuse to pay 300 for some new ones so decided to go for some 1 1/8 forks and get a reducer for the frame. Having bought some new forks I now need to remove the old fatty D headshox, so the question is how to go about it? To be honest i havent fully investigated them but being fatty D's they have the lockout at the top of the steerer so not the usuall star nut/headlock system that im familiar with.

Just wondering if anyone has any tips or tricks or even a vague idea of how to go about it?
thanks
