you'll need a park rt-1 or similar, to knock the cups out of the headtube. You'll also need a press, like the park hhp-2. With the help of a friend and home depot, i made a "Park FU-2" out of some all-thread, washers, bolts, and weird copper plumbing fittings. Saved alot of money, that way.

You need to special tools to remove and install the cups and crown race. You can probably install the cups without special tools but for everythng else you need the right tools or hire someone that has them.

Here are the tools needed and their Park Tool numbers.
RT-1 Head Cup remover
CRP-1 Universal Crown Race Puller
HHP-3 Home Mechanic Bearing Cup Press (There also is a pro Cup Press.)
CRS-1 Crown Race Setting System
HMR-2 Shop Hammer (Just joking, you can any hammer.)

My "Park FU-2" is made of 2 blockes of wood, a bolt, a few nuts and washers (cut and fender). In addition to this press I use a bar clamp to help when the FU-2 doesn't pull straight.

The "FU" line of park tools is rather crude, but mush more affordable than most of their offerings. The DIY version of the crs-1 is a pipe with a pvc reducing coupling on the end, coupled with brutish ramming motions. I've never had a problem with this "system". I do have to admit that, in removing crown races with a flathead and a hammer, i have done minor damage to a few races. However, i've learned to finesse it, and have gotten much better results.

A more fundamental question is upgrade from what to what?

You only need a press to replace the press fit cups in the headset. You can basically replace the whole headset by using only an allen wrench.

That's an interesting concept. How do you drive out the old cups and remove the old crown race and then reset the new crown race with only an Allen wrench? Do you get a real long one and use it as a drift punch?

Chris King's say they need a special tool set to keep from damaging the frame race edges,
the top one you will aways see if you do mess it up.

Threaded fork, I did a field strip of my CK headset for a frame repair, in Killarney Eire,
then pressed it all back in with its own threads.
