|As i said this is my first road bike so i have many tiny problems preparing it.
So my new problem is this(i am a freshman OK). I want to install a new fork and headset to my 7005 alu frame but i cant remove the two cups (top & bottom) of the old headset from my frame (they are so tightly stuck, i cant move them!!). Can i leave them in and put my new 1-1/8'' threadless fork (my old one was 1-1/8'' threaded) or i must ?pull? them somehow out and replace them with my my new headset's cups?. Pls help!! Thanks...
(is there a way to do it without buying a special tool?)

|Park makes a "right" tool for the job. It isn't very expensive and I assume most bike shops will have one. I certainly wouldn't charge you very much for knocking out the cups.
Short of that, get your hammer and get out the crummy screwdriver. Drive out the cups by alternating blows on opposite sides of the cup.

|Pressing a headset back into position is another deal. I strongly suggest you go to the shop for this. It's quite important to press them straight, and this can only be acheived with an expensive tool all shops should have. And no, a hammer will not do. If you happen to insert a cup crooked, you could damage both the cup and the frame. Also, if the cups arent really parallel, the bearings will wear much faster than normal. Anyhow, you see where this all leads.
Just my 2 cents!

|You don't need a special tool to install the headset cups, but you do need some skills and a proper work area. The technique I have used for the past 35 years is to thoroughly grease the cups and frame, place blocks of wood on top and bottom of the respective cups, place one of the blocks of wood on a workbench, saw horse, cinder block, etc., and hammer on the other block of wood to drive the cups home. You have to keep everything square, and you want to go slowly, constantly checking that things are going straight, but I have installed dozens of head sets this way with no problems. This includes both aluminum and steel head sets in aluminum and steel frames. I've not had occasion to do an install in a Ti or CF frame, but I can't imagine it would be any more difficult. That said, it might not cost but a few bucks to have a shop do it, and if you are not sure of your skills, that may be the route to go.|

|You said it right there. You have 35 years of experience. I know you can bypass using the tool ( i've done it a few time, but i also have 10 years experience ). If someone asks how to do this, it's because he's never done it before, therefore i dont suggest using 'risky' methods. This is just the way i see it.
Oh, and how often do you change your headsets? Just curious!!

|With keeping my road and commuter bikes and my wife's road bike, plus sort of being the "ride group mechanic" I probably do one HS per year. However, my own headsets I hardly ever change. I've been using Stronglight units on everything (though I got talked into a King on my current bike) and these things don't wear out. I just changed my wife's after 13 years/70K miles because the top cup threads had gotten funky and it wouldn't keep adjustment.|

|It is amazing to me that more people have not found Stronglight. I have an old Delta that is going strong. I have spare bearings, but I doubt if I will ever need them. I tell people that it is a poor man's King.|| |
