If I switch out my cane creek head set for a chris king is there anything I need to watch out for? The instructions I have read make it appear to be pretty easy.It's on a reynolds ouzo pro fork.I know it can be to loose, but can it be to tight?Anything else???

My advice is to just pay a shop to do it. You need a few tools that not everyone has. Either that or you have to make a headset press, race removal tool, and cup removal tool. If you don't have all that, just let a shop do it.

You need to get the race off your old fork to put the new one on. You will need a race press for that. You need to take out your old cups and press in the new ones. While you have your old cups out, have the shop face your headtube. Unless you know for a fact it was done when the Cane Creek was put in, now is a good time to make sure it's prepped.

Good luck,

Russ

what does 'face' mean? also what is the name of the thingy that sits in the fork so it can be screwed in by the bolt on the top of the stem? it looks kinda heavy..why don they make those things out of carbon? forgive all the questions..i just trying to learn more wrenchin' stuffs :O)

Hey Kenyon, Facing a headset is where you use a two piece cutting tool to make sure the top and bottom planes of your frame's headtube are exactly parallel to each other. On most modern bikes this is not a big issue, but only because headsets are cheap to replace and usually pretty good. But the tool you use to face a headset cuts off material from the top and bottom of the head tube (often there is an uneven layer of paint here from the factory that needs to be taken care of) and makes sure the two surfaces are in line with each other. It makes sure the headset bearings are lined up properly so they work smoother and last longer. It's not a huge issue, but on a good frame that you want to last, you should have it done.

As part of properly prepping a new frame you should always do 3 things to it. Face the headtube. And chase and face the bottom bracket shell. Facing the bottom bracket shell is the same thing as facing a head tube. It's very important with things like the current Dura-Ace bottom bracket. The needle bearings require the spindle to line up accurately or they wear out faster. That may be a prime cause why people complain they wear out too fast compared to the Ultegras. The other thing you need to do is chase the bottom bracket shell. That is just when you take a thread cutting tool to clean up the threads inside the shell. Sometimes there is paint in there or the threads are warped by welding the frame... so chasing the threads cleans all that up and makes your bottom bracket go in easy and keeps you from damaging the shell with the bottom bracket itself.

Just proper technique to make sure your bike is properly assembled.

Hope that helps,
Russ

If so, it is not too hard to change a head set with tools you already have. You can remove cups and the crown race seat with a large bladed screwdriver and a hammer. You can install the crown race seat with a piece of pipe or by setting the jaws of a bench vice just a bit wider than the steerer tube and tapping under the (upside down) fork crown with a piece of wood and a hammer. You can install the cups by placing one of them on a solid wood surface and using the standard block of wood and hammer to tap on the opposite end of the head tube. In all cases, grease all surfaces to insure a smooth install. If what I am saying is quite clear to you, then you have the stuff to do it yourself. If not, then take it to a shop.
