I need to start this by saying that I am a noob to road bikes but trying to learn quick!

Okay I just purchased a used bike and I want to change the headset on it. The bike is a Cannondale R400and it has an adjustable stem on it that I can't stand. I am on a business trip so I am not in front of the bike. What I am trying to figure out is if anyone knows by looking at this stem if it is threaded or not. I am trying to figure out what kind of stem I need to replace it with.

Here is the pic

it is threaded, on threadless headsets there will not be that big nut right under the stem

I just realized that I said headset in the subject and I meant stem. I guess I am more then just a noob in the bike world too.

So my only option is to use a threaded stem to replace it or replace the fork right?

nashbar has both threadless stems and things that convert threaded forks to accepted threadless stems

You pointed out it was threaded on a threadless stem. If I want to change everything out without going the nachbar route I would need to purchase a new head set, fork and stem correct?

What are the advantages and disadvantages of going the nasbar route. I am not going to racing so should I not worry about it?

If you want to keep your existing fork then your best best is a quill stem. You can get an extender and then go threadless but if it were me and I wanted to go threadless I would just get a new (uncut) fork.

I don't have the bike in front of me so I am not sure of this but since this is a Cannondale R400 would it take a 1" stem or a 1 1/8 stem if I was going to go the quill route.

or you could take it to your LBS and be like, " what do I ned to meke it into what I want?" that would take care of it in a jiffy.

I think you have a good point there!

Threadless stem adapter is the way to go. Have them on 2 bikes. Allows change of stem if you find you need to change or upgrade.
