I've got a single speed that I love and have almost got it into the perfect bike for me. It has a 1 1/8" threadless headset and fork. I personally like the appearance of threaded (quill) headsets far better than that of the threadless.

In order to switch the threadless headset that I currently have to a threaded quill, I believe that I have to replace the fork and headset (and obviously get a quill), correct? I would like to find a fork that could work at my community bike shop, but they mostly have parts taken from older bicycles. Another question I have would be can I find 1 1/8" threaded forks back then? Or would my only option be to buy a new one such as 27" Steel Fork 1" Threaded Chrome Caliper Mount Cruiser Fixie City Road Bike | eBay ?

I'm still fairly new to the mechanics of bicycles so any help anyone can offer would be greatly appreciated,
Andy
