Retro Ryder Headset
Retro Ryder Headset will allow one to use a 1 1/8th inch non-tapered fork in a bike that came with a once inch threaded fork.
Due to a increase in cost of materials, machining, and postage, head sets are now 56 bucks shipped to the lower 48 states. Sorry about that. If you're out of country or in Alaska or Hawaii, get in touch for shipping costs.
There are several different internal diameters of head tubes on one inch threaded head tubes.
The only one that will work for is one the is what is known as the "American standard" like the head tubes on made in USA Schwinn bicycles and many early BMX bikes and balloon tire cruisers throughout the decades.

The only way to know if our product will work is to remove your bearing races from your frame and take a measurement.
It must be 32.5 mm, give or take a point perhaps.
27mm will not work
30mm will not work
Nor will it fit on some pre-war bikes that had a larger diameter head tube.
You must remove your bearing races to be sure.

We will not know.
We cannot know.
There are too many bikes to make a data base of any kind.
You must remove your bearing races and measure the internal diameter of your head tube to find out.
