How to install 1 inch fork in 1 1/8 inch headtube

[Fishbike]

I am thinking about trying to build some sort of Frankenbike from the odd collection of parts in the parts bin, including a 1 inch carbon fork. The frame I am thinking about has a 1 1/8 head tube. I know Chris King makes a Devolution headset that should work, but it is pricey for a bike I am trying to build cheaply as a project. What are the alternatives to get the old fork to work?

Another company AC something, has an integrated 1 1/8 conversion headset (campagnolo spec) that is designed to be used with a 1inch fork. Comes in several colors and stuff...

Or, you know, lots of people on this forum are looking for 1" carbon forks. You could sell it and buy a 1.125" instead...

Do these affect performance at all, or are there any drawbacks?

Honestly? you dont notice. Back a few years ago when 1 1/8 was starting many manufacturers had bike built with a 1 1/8 front tube and were using 1 inch forks, then next year models came full with 1 1/8 forks.

Carrera did it I believe, some de rosas came like that too.
