If sufficient interest arose, it is possible to create an ‘oversized’ innicycle headset that would fit 1 1/8” threaded forks and would use 1 1/4” threadless stems. However, I see that as a very slim possibility for several reasons, mainly that there aren’t all that many high quality bikes using 1 1/8” threaded forks (relative to 1” threaded forks) and there are plenty of nice 1 1/8” threadless forks available to allow use of a 1 1/8” threadless stem where a threadless conversion is desired.

Sorry to disappoint. If you are itching to try an innicycle headset, it shouldn’t be too hard to find an older (pre-2000) road bike with a 1” threaded fork in your part of the world. I think you’d be my first NZ customer, too :-)
