Help me find a frame for this Fastrax suspension fork

I found this fork last year. Purchased it, as I'd never seen one before, loved the color and the price was right. I am not 100% sure of the type of frame it will work on. Dimensions here-FASTRAX BICYCLE SUSPENSION FORK MODEL FS-10, Steerer tube length: 135mm, Steerer tube diameter: 28,6mm (1 1/8"), Thread length: 50mm. Anybody have an recommendations or something for sale that would work? I'd like to build something up with it. Prefer something in nice shape, size S or M. Thanks in advance.

You'll need asked something with a 100mm or less headtube.

This headset has a 35mm stack which is quite low, so subtract that from 135mm, leaves you with around 100mm to play with.

An orange clockwork, c-16 or p7 should be ok. Konas are probably out.

Hi, interesting fork, although just a Taiwanese copy of Mantiou and other forks from that time.
Typically this was used as OEM suspension fork for Bikes in a low or mid price band rather.

Nevertheless, just because you have asked, i found a nice picture from a bike show in 1995 where the german Brand Stevens was showing a prototpye bike with monocoque and full supsension. According to this article this bike has been co-developed from Stevens together with Fastrax.
Anyway, to my knowledge, it never made it into the Stevens portfolio or into stores.

Same frame showed up in 1997 as Koga Miyata SkyExpension, not with Fastrax, but with a Rond WP fork

Not sure if this is the information and bike you have been looking for, but to me using a Fastrax fork in a Fastrax frame sounds as most appealing combination.
