1 inch threadless sus corrected forks - options?

[Dr Dremel]

I think when suspension corrected frames became the norm, the industry already moved on to 1 1/8". So finding a 1" suspension corrected fork (threadless or not), is going to be challenging. The only one I can think of is the Fat Chance BOI, and at this point you might as well have a custom fork made for you.

A suspension corrected frame by definition was made to run the longer fork
So I doubt that there were longer rigid forks avl as at the time as there was a general stamped to suspension . So a longer 1 inch threadless fork period correct probably doesn't exist.
There was no demand.
As bikeworkshop states 1-1/8 is the standard for longer rigid forks
Salsa Cromoto and Cromoto grande fit the bill perfectly but are of course the bigger stearer.

3rd gen pace rc30s, still with the removable steerer, axle to crown 420mm.

The shim to step the 1&1/8 crown down to a 1" steerer could still perhaps be made to fit, or the earlier 1"crown might take the legs.
Probably not cheap, but cool and a sound investment.

Apologies for the bad image quality but found this Ventana Marble Peak from mid 90s that has an 1 inc Judy TT sus fork with threadless steerer. So that’s where the question is coming from.

I have checked the bike in person and just can’t see how a threaded non sus corrected fork was fitted on it as its BB would have been way too low.

Unless I am misreading something these bikes came with suspension corrected geometry.

Perhaps a Ventana expert would be able to tell. I will ask on that thread too.

Head angle looks pretty shallow, maybe pedal strike was normal on this model.
You occasionally see early rockshox and others with inch steerers, but when the frames got redesigned to take more than 40mm travel from the fork, they were almost always up to 1&1/8.

Orange stuck with inch steerers till 94 or 95, but the sus geometry redesign hadn't take place.

The Judy looks too long in my eyes, I suspect that the Ventanas at the time came with a 5-6cm travel suspension fork Ventana only sold framesets, so there was no stock fork at all. Look at this one in an MBA test from Oct 1993:



Edit: @bikeworkshop was also right: "The Ventana had a relaxed 70 deg head angle". So a 39cm a-c rigid fork wouldn´t make it into a super nervous handling bike. In fact this would indicate it wasn´t sus corrected after all, as the typical "NORBA geometry" head angle was 71deg. That´s all presuming your bike is identical to the one in MBA.

Great! Thanks a lot everyone. I think I am now getting somewhere with it. Will have to find it another sus fork then. Something more conventional like an early Judy.

Not quite period but a sound fork
Marzochi mx comp was avl with 1 inch threadless. Air oil so proper suspension.
