Axle to crown measurements

I intend on sticking a set of rigids in my 03 Tomac hardtail.Its an 80mm fork frame,Im thinking of a to c of 460mm?Are there any other variables to consider?

Re:

a/c vs travel depends on manufacturer:

Note the rigid fork length should be less than the suspension fork, because you generally run 20% of sag. I.e. To replace a 100mm travel fork of 470mm, I'd go for a 440mm rigid.

Usually look at 440-460 for an 80mm fork.

I got a 460 and have had no problems with a 60mm frame. An 80mm frame and a 100 mm frame......

Re:

Thanks lads,looks like 450mm or so should be fine so.

Since when were 460mm 80 mm fork corrected!?

Op should be looking at 420mm to no more than 440mm in a-c height.

I would in general agree with the last poster, but in truth there's no point in having this discussion without saying what length stem you're going to use and what kind of steering response you prefer.

Re:

As mentioned above the correct length rigid will be whatever the a-c of the current suspension fork with the sag taken off.

I replaced a set of fox 120mm forks (490 a-c) with a 470mm rigid, seems spot on.

At a guess 100mm forks would be about 470mm so use 450mm rigid

...and 80mm forks about 450mm so use 430mm rigid.

Roughly, of course.

Yes but bear in mind Fox forks are usually taller a-c anyway.

I got some 440 carbon forks that be ideal
