    fork AC length - rigid and suspension

    Thinking of replacing my '06 Reba fork with a rigid fork. Looking on the SRAM website, I see that the AC of the Reba is 490 mm. That's pre-sag I assume?

    What is a good AC length of rigid fork then to use as a replacement? there aren't any 490 rigid forks that I see any more (besides a few old Niner forks).

    Sussy fork A-C minus sag = rigid fork A-C.

    The trouble with common sense is it is no longer common

    Most suspension corrected forks will use an axel to crown that is equivalent to a 20% sagged 80 mm fork. All axel to crown measurements are static FYI.
