    im after some rigid forks to replace my 130mm recons on my sanderson been riding with them locked out for the last 7-8 rides and it tracks/rides so much better i can only find 26″ spec forks up to 120mm
    idealy carbon but any help is better than nothing

    Premier Icon firestarter

    Mine are 470mm if that helps


    and both are mine are (niner forks)

    470mm on the On-One carbon fork


    I’ve bought 2 pairs for Scandal 29er and experimenting with 69er Genesis Altitude:

    eXotic Carbon Rigid CC-F0365 29er fork – same as White Brothers – 465mm

    Salsa CroMoto 29 Inch Forks – 468mm

    Both are supposedly suspension corrected for 120 travel, after sag has been taken into account.

    Here, a list of a few susp. fork a-c – maybe it helps..

    oops…that’s a long post!


    forgot to say, I have a Rockshox Reba sl 29er fork which has 80mm travel, and a-c is 490, same as 120mm 26er forks.

    The exotic website has full a-c details for all their forks. I used a set of their 29er forks on my Soul to keep a 130mm-ish feel to the bike, very nice. It’s really obvious but do bear in mind that full a-c length on suspension forks is pretty meaningless, it’s the sagged number that’s relevant.


    thats true but is not the sag length calculated at 20-25% of full length:

    I also have an old frame with 100 susp. fork – and it was good to know actual length of that fork to know, after sag, roughly what rigid fork length I needed to keep geometry intact.


    i run bairly any sag due to the way i ride as need a stiff front end that would give under hard landings (hold the funny comments lol) but after riding locked out i realased i dont need the give and land smoother than i thought(prob as used to racing bmx)


    rp16v – from that list I found and posted earlier, the Recon AM 130 has a-c 509mm- to keep the geometry intact will you not need a similar length fork?


    correct but i as mine is a older fork and think it may be slightley shorter a-c and all 26″ forks are way short so testing the 29er water.

    might well plump for the 29er exotics as sugested.

    “thats true but is not the sag length calculated at 20-25% of full length:”

    Well, of the travel rather than the full length (and depends how much sag you use, as rp16v points out)


    yes, well clarified, I meant full length of travel.

    That’s what I meant though with no sag, he will need a similar length to his existing forks a-c…I think!

    As you said Northwind: It’s really obvious but do bear in mind that full a-c length on suspension forks is pretty meaningless, it’s the sagged number that’s relevant.

    In his case the sagged (or not) length is the same as full a-c.


    iv managed to get some 29er forks of a diamond back mojito to try so will bolt them on and take som epicks when i get a chance.
