    I bought one couple weeks ago but decided to return it and going with a different fork. Not that it isn't any good but because I wanted a thru-axle fork.

    The travel on the All Mountain SL 130-150mm is adjustable through their Doppio air chamber with a shock pump. More air shortens the travel. the fork also have adjustments for positive and negative air pressures for preload/damping. There is a knob for 5 click TST setting(equivalent to rebound adjustment).

    The issue that confused me was the amount of travel the fork really had. With no air in the Doppio chamber, the fork should have 150mm of travel.. but unless the fork uses the ENTIRE length of the stansion when bottomed out.. it's going to have less then 150mm of travel because the stansion measured 150mm.

    This is the same for the new Marzocchi Z1 FR 3 150mm fork I bought where the stansion also measured 150mm. And that's the same when I compared the stansion to a Marzocchi 66 VF fork in the shop... So I'm wondering if for Marzocchi, do they call their forks 105mm, 120mm, 150mm, 170mm etc referring to the lengths of the fork stansion but not the actual travel?

    But anyways, the All Mountain SL is very light and would have worked for me but I decided to go with a stronger frame/build.

    Hope that helped.

    Phil.

    I just measured my Stanchion length on my 2006 AM1 and got 160mm. Are you sure you're not refering to Manitou Forks?

    Yeah, Marzocchi. The AM SL 130-150 is labeled as such.. but I'm wondering if it only has 130mm of travel.. same with my Z1 FR 3 sold as a 150mm fork but on Marzocchi's web site, it's only listed as 130mm... but that doesn't explain why the Marzocchi 66 VF's stansion is only 150mm also (there isn't a 130mm 66 VF as far as I know.)

    Going to bring my measuring tape and hit a couple of bike shops next few days!

    am sl

    The 130-150 version was released in the US as an OEM only fork. There are some out there now that are being some by some e-tailers. The 110-130 version was out as an aftermarket.

    The Supergo store (now Performance) here in San Diego has both versions of the AM SL. Both are sold as new in box forks and not OEM. If I remember right, the 110-130 version has external travel adjuster while the 130-150 is adjustable via Doppio air chamber using fork pump.

    The 110-130 am sl travel is adjusted through the negative chamber as well.

    No actually if you have less thane 80 psi in the negative chamber the stantion are 160mm long and you can have the full 150mm travel

    I'm pretty sure you can't get 160mm measurement in stansion for a 150mm marzocchi fork from my conversation with marzocchi yesterday.

    For the 66vf, you must have a 170mm fork and not 150mm.
