    Sticky Bomber XC600

    Have a Giant Reign 2 with a Marzocchi Bomber 600TST2 fork that isn't the least bit smooth. It builds a load then releases like the fork is sticking. It's done this since I got it new and the LBS says this isn't a problem, does this with the rebound at all settings so that shouldn't be the problem. When I let all the air out and pump it up it takes in air but doesn't rise as I pump, it jumps as it builds pressure. My rear shock rises smoothly as I pump air in and I feel the fork should do the same.

    One problem it's causing is every time I get off the bike when setting the sag it's a different measurement, rear is spot on each time.

    it appears as if the people on mtbr have had the same problem

    There is about 10mm of sag that won't let the fork extend all the way even with 50 psi. I believe the fork oil is too thin.

    When adjusting the air pressure some oil leaks out of the valve.

    The so called lock out lever does not have sufficient notches to hold the lever in intermediate positions. But I always ride it unlocked anyway so it doesn't bother me too much.
    Hydrolocks at 129mm, blows through travel too easily, too much oil from factory,
    I am 250 lbs when geared: I have to run 65 lbs in the air chamber to keep proper sag. but the second i stand the shock almost bottoms out. to fix this i would have to run over 73 lbs and i think that would blow the chamber.
    another solution I found was to run the tst one click in.
    Would prefer a bit more adjustability

    You might consider finding a new shop if they say that kind of performance is normal/acceptable. Maybe call Marzocchi direct if your shop can't.

    I took the bike in today, he immediately said it's not right and is covered under a 3 year warranty. I think the first time I took it in (last spring) it felt OK because I was running 90 psi at the time (see below) and it smoothed things out to where he couldn't feel it. Today it was set to 50 psi and with more travel & less resistance he had no problem feeling the sticking. He also said he's sent a number of forks back for the same reason.

    As for the shop they are great people and treat me extremely well. He's going to try and get them to ship new internals to get the bike back to me quicker. I think the first time was my mistake in setting it up wrong.

    I agree with the statements above, even set to be proper sag I blow through travel way too fast, that's why I was running such a high psi last spring. The sticking issue has become more noticeable as I try and dial in the proper setup. I think this fork is going to take more pressure and less sag to run properly.

    And yes, the lockout will only stay put in wide open and totally closed.
