Z1 FR SL Question
This is the fork on my new bike. The ecc-lock down does not want to stay down for very long on the climbs. At first I will stuff the fork down and it works fine but after 10 minutes or so I notice that it is almost back to fully extended.

Does anybody else have this problem? Any set-up advice?

    The Z1 FR SL uses the ECC5 which is a 5 position extension control cartidge. The 02 uses ECC, the 03 uses ETA. The 5 position ECC5 adjusts rebound damping from wide open to fully locked. Sounds like an oil volume issue to me, though I'd definitely not rule out a defective, or loose piece in the ECC itself.

    When you turn the ECC knob, does the knob work itself back to open, or does it stay in locked out position, but without effectively locking the fork?

      Sorry, reading over this post, I realize I kind of pieced together some stream-of-consciousness thoughts that may end up not making much sense:

      The Z1 FR SL is an 04 fork. Comments and suggestions are made based on the specs for the 04 Z1 FR SL. The 03 Z1 series used ETA, while the 02 series used ECC. The ECC5 is a modification of the 02 ECC in that you can Set the ECC to 5 different positions. Wide open the ECC does nothing to the rebound settings you already have dialed, then each click increases damping until you reach the 5th position which locks it out completely.

      If there is not enough oil in the fork, the ECC5 may not function properly. Marzocchi builds a great fork, but they don't always spec it from the factory with the correct amount of oil. I'd check that first. After checking and adjusting oil height, I'd look to see if the ECC5 knob stays put when you turn it, or if it unwinds itself. If it stays put, but you get lockout failure even with the right oil height, then you have a defective ECC5. If it unwinds itself, then it's still a problem with the ECC5, but a different one entirely. Either way, if the problem isn't oil height, send it or take it to Marzocchi. Their customer service is second to none.

        thanks dude. I think the knob stays in place. One more thing. It only seems to work when i dial the knob all the way over to the right or 5th position. In any other position the knob does nothing. Reviewers on MTBR seem to have this problem too.


        I will have the shop check out the oil and what-not (I dont want to mess with my fork). My bike is there anyway because of a problem with the 5th element :<.

          Sounds like an oil height issue. The knob has 5 positions, each increasing damping until the fork is locked out. If there is not enough oil, the mechanism doesn't function correctly. Get on the Marzocchi web site and look up the oil height for your fork, or just take it to a trusted LBS and have them look it over. I'm sure a few ml of oil will solve your problem.

              Thanks man. I'm riding road tomorrow, and I'll be on the XC bike within 2 weeks for sure. I don't do casts or painkillers unlike some people here.... :-)

    I read a post just like this on mtbr.com and most people says that it is normal for the fork to extend after 10-15 minutes. Go do a search in the shock forum there....it was only a week or so ago.

      you know what....you might have been reading my own post from a week or so. I just do not want to believe that the fork is designed to creep back up to fully extended, that would suck....
