|   2000 Z 1 X Fly Negative Spring? | Gary
Feb 24, 2002 8:02 PM | | I can't find 2000 model Z 1 X fly on Marzocchi website, only back to 2001. Anyway, has there been discussion of improving/changing out negative spring in 2000 model? Is there even one of these springs? If so, does it help to change it, is it tricky to do, and where do you get different parts, etc. |

Coil springs will take a set and loose their "springieness" over time. There is an owners manual for the Z1 Xfly on the Zocch website. It's in the tech support section and is the first fork listed under 2000. It does require you to tear down the fork to replace the rebound springs. You can get the springs through your LBS/Local Marzocchi dealer. I am not aware of anyone that sells them online. You could call one of the online retailers that is actually a bike shop. Many times they carry products that they don't list on their websites. They are usually willing to sell them and ship them to you if you call and ask. Just a note, unless your rebound springs are worn out you really have nothing to gain by replacing them.

| Thanks, one other question.... | Gary
Feb 25, 2002 8:22 AM | | Found schematic on web site. I just didn't dig deep enough first time. One other question, there were complaints about this fork not getting full travel of 100mm. as advertised. If you know, was there a fix for this, I know they redesigned it for 2001. Was that the fix, get the the 2001? |
| 2001 fly fixed the missing '00 travel defect | derby
Feb 25, 2002 1:22 PM | | I found some softer short coil springs in an ACE hardware store spring collection with the same diameter as the topout springs in the '00 x-fly. I got some Marzocchi coil top out springs (softer than the air t-o springs) and stacked the soft hardware store springs with them on both sides. Had to grind the ends of the hardware store springs flat or they'd twist and scrape inside. Was a pain to develop but really improved the ride over little stuff. You can go as low as 4 cc oil in the lowers to gain a bit of travel, I never saw more than about 85 mm in my z1 x-fly
Put the same combo in a 2001 x-fly 100. The hardware store springs didn't need flat grinding in these forks due to design differences. Seen 104 mm travel, raised oil level to avoid bottom out.
Recently put HD coils in leaving the custom negative springs in. But they reduced crown height about 1/2 inch (no, or much less, preload with coil). Removed the extra hardware store spring and now getting full travel, with rare bottom out. Was a tad smoother over little stuff in the first 1.5 inches of travel, with the extra soft hardware store springs stacked. But there was more transition off the neg springs than stock setup. Best with the stock coil setup.
Hope that helps.

| 85mm is all I am | Gary
Feb 25, 2002 3:18 PM | | getting also. So I guess mine is basically normal. |
| Yes the redesign was the fix... | Squash
Feb 25, 2002 2:39 PM | | The problem with the 00 getting full travel was a design flaw that could not be fixed without complete replacement of the internals. Unfortunately the fix/redesign put in place with the 01 model can not be retro-fit to the 00 model. Most I've heard of anyone getting out of a 00 Xfly is between 85 and 90mm. Bottom line is, if you absolutely have to have 100mm of travel get the 01. That was the only real problem with the 00 model. Other than that it was/is a good fork.

| If you know..... | Gary
Feb 25, 2002 6:43 PM | | what was design flaw that kept it from getting 100mm of travel? |
| I'm not sure, but as near as I can figure out it had... | Squash
Feb 25, 2002 7:06 PM | | something to do with the compression rod length and the amount of seals and crap that they had stacked on it. Somebody goofed with the math and the rods came up long on seal and short on compression rod. Anyway, like I said I'm not sure what exactly the flaw was.

| the air chambers were too small | derby
Feb 25, 2002 10:17 PM | | The '01 design when back to the tried and proven open oil bath long used by Marzocchi. With a variable oil level in the new x-flys, the air chambers can be adjusted over a wide range.
At the time the Superfly and first x-flys came out they were the smoothest, most reliable, and stiffest handling air forks available. They are good forks. The newer ones a just better, and much easier to maintain.
