Strength:

Smooth response, reliable

Weakness:

I changed to heavy springs a few years ago and over the course of one summer, the ETA quit working.

Excellent fork. Mine never leaks oil, works almost flawlessly (see ETA problem above), and feels great. I don't mind the eta problem because I climb better with suspension anyway. Fork occasionally bottoms out (I'm ~170lbs.), but I have to be doing something X-country stupid to reach its travel limit. Fork is a little flexy, but any fork that isn't probably doesn't belong on a xc bike.

I completely recommend this fork to anyone that rides trails, even with the occasional natural drop.

Strength:

It's 9 years old and it works great.

Weakness:

Can't really find any. It's 9 years old and it works great.

I needed a fork for a low-budget singlespeed, so I picked up a '97 Z1 Bomber with leaky seals for 40 clams on eBay. Changed the oil, put in some Enduro seals. Total expenditure 65 bucks. Also I had to scrape out the gummi-bear-like remains of the top-out elastomers and replace them with some random springs from another old Marzocchi. I think that maybe one of the damping cartridges is still clogged with the gummi stuff, but boy, this is a nice fork. It's not exactly light, but it's super responsive and has a nice soft landing towards the end of the travel. Not many adjustments, but I don't need to adjust anything, it works great with the stock springs. Conclusion: mountain bike fork technology was pretty much perfected by 1997. Buy an old Z1 and save your money for some nice disc brakes. By the way, this fork has two disc mounts, one on each side. It looks like you're supposed to run dual discs. Is this normal? Where the hell do you get a mirror-image caliper for the right leg? What about a hub that takes two rotors? How do you not kill yourself as soon as you hit the brakes? It's not like you've got 800 pounds of Honda Goldwing here to hold you down. What were they thinking?

chris   Cross Country Rider [Jan 24, 2006]
Strength:

durable, stiff, metallic ETA lever, dual coil

Weakness:

5.7#(?), does not use all 130mm of travel, even ever a 3~4' jump. initally had 105mm of travel, sent the Z1 to factory for warrenty work ($70 for shipping, four weeks), came back at 135mm travel.

I use the ETA lever on road climbs toward end of an exhausting ride, where the reduced travel and increased stiffness helps (psychologically, more or less) to sprint over the hills. on dirt, i leave the ETA open for a full range. It's like having two forks in one... in performance wise and in weight wise...

I wanted a plush fork for all around xc trail riding that i can rely on...and my Z1 ETA QR delivers.

And when the going gets rough, the tough fork gets going, big time.

I like to climb, but I love the descends, fast and rough: 5" Z1, 8" M4 disk, and 2.5" WTB tires are fun and assuring combination.

The 2006 Z1 versions may be a tab lighter, if that matters to you.

130mm~150mm Z1 forks are among the best xc forks. As long as you're not a serious xc racer that may wish to have a Sid or a Fox 100, Z1s are the "bomb."

Andy   Racer [Apr 13, 2007]
Strength:

Perfectly smooth, very sensitive, perfect for Dual slalom, full use of travel. Very good all round fork, but not for going up hills - suck the energy out of you! freeriding, 4X, although todays forks come with more travel. Oil + dust seals last forever! Dust seals work to perfection! An exremely well made fork! Up there with todays Marzocchis.

Weakness:

There is a compatibility issue for disc brakes, I just tried putting some new shimano XT Discs on mine. The IS standard mount changed after these forks were released, therefore todays IS mount adapters do not fit on the forks. Unless you have some Hope disc breaks or an IS mount from 1997/1998 then you will have to use V- brakes.

At the end of the day, these forks made history! I see young lads up at the course riding new 2006 Z1s, dirt jumper forks etc...Z1 97's do everything you need them to do, except XC! I have had these forks for 10 years now, and they still work better, smoother and more sensitive than todays ones. I feel that with marzocchi forks today you cant really be sure with what you are getting, but 9/10 years ago, everybody new that the Z1s were the best, and that you new they would be almost indestructable, even the pros admit that very few forks over the last decade can compare to the 97 Z1s! If marzocchi re-released these forks, with the updated disc mount, then the Z1s would set the standard again, like they did so brilliantly 10 years ago. So dont waste £500 on a set of brand new bombers, get hold of some 1997 Z1s for £100 and you will be laughing your head off all the way down the course!

Keith Elliott   [Oct 26, 2001]
Strength:

Stiff, real springs, real damping controls, ECC

Weakness:

Price (only had to buy it once) and weight (I couldn't care less)

Update to my past eview, where I had the fork installed on a Giant NRS. When I finally got my Orange frame I added the 5" springs to the fork, and put in an ECC cartridge as well. The ECC locks out the rebound, so the fork stays at the bottom of it's travel when you flip the switch. This is easily worth at least one gear while climbing, and gives tons of steering precision on really steep climbs. The whole bike goes down hills like no "cross country" bike has a right to, covers miles efortlessly, and still weighs 29 lbs. with a Pazzazz downhill bar and stem. That's with 5" travel on both ends and hydraulic discs, mind you.

As for the ECC-other brands are doing variable travel forks, and my buddy that owns a shop has gotten about half returned that he's sold, with stripped or broken bits inside the adjustment mechanism. He say he's NEVER had a Marzocchi warranty claim. And unlike compression lockouts, big hits are acting against the springs themselves, not the valving in the compression damping circuit. There's a special bottom-out spring in the Bomber, so it don't blow up if you forget to flip the lever back.

stephen cameron   Cross Country Rider [Oct 03, 2001]
Strength:

plush 5 inches of travel - absolutely silky smooth and irons out everything in your way. nice and stiff - tracks really well. also have had zero maintenance and trouble from this fork

Weakness:

my z1 mcr is the 2001 model with the lockout on the travel - great for hillclimbs and road sprints etc BUT i find when locked out, the rim is bent towards the opposite side to the lockout (which is only on the left side of the fork) making it impossible to run the brakes (xt v's) nice and close to the rim (ie it rubs when locked out. i've even had some huge washers made up for the hub (equivalent to 20mm axle) to try and make it stiffer but still to no avail. i'd really be interested to hear from anyone who has had or overcome this problem.

awesome freeride fork. perhaps a little heavy for cross country racing. watch out for movement of the rim when using the lockout.

Mike Schelske   Weekend Warrior [Nov 23, 2001]
Strength:

Stiff,Plush,Tracks Well,ECC Rocks,nice range of adjustments

Weakness:

The Cryofit crown started makeing noise, but that can be fixed by poaring lock tight in between the stanchions and the crown

This fork kicks ass for what it was made for. It can handel some of the roughest trails and come back asking for more. If your looking for quality 5" trave fork that will take beatting. This is a good choice.

I just wouldn't sugest this fork to someone that is worried about saving weight on their bike or someone that races. But other then that Its a great all around fork

Balboa   Downhiller [Jul 14, 2001]
Strength:

super stiff, super plush, ECC is dope for technical climbs, 5.1 inches, SO MUCH FUN

Weakness:

huh?

this fork is dope, prefectly balances my 4.6 inches of rear travel, so if you're looking for a relatively light, long travel fork, this is it. You may think climbing with 130mm of travel is difficult, but when you're able to lock out the rebound and decrease the travel to 2 inches, there's no problem at all. The absolute BEST single crown fork out there...no complaints here.

Kern Osterstock   [Sep 23, 1998]

I bought the 1999 version with 5 travel. The owners manual says the stock shock is rated for riders up to 180 pounds. That's BS! I weigh 190, so I figured it would work. Not even close. I put it on the bike and went to pogo city. Not only did it pogo, but the springs rattled like beer cans in the tubes. With the flimsy springs it was tough to bottom it, but just sitting on the bike used well over an inch of travel. Yeah, I did the preload and damping adjustments. The first fix was my l.b.s. adding more oil which made no real change. So I ordered and installed the heavy springs. What a change! The fork now works like it should have all along. My feeling is that the stock springs are good for up to a 125 pound rider max. They should come with real springs in the box, not 2 weeks and $40.00 away. Do I like it? Yes, I think it is the best single crown unit out there. Another gripe: Mine was apparently early production and the machine work on the fork bridge looked like it was done with a knife and fork. Razor edges and no deburring are out of place on a $600.00 fork. Also, the instructions that come with the springs don't even come close to the installation process. Fortunately, the manual will walk you right through the job. My rating is five chilis for the final product, less one for the cheesy springs and sharp edges.
