There's a risk you will damage the alu nut if you hit on it with a socket. A damaged nut might make the shaft rotate with the nut. I remove the nut and use something with a hole that fits over the rebound screw.
That was fantastic, Christina. You explained this better than any other presenter on any cycling channel. I am so glad that Pinkbike had the wisdom to hire you. I think Pinkbike should have a weekly show called something like "Christina's Tech Tutorials". You make learning fun and easy. You are articulate, intelligent, thorough, talented, and entertaining. The perfect teacher. I hope to see many more videos like this, in the future.
I'm not due for a service or anything, but this music is chill and your presentation is relaxing. I listened while doing dishes and it's just what I needed to wind down at the end of the day.
Would love a video on a full frame disassembly of a full suspension bike. That's a job I've been putting off. Replacing bearings in pivot arms on a Demo8 is pretty intimidating.
Well done. I've watched countless fork service videos. This one was straight to the point and useful. As a recovering bike mechanic, I even learned a new trick (beaker for suspension fluid). One request: I'd REALLY like to see the same level of no-frills description for LSC tuning. I'd like to see someone explain and demo the interplay between fork air pressure, air volume, and LSC for different riding conditions. I'm one of those "run almost zero LSC and hope for the best" luddites, and I'm sure I'm doing it wrong. Not sure if that is appropriate for a winter overhaul series, but definitely something I'd love to see.
Just serviced my Z1 following these tips and it was really helpful! My seals were a pain in the ass and I beat the hell out of them trying to get them out... But after a year of hard riding and bikepacking it was leaking oil during rides on one side anyways so they needed to be replaced. Thanks Christina and PB for an awesome video! Definitely need more like this!
Great video, and I'm super glad I found it, as I will be helping a friend service his Z1 soon. I can't find a service manual anywhere for the Z1 Marzocchi, and fox websites only have a Z2 full rebuild manual listed on their service pages.
Great video... personally I use only 5 WT on the damper side and for the foam ring on this side... 20WT for foam ring only on the air side... to avoid mixing the oils.
I would like to see how the compression and decompression ( rebound ) controls affect the valving inside the fork. Logically theses valves allow flow in one direction each. Are theses controls actually a very long knob stem that reaches up inside the fork ? I feel a better understanding what these knobs/levers are actually doing and being able to mentally visualise the inner workings can only lead to a better suspension set up. A simple Marzocchi Z1 Bomber Air , having basic low speed compression and rebound ( which just co-incidently I have ) , should keep it simple and straight forward. Good tutorial.
If u got rockshox u don't need half of this for a seal change Allen keys, mallet and the correct fork oil and syringe plus the seals and foam o rings. Seal setting tool is nice to have, but not strictly necessary. A couple more stuff is necessary for a damper bleed or replacement, or airspring replacement
Things like this are best learned on something shagged. Look around on those buy/swap groups or your local newspaper. Pick up a set of clapped out forks to learn on. Sure it's hard to cock up but it's still better to practice on some knackered old things than to risk a £1000 set of forks. Besides, if you get those old forks working nicely someone might want them for a bit of cash.
My old reliable Marzocchi Junior-T only needs every 10 years an oil change and the sealings should be cleaned regularly. After cleaning i apply a µ of silicon-spray, compress the fork 2 or 3 times and remove the surplus silicon. This let the coating of the standpipes remain like new with literally zero breakaway torque. 6:28 I use household wet wipes (melon scent). No lint and the right ammount of cleaning agent. They're also pretty useful to get rid of this nasty chain goo. Don't use them on brake disks/pads because of the soapy ingredients.
Great tutorial. I have a set of Marzocchi super leggera Corsa 29 with remote lockout. Can they be serviced the same way or are there a few other steps I need to do to allow for the lockout mechanism??
Does these forks not having the pressure bleeding valves a drawback for someone who doesn’t want to open the fork up when you don’t have to service it?
The valves are for letting out excess pressure at altitude etc. All other forks work perfectly fine without them, they’ve got to keep coming up with gimmicks.
I did lower leg service on my Fox 34, and I was always wondering WHY those lover legs air shaft needs to be punched out? Why you can not just unscrew lower legs and take them out from upper legs? Can anyone explain to me? Thanks in advance
As a guy that's been swinging a hammer for as long as you've been on the planet I gotta give you props on the way you swung yours you know what you're doing. Thanks for the great info 👍🏻
I'm 40 and for somewhere from 2/3s to 3/4s of that I've been a DIY bike and car mechanic - and never dreamed a women would teach me in this field. However, I don't mind her doing it, don't know if it's something to do with me or her. Greetings from Latvia and thanks for the clear and simple introduction into this "dark art".
For grip and grip 2, you should be soaking the damper side foam in 5wt-ptfe, not 20 gold. You're gonna end up working that into the damping circuit, and damping with 20wt is no fun.
@@pinkbike Yep there is not enough oil in the foam rings to contaminate the damper bath oil, you can watch Jordi from fox do it on Rachel Atherton Fox 40 on an episode of Dialed.
No need to use the hose for putting oil in. It's easier to suck oil in syringe, easier to put oil in fork and most importantly, not much oil is wasted.
A few inches of a proper diameter PVC pipe will do the job nearly as well for pennies. The seal driver is probably faster and easier to use but it's a marginal difference when you're only servicing your own bikes.
Nice one, thanks Christina for explaining it so well. I have seen that guy doing quite nice edits and runs on riding trails, check him out is really worth it th-cam.com/video/rWAD6cx5loE/w-d-xo.html
First seconds of work and already a fail. First notice the pressure before releasing the air. Going on with this extra expensive tools while other guys which know how it works use tools everbody has at home. Also wearing gloves and then using a brush to get some grease to the dust wipers is bad because if u loose a hair it will be on the wipers.
@@hjohn2 I’d rather have whatever it leaves behind over water in the fork, if the lower is completely disassembled there shouldn’t be any rubber or plastic in there, I also don’t rub it on my skin because I’m not a pinecone… not to mention it is a much better degreaser than iso
You can loosen the foot nuts and use a 10mm & 15mm socket with a hammer to unseat the air spring & damper.
Came here to comment that!

@@kentsolgule5362 screw the nuts on as far as you can to spread the load amongst as many threads as possible. And use a soft hammer or wood.

No she didn't. Check out Doddys video on the Fox 36 and the Lost Guy.

Tap them in a bit first to break the bond between the seal and the fork.
One of the most straight forward fork service videos I’ve seen. Thanks!
Thanks for sharing this video - just did a service on my Z1s and the vid made it super easy!
Sweet thanks, a shame I don't own that purpose-built 540$ Park Tools oil catching bucket, otherwise my fork'd be so serviced right now.
😅😅
Awesome video!!! I´d love to see a full service of a Marzocchi ZI coil, since I haven´t found much info on how to do it, keep up the great work!
Great video, and I'm super glad I found it, as I will be helping a friend service his Z1 soon. I can't find a service manual anywhere for the Z1 Marzocchi, and fox websites only have a Z2 full rebuild manual listed on their service pages.
Great video... Thanks. How to adjust derailleur properly. How to clean service sticky pistons on your brakes
I like the service videos. Keep em coming!
Thanks James! I'll have a think on the next one -Christina
Tap the seals IN a little before removing, to break the bond between the seal and fork. They'll come out much easier. Motorcycle mechanic tip.
Great video... personally I use only 5 WT on the damper side and for the foam ring on this side... 20WT for foam ring only on the air side... to avoid mixing the oils.
me too! ;)
More service videos please, that was very good
Yay! Christina is my favorite! Thank you.
glad to see you again.. 🥰🥰🥰
very educational, you have my vote for more vids like this one. Maybe a rear shock service next? Again, great presentation and information.
Yeah very useful video 🤟 I have a Bomber Z2, the process it's almost the same, right?
Marzocchi best brand EVER!! 🤩💪
More of this! Would love to see how to straighten a hanger, cut bars, etc
Thank you! Just bought stuff to service all our forks.
i want to see more videos staring Christina, she is great

A simple Marzocchi Z1 Bomber Air , having basic low speed compression and rebound ( which just co-incidently I have ) , should keep it simple and straight forward.
Good tutorial.
I've got this service coming up on my Z2 pretty soon, definitely want to do it myself!
Then better whatch videos of guys which know how to do it and you will save money for useless tools you didn't need.
Getting that little retaining ring back in was the final boss!
What retaining ring?
I usually save the springs from the seals just in case they get munched during other fork services when you don't change out the seals.
Agreed, I always keep the extra bits that I don't use in the spare bin -Christina
i followed this exactly is my rockshox a bomber now?
Looks easy. Especially when you have a loaded shop and all the tools
Facts holy, it’s so annoying when you don’t have what you need
You don't need all the Tools. Just get what you need to Service your Fork Model.
But it is actually easy, and you only need just a few tools, certainly not a shop.
You don’t need all those fancy park tools. You can do this service with basic hand tools you probably already have
If u got rockshox u don't need half of this for a seal change Allen keys, mallet and the correct fork oil and syringe plus the seals and foam o rings. Seal setting tool is nice to have, but not strictly necessary.
A couple more stuff is necessary for a damper bleed or replacement, or airspring replacement
Great tutorial! You really don't need the specialty tools if you're careful though, so don't get intimidated by those.
Just wanted to confirm, would those service video be the same for the Z2 Bomber fork?
Z2 is 34mm instead of 36mm like the Z1 so will need different seals and maybe oil depending on the damper but the process is exactly the same.
Thanks having a Z1 this is the 1st service video I’ve found! You rock! Now just need to find out where to buy the new seals/oils and tools
Thank you! Appreciate that! Any local shop "should" order those in for ya -Christina
Awesome.
Just coming off a video where Christina was ripping with Remy.
Christina you’re the Best 👍🏾

Can you do a video on the a z2 service? The only video on TH-cam is in Russian and fox websit only has full rebuild instructions.
Just sent mine in to fox for a service.....good thing my buddy works there and will do it for beer 🍺
How do you remove the cap for the air pressure side of the fork? That way I can set it up with the right psi for my weight.
Great instruction Christina!
Hi,nice vid. Can I use FOX36 seals on my Z1 coil? I read chassis are pretty same like on FOX. Thanks for answer, cheers! :)
Would it be possible to provide the maintenance service for the Marzocchi Dj1 2017?
What is a little excess oil after a few rides? Is anything between 1cc-3cc normal?
Great tutorial. I have a set of Marzocchi super leggera Corsa 29 with remote lockout. Can they be serviced the same way or are there a few other steps I need to do to allow for the lockout mechanism??
Can anyone please help where to find instructions or service manual to overhaul the Super leggera forks listed above??
Is this the same procedure for bomber DJ?
Does a rear suspension requires an oil change as well ?
what syringe should i use and should a different syringe be used for the air and damper sides?
Pharmacy syringe or if you know a nurse get a free one.
@@redtobertshateshandles thank you!
Is there any real benefit in upgrading to something like SKF seals, is it worth the extra money?
They're 97.38% easier to press back in than the Fox ones.
Don't know about the SKF's, but the seals from Push have noticeably less stiction.
I reckon there are about a hundred videos on TH-cam about this. Was another one needed?
Sería bueno con subtítulos en español. gracias
What happens if there is rough edges/scrtches inside?
Does these forks not having the pressure bleeding valves a drawback for someone who doesn’t want to open the fork up when you don’t have to service it?

I have something rattleing in my bomber dj forks. Help.
Where can I buy the service kit in the UK?
I did lower leg service on my Fox 34, and I was always wondering WHY those lover legs air shaft needs to be punched out?
Why you can not just unscrew lower legs and take them out from upper legs?
Can anyone explain to me?
Thanks in advance
The shafts wedging into the lowers is what keeps everything sealed, so oil won't leak out.
Not cold, no snow and not wet here in Florida. So we are not servicing our forks, we are riding today!
Forks still need servicing when used in dryer conditions
@@danp2509 Nope, just ride and enjoy. Forks can last 20 years without service. j/k with this and my previous comment.
No snow and not wet, but it definitely got colder here...at least until Florida decides it's done with winter next week XD
@@djsercy5879 Yes, it is cold for Florida but great for riding.
hahah May or may not be a little jealous -Christina
As a guy that's been swinging a hammer for as long as you've been on the planet I gotta give you props on the way you swung yours you know what you're doing. Thanks for the great info 👍🏻
I appreciate that a lot, thanks! -Christina
And if you own a mtb with a coil fork sr suntour xcm it's cheaper to replace it rather than service
Really good!
It's pretty much winter ?
If you want a more detailed overview, check out The Lost Co’s guide in their channel.
Thank you love you but i dont have marzocchi fork
Not servicing the air spring during a lower leg service is like not changing the oil filter when changing the oil on your vehicle.

No oil in air chamber?!?!?
Those safety glasses make pretty good night riding goggles for people with large faces. Looks dorky but works.
More tech vids please 😎
No need to use the hose for putting oil in. It's easier to suck oil in syringe, easier to put oil in fork and most importantly, not much oil is wasted.
What are you talking about?
Air can service on your shock would be cool.
Have done this before, with guidance... I'll need some more practice -Christina
Can you use 0W20 full synthetic motor oil instead?
Christ not that much has changed from my old orange Z1 bams what 20 odd years late
Expensive oil (and two types) for a mid-tier fork.
She so good! I can watch her all day! Big crush!
Chappetta 😘
Wow thos arms can bent those forks easily
Try putting the seals in without that special tool 🙄
Not willing to wreck the seals trying haha -Christina
A few inches of a proper diameter PVC pipe will do the job nearly as well for pennies. The seal driver is probably faster and easier to use but it's a marginal difference when you're only servicing your own bikes.
@@frankthetankricard I guess you have to be careful to not drive the seal too far down? The tool has both a stop and also makes sure it's straight.
so i'm not the only one using my italian mozzarella plastic container

I like servicing forks because I get to use a hammer
I don’t think my dad will trust me doing this to my bike
Rad , wanna see more of your kick ass self Christina , maybe how to put a dropper post on a bike without one, or how to seat a tubeless tyres
LOVE both those ideas. How to service my dropper would be a good one! -Christina
i want you to change my sporm
‘’Gently’’ meaning use your whole body weight😂
shes fit 😍😍
My God she's gorgeous

Do not use isopropyl. Use denatured instead.
@Skulls Road Use whichever you got, this is not a cooking video.
@@frankthetankricard oh my mistake. I forgot how good water is for the fork internals…
@Skulls Road you’re not making a cocktail ya muppet😂
Denatured alcohol leaves a residue, can attack some rubbers and plastics, and is harsher on your skin. Isopropyl does none of the above..
@@hjohn2 I’d rather have whatever it leaves behind over water in the fork, if the lower is completely disassembled there shouldn’t be any rubber or plastic in there, I also don’t rub it on my skin because I’m not a pinecone… not to mention it is a much better degreaser than iso
that foam is piece of junk. just trash it. as soon as the oil "leaves" it, its becomes sticky... and have zero benefits
I heard do not lube the Plastik Seals or they will just pop out the Lowers on an high Compression.
Yeah. I'd just make sure it's clean and smooth in there.
