I’m gonna have some trouble communicating how incredibly helpful and in-depth to the extreme that this video was, I now feel like I literally know forks inside and out and feel that I would be confident enough to have a go of the lower leg and air spring service (which I didn’t really know what it was before). So thank you for putting in the huge amount of time to explain this reasonably understandable process in such incredible super extreme detail, and i now know what an air spring is and what it does and how to service it. I love these mechanic Monday videos and look forward to the amazing future episodes!
I completely agree with Rowan ! I’ve never seen such a valuable videos, guides od manuals as those from you ! Have been watching more from you this morning and this one made me subscribing a even expressing my appreciation of you and your way of doing videos. Have been showing this video Today to 2 more friends of mine and we all feel now confident doing this level of servis ourselves. Thank you ! You represent the role model of how guide videos should be done. When you advise to clean inside of guffers/main bushing, you also explain why. When you mention negative chamber, you expain what it is and what it does. Amazing and best ever !
Thanks a ton! I wanted to make a full-on video guide rather than just a 5 minutes video without showing how to actually do the things like every other video out there haha.
@@TheLostCoPlease make a tutorial whit the suntour cadtidge pcs (durolux, auron and aion). In Internet don't have good information and tutorial about this.
@@santiagofuenzalida5168 suntour suspension are good but that's the problem: they are not popular, suntour has made itself known not for their good products, but for their really low end xct/xcm and xcr forks. since they are not populare there aren't any tutorial. suntour website has some video for forks service, check that
If your gonna make a tutorial...go big! All your videos are so comprehensive. Thanks for doing that. It must take so much time to make these videos and your audience takes notice. 👍
Haha thats my attitude for sure! Thanks for thinking about how long this takes, as this video took about 2.5 entire days to finish. But it feels great when the video is done and uploaded 👍👍👍
💥 READ THIS BEFORE YOU START 💥 1) You will also need to inject 3cc of Fox 20wt Gold Oil into the positive chamber of the air spring. I forgot to film and edit that part into this video. We will now mix Slickoleum and 20wt Gold oil together to create about 3cc's of the mixture, and then slather that on top of the air spring piston and lightly around the seals. 2) The reason this fork sucked down into it's travel was not due to the amount of grease on top of the air spring piston, it was simply because I let the air out too quickly. Just let the air out more slowly and hold the fork up in it's travel and that will not happen. I have been fortunate enough to work with some of the best suspension mechanics out there, and I've learned a ton over the years. Never stop learning! -Mike
Best fork service/rebuild tutorial I've found online. Newbies like me need this level of detail to avoid screwing something up! Initially I wouldn't have even thought of doing the air spring service with the lowers but now I'm confidently going for it. Thanks for putting in the effort ++++
Hi. Thank you for this great video. I have just one question. Aren't you forgetting putting in the 3cc 20w gold oil on the air side in the air champer? Or is it intentionally?
@@TheLostCo thnx for this really helpful video! would it be possible to edit the air chamber 3cc oil with some kind of text or something? i think it would help people like me. cheers and thnx again!
That is my fork in the video! Thanks Mike, I appreciate the attention to detail and how clean all the prep work was. Now I can service my own fork, but will surely grab the parts from you!
Anytime man! Thanks again for sending that fork in, you'll be stoked on how the fork feels with the new damper and no air stuck in the negative air chamber!
Man you're a blessing to have in the mountain bike world. All of your videos are so helpful and well made. Cheers for making my DIY bike maintenance and suspension set up a breeze!
Omg, legend. Actually full detail and sharing all the nuances and things to look for. Awesome. I wish there was more content like this on TH-cam... Thank you!!!
Yes, i'm going to service my fox 34 float performance and there is this 3 cc of oil in the air chamber. So actually i've to open the valve cap and put 3cc in there right? I don't see anyone doing it!
Great Lesson 👍 quick question for anyone. The fox website calls for 3cc of oil in the air chamber , Is this required??? if so do we just release the air and open up the top to add that extra oil ???
Just doing the service right now. Don't you have to use the fox gold on the foam ring on the air side and the other oil on the foam ring on the damper side?
Question: The Fox document with all the oil types and capacities, lists 3 cc of 20wt oil in the air chamber. But you didn't do that in this video. Should that be done? If so, where/how exactly do you add that oil?
Yes, unfortunately this part got lost in editing. The service guys at the shop will take a fingertip full of Slickoleum and a fingertip full of Fox 20wt Gold oil and swirl it together in the air chamber on top of the air shaft piston.
Yep! Slick Honey, Slickoleum and SRAM Butter are all exactly the same. We have a blog article about that, too: thelostco.com/blogs/blog/mtb-suspension-grease -Mike
Thank you very much for the video, it was exceptionally well done. I had two questions for you. First, when servicing the air spring do the o-rings/seals need to be replaced? Second, in the oil volume chart for 2018 Fox 36 (I have one with Fit4) it mentions 3cc for the NA2 Air Chamber. I didn't see anything about that in the video. Thanks again.
The video doesn't show that step. Release all the air pressure, then unscrew the top cap on the air side, add the 3cc of 20wt oil, then replace top cap and repressurize.
Hi! I have a step cast 32mm fork. Today I put a click more to the rebound knob and a rubber oring fall in pieces down. Is it necessary to replace it before ride again or can I wait until the next check? Thanks a lot
It's hard to say without seeing it in person but it sounds like it should be taken apart and inspected before riding it again. If you email us a picture at sales@thelostco.com then we can help figure out what's going on!
From a career mechanic (motorcycle)......Great job of going in depth for all your processes and shop tricks. Helpful hint.....when you are dealing with a small part that is likely to become a "f**k spring" (small non-magnetic part that will likely find the largest and most immobile thing in your shop to roll under) put soft rags on the floor and drape another one loosely over the work prior to the point at which the part is likely to release.
The link you posted to the Fox Oil Volume Charts doesn't have the data for 2019 36 grip2 fork, do you have a link? i can't find it and if i could, i'd be grateful for someone confirming it. keep up the great videos.
Mate, I love the level of analytical detail you have in these Mechanic Monday videos. Keep explaining not just the how, but the why and you’ll have a 100k subs in no time!
Destroyed both foot nuts trying to hammer them out. FUBAR. Serves me right for getting the bike in 2018 and not servicing them once. Off the to LBS I go $$$$$
I'm a motorcycle mechanic and don't thrust just anyone to work on my stuff but you, i'd let you! you know your stuff AND your special care and attention to details is right up there!. How old are you???
After 5 years, this remains by far the best video on rebuilding Fox 36 forks. Have watched it several times while servicing my bikes. Today's feat included replacing the original Fox 36 Rhythm fork on my 2023 Specialized Levo SL with the new Fox 36 Factory fork I recently got from you. Then, I decided to rebuild the Rhythm for future use...and found that its air spring was way over-greased as this video had shown. Thinking back, I believe that virtually all of my suspension parts and related tool purchases have come from The Lost Company. TLC always seems to have the best Fox and SRAM parts inventory and pricing. You certainly have a fan here! Now, what to do with all of these used shop towels?
Very interesting and well done video. I only have one question about the GRIP2 service: the official FOX video (like other tutorials) indicates to push the cartridge rod upwards for 3/4 of its travel in order to release the excess oil. In other videos some don't. By pushing the rod up so much, wouldn't you risk letting too much oil escape from the cartridge? However, I suppose it is used to avoid adding oil to the 40cc PTFE already included in the FOX reference table. Thank you so much! K
Hey, great video. I want to buy the GRIP2 Upgrade but having trouble finding it for sale in Europe. Can you confirm what the Fox part number for the 2021 upgrade kit is? Cause the one I'm seeing seems to be the 2019 one. EDIT Nevermind I found it. It's 820-18-335-KIT for anyone who's also searching. I can buy it directly from Fox in Germany, if you're in the US I hate you because your prices are so much lower haha.
Fair play you're really awesome at what you do...!! I thought I was a perfectionist but you make me look sloppy!!! If I was ever getting my fox 36's done I'd want you to do them!!👏🏻👌🏻
per Fox torque specs for tightening footnuts: dampener side = 9.0 Nm; air spring side = 5.7 Nm. Also, air spring top cap needs non-beveled (chamfered) 32 mm socket (Fox sells this); add 3 cc Fox suspension fluid or 20 W gold; retighten to 24.8 Nm.
Is the flat shaft where the rebound knob goes supposed to move up and down or is it supposed to be stuck in one place? When i take my two pink knobs off, i can pull the shaft up and down maybe 1/8th of an inch
So is o-ring replacement enough on the airspring? O since they're inexpensive, just change them out? Do they eventually wear out? Also, is it correct to send the Damper out to Fox every third service to keep that going strong? Great vid, I watch it every time I do fork maintenance.
BRO! This must go to my top5 internet moments ever! Thanks. There's no, however, how-to video for the Float DPS rear shock maintenance and the internet needs it! Loved to see that.
Everybody knows that ebike specific forks (Fox ebike 36) has the internals of 34 forks because of the stiffer stanchions. Can then someone reply how on earth there are Fox 36 ebike 180 and 170mm since the maximum air shaft of 34s is 160mm??? @The Lost Co. or anyone else could you please advice???
Hey, I know it’s been some years but I have a question, I’ve seen some people removing the valve core and putting oil in it. What is that for? And, do I have to do it on my fork? (Fox 34 2017) (Sorry about my English)
So I have a 2020 Yeti with Fox 36 FIT4 and this would be a good upgrade? I figure when I'm do for the fluid change maybe I'll do that....thanks for the video!
I've watched heaps of lower leg services ready to do it myself. I would say I would have been guessing until I saw this video. Amazingly helpful. Great work dude!
Great video for Fox fork servicing. The grease on the upper seals as well as removing excess on grease on the Air Spring make a huge difference to how responsive a fork can be. Unfortunately from the factory and with many shops - this is neglected and fork small bump compliance performance suffers as a result.
$1000+ on a fork and you have to deal with a slob of grease impeding the normal function of the fork. Just purchased a new Kenevo and now have to deal with a fork that doesn't get sag and cannot equalize.
Hi. I poured 40cc of ordinary 5wt suspension oil instead of fox ptf 5wt infused to the damper side and the fork feals bad. Should I remove the wrong oil from lower leg only or take the damper out and clean it all? I don't know if oil from lower bath mix with the oil in cartridge??? I have 2021fox 36 rhythm fit grip.
Can you elaborate more on how and when to add the 3cc of oil to the positive air chamber? This might be why it feels like it’s sticking? Also the bottom high and low rebound knobs won’t turn independently of each other. If I turn either one they both turn. I didn’t change to the grip 2 damper because the fork already had it so I didn’t do anything with the damper side. And trying to turn the knobs individually I may have stripped the threads so can you help me get a replacement? This is a job for a friend so I need to fix this. I would really appreciate any help. Thank you. And thank you for the great detailed video!
Each lower legs had 2 inner glider. Maybe with PTFE surface, I donť know. Is it necessary to put oil between these gliders of the lower leg? Or how is upper glider lubricated?
Best fork service video I've ever seen. Nice! Keep up the good work. I'm looking forward to my Grip2 arriving and getting it on my fork. I really appreciate the work you put in to make this tutorial.
I want to give my Fox F100RCl from 2006 a major service. but can you tell me exactly what is meant by damper side oil bath spring-side oil bath and air chamber. Am i right that the air chamber is where the airpump is mounted on the top of the left fork. Spring-side bath oil put in the underside of the left and right fork and the damper side the top of the right side fork put in?? I had seen several youtube films but now i am confused. And this ifo i have from the fox side. Best regards and thanks for the effort. Greatings from holland
You just cleared up so much for me. I feel like I now have the confidence to do this myself. I've got the tools and parts to bump up the travel on my grip 2 fork to 150. Just need the 5 wt oil now. The guy at my shop said to just use the gold in both sides, but after some investigation and watching this video I'm going to hold off until the 5wt comes in.
i noticed that RockShox forks require very little oil in the lower legs... the 36 uses TWENTY TIMES more oil than the lyrik on the damper side and 5 times more oil on the air side. isn't such a little amount of oil going to make performance worse?
Hi, for a RockShox Upgrade, you Upgrade the airspring and the damper. For the fox, only the damper. Does this mean the Performance fox already has the same damper as the Elite or factory?
I have a 32 Float SC Performance. I had to fit a new Star Nut so I had to remove Fork from my bike which included me removing the Grip3 remote connection. Anyway it was fiddly trying to refit the remote and set up correctly, during this process I lost a little oil from the top damper (as it unwound took much and popped out) It is setup correctly now and I get lock out which is all good but I’m a little worried about the oil I lost, it was only about 5ml but do you think this is ok?
Why hasn’t fox changed their QC, they still over grease the living hell out of the air springs even on the $1,200 forks. I’ve had my fork for two months and now I can’t ride.
My Fox 34 ctd needs more pressure after service than before. It took 50 psi before and now it needs 70 to be fully extended to 160mm. When I go down to 50 psi the stanchions hide in the lowers a few milimeters.
I just watched Jules do a lower leg service on 2021 fork and in comments Jordi says use 20wt oil for foam rings on air side and 5wt ptfe oil on damper side foam ring... you used 20wt on both foam rings. Can you comment on this discrepancy
Slickolium might be cheap for you guys in the states but is bloody expensive over here 🇬🇧 given the price fixing deal with sram butter or slick honey so the those brands can keep their profit and they ain’t cheap either 😡 Great video though thankyou
Hey, i took a small spill today and rubbed my 36 stanchion on hard packed loose dirt. There’s no burrs but there are like rub marks/scratches. Nothing really that my nail digs into when sliding over them. Is that something that should cause concern?
Great tutorial, thank you. Question regarding the oil on the foam ring for the damper side. I have a 2021 Fox 38 that has the channels that brings oil up from the lowers and puts oil onto the foam rings. Would you not want to use the Teflon oil on the foam ring on the damper side, as there will be more Teflon oil being brought up to the foam ring. I don’t think you want to mix the oils. On an older style fork without the channels it probably doesn’t matter. Your thoughts.
I noticed you saturated both foam rings with only one type of oil, but doesn't each side of the fork take different oil. I know you said that's ok, but I did notice that my old foam rings had different types of oil (one was saturated with the red stuff and the other was more yellow) -> I'm assuming that means they were saturated with the two different oil from the factory.
This video is much better than everything, that I saw till this moment for that kind of service. Even better, than FOX original videos - they are too poor. Great! Thanks, dude! Now, waiting for the X2(2019) service. ;)
Didn’t read all the comments so my apologies if this was discussed. What about the oil in the damper itself? Does that mostly stay in and is never serviced or does it slowly mix with the oil in there and slowly get changed that way? Thanks for the extra help over the Holiday with my last minute order and not so patiently waiting for my Grip2 to arrive. 😅
Great Video! Super informative and helpful and entertaining! On top of that, I couldn't agree more on your habit of keeping all the parts in the right order and constantly making sure everything is tidy and clean!!! It just makes your life sooo much easier! I am learning the craft of bike mechanic myself (Spezialized concept store... I love it!) and constantly trying to get my colleagues to develope that habit... ;) Loving your videos! Keep up the great work!
Great video. The thought of this job made me a bit nervous but after watching this, I am confident it's not a problem at all. And maybe I'll even stay organized...ha. Thanks. Do you guys do a DPX2 overhaul video?
Glad this video gave you the confidence needed! We don't have a DPX2 video as of now, but doing that and the X2 has been on our list for a while. Hopefully we will get 'er done this winter.
Thanks for your ability to clearly explain this process. You are so detail oriented and precise. Love it. I’ll be watching more of your tutorials for sure.

Sage

Hey. Can I use sram butter instead of a slickleum?
Probably they are pretty much the same thing.
Just doing the service right now. Don't you have to use the fox gold on the foam ring on the air side and the other oil on the foam ring on the damper side?
To add the 3 CC oil after reassembling, can I just let the air out, remove top cap and pour it in without having to take off lowers? Thanks.
Daniel Kaplan I did. Seems to be working normally.
Soak your rings over night and stretch them a bit behind dropping them in or else you will tear them.
Question: The Fox document with all the oil types and capacities, lists 3 cc of 20wt oil in the air chamber. But you didn't do that in this video. Should that be done? If so, where/how exactly do you add that oil?
Yes, unfortunately this part got lost in editing. The service guys at the shop will take a fingertip full of Slickoleum and a fingertip full of Fox 20wt Gold oil and swirl it together in the air chamber on top of the air shaft piston.
Didn't you just cross contaminate the 5wt PTFE fluid w/ the 20wt Gold by soaking the foam rings on both side w/ the stuff?
yes he did
Can slick honey be used in place of the slickoleum on the NA2 o-ring and shaft, and on the dust wipers? I have this already.

Hey, great video. I want to buy the GRIP2 Upgrade but having trouble finding it for sale in Europe. Can you confirm what the Fox part number for the 2021 upgrade kit is? Cause the one I'm seeing seems to be the 2019 one.
EDIT Nevermind I found it. It's 820-18-335-KIT for anyone who's also searching. I can buy it directly from Fox in Germany, if you're in the US I hate you because your prices are so much lower haha.
Fair play you're really awesome at what you do...!! I thought I was a perfectionist but you make me look sloppy!!! If I was ever getting my fox 36's done I'd want you to do them!!👏🏻👌🏻
per Fox torque specs for tightening footnuts: dampener side = 9.0 Nm; air spring side = 5.7 Nm. Also, air spring top cap needs non-beveled (chamfered) 32 mm socket (Fox sells this); add 3 cc Fox suspension fluid or 20 W gold; retighten to 24.8 Nm.
Is the flat shaft where the rebound knob goes supposed to move up and down or is it supposed to be stuck in one place? When i take my two pink knobs off, i can pull the shaft up and down maybe 1/8th of an inch

Would for example SRAM Butter work in place of Slickoleum?
Wow I cant tell you how thankful I am for putting this video up! So thorough and I feel like a pro when it comes to shocks now!
Ok, so this is why I pay so much for a specialist to do it!
So is o-ring replacement enough on the airspring? O since they're inexpensive, just change them out? Do they eventually wear out? Also, is it correct to send the Damper out to Fox every third service to keep that going strong? Great vid, I watch it every time I do fork maintenance.
Great in depth tutorial! and lots of helpful little pointers to make the work much easier. THANK YOU!
BRO! This must go to my top5 internet moments ever! Thanks. There's no, however, how-to video for the Float DPS rear shock maintenance and the internet needs it! Loved to see that.
Everybody knows that ebike specific forks (Fox ebike 36) has the internals of 34 forks because of the stiffer stanchions. Can then someone reply how on earth there are Fox 36 ebike 180 and 170mm since the maximum air shaft of 34s is 160mm???
@The Lost Co. or anyone else could you please advice???
So you soaked both foam rings in 20wt oil, but used different oil in each side. Isn't this a nono?
Loved the video; was able to get a lot of information that I haven’t seen before. Thanks again for the detailed instructions.
Sweeet! I'm stoked you both enjoyed the video and learned something! My two goals accomplished 😁
Hey, I know it’s been some years but I have a question, I’ve seen some people removing the valve core and putting oil in it.
What is that for? And, do I have to do it on my fork? (Fox 34 2017)
(Sorry about my English)
So I have a 2020 Yeti with Fox 36 FIT4 and this would be a good upgrade? I figure when I'm do for the fluid change maybe I'll do that....thanks for the video!
I've watched heaps of lower leg services ready to do it myself. I would say I would have been guessing until I saw this video. Amazingly helpful. Great work dude!
Great video for Fox fork servicing. The grease on the upper seals as well as removing excess on grease on the Air Spring make a huge difference to how responsive a fork can be. Unfortunately from the factory and with many shops - this is neglected and fork small bump compliance performance suffers as a result.
$1000+ on a fork and you have to deal with a slob of grease impeding the normal function of the fork. Just purchased a new Kenevo and now have to deal with a fork that doesn't get sag and cannot equalize.
Hi.
I poured 40cc of ordinary 5wt suspension oil instead of fox ptf 5wt infused to the damper side and the fork feals bad. Should I remove the wrong oil from lower leg only or take the damper out and clean it all? I don't know if oil from lower bath mix with the oil in cartridge??? I have 2021fox 36 rhythm fit grip.
Can you elaborate more on how and when to add the 3cc of oil to the positive air chamber? This might be why it feels like it’s sticking? Also the bottom high and low rebound knobs won’t turn independently of each other. If I turn either one they both turn. I didn’t change to the grip 2 damper because the fork already had it so I didn’t do anything with the damper side. And trying to turn the knobs individually I may have stripped the threads so can you help me get a replacement? This is a job for a friend so I need to fix this. I would really appreciate any help. Thank you. And thank you for the great detailed video!
I just bought a brand new FOX 36 2021 (OEM). I was told the basic (zero) service is recommended. Is this true?
PleasePlease....Make One for fox 34 factory fit4.....or IF you have any ideas where I might look for information for servicing my on fork on my own?
Each lower legs had 2 inner glider. Maybe with PTFE surface, I donť know. Is it necessary to put oil between these gliders of the lower leg? Or how is upper glider lubricated?
Best fork service video I've ever seen. Nice! Keep up the good work. I'm looking forward to my Grip2 arriving and getting it on my fork. I really appreciate the work you put in to make this tutorial.
I want to give my Fox F100RCl from 2006 a major service. but can you tell me exactly what is meant by damper side oil bath spring-side oil bath and air chamber. Am i right that the air chamber is where the airpump is mounted on the top of the left fork. Spring-side bath oil put in the underside of the left and right fork and the damper side the top of the right side fork put in?? I had seen several youtube films but now i am confused. And this ifo i have from the fox side.
Best regards and thanks for the effort.

You just cleared up so much for me. I feel like I now have the confidence to do this myself. I've got the tools and parts to bump up the travel on my grip 2 fork to 150. Just need the 5 wt oil now. The guy at my shop said to just use the gold in both sides, but after some investigation and watching this video I'm going to hold off until the 5wt comes in.
i noticed that RockShox forks require very little oil in the lower legs... the 36 uses TWENTY TIMES more oil than the lyrik on the damper side and 5 times more oil on the air side. isn't such a little amount of oil going to make performance worse?
Just a small note. You removed the foot nut before you removed the crush washer correct? ............am I dyslexic?
Thank you a lot for this excellent video! I am glad you did the proper long video.
Hi, for a RockShox Upgrade, you Upgrade the airspring and the damper.
For the fox, only the damper.
Does this mean the Performance fox already has the same damper as the Elite or factory?
I have a 32 Float SC Performance. I had to fit a new Star Nut so I had to remove Fork from my bike which included me removing the Grip3 remote connection. Anyway it was fiddly trying to refit the remote and set up correctly, during this process I lost a little oil from the top damper (as it unwound took much and popped out) It is setup correctly now and I get lock out which is all good but I’m a little worried about the oil I lost, it was only about 5ml but do you think this is ok?
Shouldn't be the oil ring of the damper side drained in 5WT oil? You drained both of them in the 20WT oil. ANSWER: 39:20 hihi
Why hasn’t fox changed their QC, they still over grease the living hell out of the air springs even on the $1,200 forks. I’ve had my fork for two months and now I can’t ride.
1. I have a Fox 34 that can't even use a GRIP2 Damper. 2. I don't even need to do a service on my fork.
Still watched the whole thing.
My Fox 34 ctd needs more pressure after service than before. It took 50 psi before and now it needs 70 to be fully extended to 160mm. When I go down to 50 psi the stanchions hide in the lowers a few milimeters.
I just watched Jules do a lower leg service on 2021 fork and in comments Jordi says use 20wt oil for foam rings on air side and 5wt ptfe oil on damper side foam ring... you used 20wt on both foam rings. Can you comment on this discrepancy
Excellent video, just one question. Fox says to fully pump before putting the lower legs, you didn't do it, why?
This is brilliant. Plenty of detail & excellent production value. Thanks mate!
Slickolium might be cheap for you guys in the states but is bloody expensive over here 🇬🇧 given the price fixing deal with sram butter or slick honey so the those brands can keep their profit and they ain’t cheap either 😡
Great video though thankyou
Hey, i took a small spill today and rubbed my 36 stanchion on hard packed loose dirt. There’s no burrs but there are like rub marks/scratches. Nothing really that my nail digs into when sliding over them. Is that something that should cause concern?
Great tutorial, thank you. Question regarding the oil on the foam ring for the damper side. I have a 2021 Fox 38 that has the channels that brings oil up from the lowers and puts oil onto the foam rings. Would you not want to use the Teflon oil on the foam ring on the damper side, as there will be more Teflon oil being brought up to the foam ring. I don’t think you want to mix the oils. On an older style fork without the channels it probably doesn’t matter. Your thoughts.
I noticed you saturated both foam rings with only one type of oil, but doesn't each side of the fork take different oil. I know you said that's ok, but I did notice that my old foam rings had different types of oil (one was saturated with the red stuff and the other was more yellow) -> I'm assuming that means they were saturated with the two different oil from the factory.
Could I send u my fox 34 factory 2016 .. is was given to me used .. don’t even know when it was serviced
This video is much better than everything, that I saw till this moment for that kind of service. Even better, than FOX original videos - they are too poor. Great!
Thanks, dude!
Now, waiting for the X2(2019) service. ;)
Thanks a ton!! I'm sure a Float X2 service video will be up before Spring!
Fantastic video. I’m trying this today 😁. Thanks for taking the time to do this.
9:45 he proceeds to milk the fork
Didn’t read all the comments so my apologies if this was discussed. What about the oil in the damper itself? Does that mostly stay in and is never serviced or does it slowly mix with the oil in there and slowly get changed that way?
Thanks for the extra help over the Holiday with my last minute order and not so patiently waiting for my Grip2 to arrive. 😅
Just found this video and after the first few minutes I thought, "this guy probably went to UBI". then I noticed the safety glasses
Great Video! Super informative and helpful and entertaining!
On top of that, I couldn't agree more on your habit of keeping all the parts in the right order and constantly making sure everything is tidy and clean!!!
It just makes your life sooo much easier!
I am learning the craft of bike mechanic myself (Spezialized concept store... I love it!) and constantly trying to get my colleagues to develope that habit... ;)
Loving your videos!
Keep up the great work!
So I would assume I could review this video for doing a fox 34, it's just a matter of looking on ridefox for the proper fluid?
Great video. The thought of this job made me a bit nervous but after watching this, I am confident it's not a problem at all. And maybe I'll even stay organized...ha. Thanks. Do you guys do a DPX2 overhaul video?
Glad this video gave you the confidence needed! We don't have a DPX2 video as of now, but doing that and the X2 has been on our list for a while. Hopefully we will get 'er done this winter.
What’s your opinion on just changing the oil in a fit4 damper yearly ? I think a full service yearly is a lot. I would do lowers and air side yearly.
Just karate chopped the subscribe button. Thanks so much for making this video!
Thanks for your ability to clearly explain this process. You are so detail oriented and precise. Love it. I’ll be watching more of your tutorials for sure.
Yall should make a video doing the newer 2021+ models
