Sealant Refresh - Stan's NoTubes

[@NicohlGeszvain-gc8ov]

Great tutorial. Mention holding base of valve stem for tightening and loosening and giving that tire some spins to distribute the Stan’s!

[@loft4me]

This is simple but very helpful. My bike has the orange stuff (I forgot the name), but surely the same principle applies. I was looking for tips on how to address a slow leak; this video shows removal of stem, and the amount of sealant to be reintroduced, which I needed. Thank you.

[@lilhavin]

So much good information from both this video as well as the people commenting. Thanks a million guys, I most certainly appreciate the knowledge!

[@notubes]

Happy to help!

[@TMick13]

I've only had tubeless tires for about six months and was a bit nervous about refreshing the sealant. Thank you for this video because you made it look easy and it was!

[@zach.225]

TMick13 is it worth the switch?

[@cyclingpickle5230]

@@zach.225 if you ride off-road then yes it is definitely worth the switch. Working with sealant and all that is a small price to pay when it means not stuffing around with tubes all the time.

[@JimboJammy]

@@zach.225 Not just for off road, but if you're someone like me who also commutes on his mountain bike, you'll be no stranger to broken glass in cycle lanes. I was getting punctures on average once a month before and was getting fed up spending my lunch hour repairing or replacing tubes. Been no issue since going tubeless. 🤞

[@MrHeepspo]

Put in 3-4oz and it will last over a year. I've been doing that for quite a while.
My current 29er tires on my Santa Cruz Chameleon have stans fluid from December of 2017 and they're still going good... changing this week though.

[@lazurm]

MrHeepspo: How do you find out if the sealant is still good?

[@lazurm]

@@TomNuts I was hoping for a less labor intensive solution. I add every 4 months without looking.

[@bimmerbent]

@@lazurm You shake the tire and listen for sealant, very simple.

[@lazurm]

@@bimmerbent Thank you.
I've been using what I believe (so far) to be a foolproof system which, thanks to my electronics/programming knowledge, seems to solve the issue.
Inspired by hearing loss I simply attach a clamp-on, cordless sound sensor and record the sounds, while the wheel is spinning in my truing stand.
Since I've programmed a home made app to interpret the sounds (based on a series of tests for sound data, with a variety of fill rates in the tire I used) I've been able to actually obtain the "drying curve" with enough precision, confirmed by observation, that I can now confidently predict the optimum time to refill. Note that when I take a "sound" I keep the tire at the same pressure as I did when compiling the data as this, too, can change the "sound".
Yea, lots of work initially but, now, easy as can be. Interestingly, for me, the viscosity of the liquid is significant in terms of the sound generated. So, I'd have to guess that each product generates its own sound as their respective viscosities vary. I'm not motivated or curious enough, though, to find out the differences in the various products but I have quite the data for the Stans product I use. :)

​@lazurm
One way if you get a puncture n it won't seal it
With green slime it gets hard n is no longer a liquid in air tubes for tires
With this stuff I don't know if it gets hard
Keep like 2 bottles on you n a good small pump n a steel valve stem remover tool when riding, just in case it is no good anymore when getting a puncture, or you just need to add some more to help seal puncture up better
Saved me a few times especially on Ebikes, ebikes are a lot heavier n harder to push back

[@chrisstrobel3439]

Just a FYI, my mountain bike has been hanging upside down in the garage unused for 14 years. The rims are regular 26” Mavic’s I converted to Stans back then. Today I decided to take the bike down to see what kind of maintenance it might need to get it running again, and when I pumped up the tires they held air! Pretty Amazing I thought. Guess I’ll top it off to be on the safe side 😬

[@notubes]

Thanks for the note Chris! Always best to top off, just to be sure!

[@JimboJammy]

Been running Stans close to a year now with no refresh. So far so good!

[@michaeljohn7467]

If you don't get any punctures, then ya your tire will be fine n doesn't matter if sealant got to old
Or maybe the weather you in isn't to hard on the sealant n it is lasting longer
Regardless of your situation, good to keep a bottle or 2 on you n a good small pump n a steel valve stem remover tool when riding, just in case you get a puncture n your sealant goes bad n won't clog it up
This saved me a few times people, especially on Ebikes that are more difficult to push back when you get a flat
This saved me many times people to get my ebike riding again

[@JimboJammy]

@@michaeljohn7467 thank you for the advice 😊

[@PittHead]

Hi thanks for the video, when do you suggest taking the tyre off and cleaning it, changing the tape etc instead of just a top up?

[@notubes]

Happy to help! The only time that it's really necessary to remove the tire is to remove any larger balls of dried sealant that can form over time. Once a year, or every time you swap tires would be a good time. The tubeless tape is not a wear item so it won't need to be replaced unless it becomes damaged or if you need to remove it to replace a spoke.

[@wt9mm]

When you say it depends on the climate, what exactly do you mean? I live in hot climate so do I refresh more or less often? How much sealant do I use on a fat bike tire refresh?

[@notubes]

In hot dry Climate the sealant will dry out quicker. 4oz for the fat bike.

[@gregfeet4269]

It also depends heavily on how often you add or remove air from your tire. Sometimes I inflate to 45 psi for a long pavement climb up, then deflate to 23 for a single track decent. Each time you remove and replace air, you are drying out the sealant inside. If you were to always keep you tires at the same pressure, the sealant will last much longer.

[@lazurm]

@@gregfeet4269 I use Stan's and top off every 3 months (I live in a temperate climate zone in New York). My tires are 38x700c. I have to inflate them every 2 or 3 days to keep them at the optimal 70 lbs. of pressure. So, though I always keep my tires at the same pressure, air can permeate through the rubber compound and sealant anyway and, I believe, that's normal.
What would be ideal would enable a sealant user to determine the condition and useable amount of the sealant without merely sticking to a refill schedule that may, or may not, be correct.

[@ThePaigeMa5ter]

How do you do it with a more classic stem, one that doesn’t allow for strait access. It has the pin that stops the air. ?

[@notubes]

Hi Will! Are you referring to a schrader valve like the kind that's on your car tires? They also have a removable core so this same refresh process will apply to those too. Just use the opposite end of the Core Remover Tool for those schrader valves!

[@tomhughes3471]

Is this how you fix a puncture in stans no tube aswell ??

[@user-ro7oq1ie3s]

Do you have to put sealant in a tubeless tire?

[@michaeljohn7467]

[@jeepman6574]

[@zwgraham]

@@absolutemtb6696 the bead usually stays seated unless you pop it out.

[@sisophous]

Good video, thanks for uploading it. But you didn't mention the size of your tube. I will be using Continental Race Road Tubes 700c x 25-32mm. BikeTiresDirect told me a 2 ounce tube of Stans sealant will be enough to fill 2 tubes but you claim it will only fill one tube? I'm not clear on this. Any feedback would be appreciated.

[@janschonander9917]

maybe late, that is because you are running tubes! this video is mainly intended for a tubeless setup

[@bansheerider619]

Umm did you read the title?

[@tmfrs2]

if the stans sealant starts to become lumpy, do you have to clean the whole inside of the tyre, or just take the lump and put some sealant again

[@notubes]

Thanks for the question. We recommend just removing the lump of Stan's. There is no need to clean the entire inside of the tire.

[@JonMcLeodMelbourne]

Replace sealant "every two to seven months depending on where you live"? So what does this mean? Cold climate needs less or more frequent refresh?

[@notubes]

Hey Milennial Zero, climates that are drier and warmer will typically require more frequent sealant refreshes. Colder climates should lean towards the later end of our recommended 2 - 7 month refresh interval.

[@MrHeepspo]

My bikes are stored in a 90-100 degree garage when I'm not riding them during the Summer. We live in an area with very dry hot Summers... I use 3.5oz in EACH of my 29er tires. This is the trick, IMO. Put more in than they say. The local bike shop does this... so I took their advice and it's been amazing!

[@lazurm]

@@notubes I'll guess, though, that the native climate doesn't matter much if one stores their bicycle inside a climate controlled environment, riding from 2 to 6 hours each week. What would the recommendation be under those circumstances?

[@notubes]

@@lazurm Refresh intervals can still vary based on other factors too. It's still a good idea to check your sealant levels every couple of months.

[@lazurm]

@@notubes Besides physically removing the tire to look at the sealant inside (not fun and too laborious) what is your recommendation for checking the sealant levels, as you advised?
I find that adding 3 ounces every 3 months solves the "checking" problem but, can I be incorrect?

[@iccullen]

Just wonder if the bench mat is available or any recommendations?

[@notubes]

Hey Ian! Unfortunately, there are only two of those in existence right now. They are super nice, so maybe it's something we'll consider in the future!

[@iccullen]

@@notubes Fingers crossed! One would look well on my work bench. Handy for sealant spills :-)

what's should i use to clean the inside of mt tyre to remove the existing sealant..? - I've used one lot of sealant in there (March), so ok to just top it up and do a complete clean of the tyre around xmas time?

[@notubes]

Hello! No need to completely clean the inside of the tire. That layer of dried sealant is actually helping to seal the casing of the tire. Just pull out any large pieces of dried latex and top off with some fresh sealant!

[@himalayandirt8486]

Hi I have used a different brand sealant in the tyre and it’s been dried out. Now I have to add sealant again, can I use a different brand? Im going to put stans no tube now. If yes then should I clean up the tyre with the lump inside or could I just inject through the valves? Thanks

no

[@walleyvideo8297]

I just bought 3 bottles for my Rad Runner. Should I wait for a flat to use a bottle or inject it now? Thanks for the video.

[@notubes]

You can absolutely add that sealant now. It will stay liquid inside the tire and seal any punctures that you may get in the future. You will eventually need to top off your sealant levels as it dries out, typically every few months or so.

Hey System32, it is not necessary to remove dried sealant from your tire, but large areas can be peeled away by hand or scrubbed away with a stiff brush.

If you just keep adding new sealant every 2 to 7 months doesn't that keep adding more and more weight to the tire since the old sealant is still in there?

[@jeffreymirsepasy3700]

What a bullshit video!!! The tire STAYS ON and doesn't LOSE ITS SEAL? When does THAT ever happen!!!

[@ForceBuilt]

This is not to keep the tire from loosing the bead seal. This sealant refresh is because the sealant will dry up over time. People will want to refresh the sealant, so that when you get a puncture on the trail, there will be liquid in the tire to seal the flat before all the air escapes. P.S. I have tubes. Why? Swapping from trail tires to hwy tires 8 min and no mess.

[@jeffreymirsepasy3700]

FuturaForce My comment refers to the video where it looks so easy, but in reality the tire usually pulls off the beads and you no longer can put air in it on the first try, even with a charger bottle filled to 160 PSI.
