Stan's New Race Sealant - Review

Feb 15, 2016

Stan s race Sealant 2016


Stan's NoTubes announced a number of weeks ago that the company had founded "Stan's Racing Development division," and along with it came two quarts of SRD's first official product: "Race Sealant." The formula had been used in various forms for years, and was reportedly shipped to race teams in black, unmarked containers. Race Sealant is based upon the exact same latex fluid as the original, but it uses a mixture of large and small irregular-shaped particles that interlock more quickly and can seal fairly large punctures instantaneously. Information on the quart sized container warns that the Race Sealant must be poured into the tire directly. It cannot be injected through the valve stem and it will clog just about everything. (So, keep your valve core at 90-degrees when inflating or deflating air pressure). The official word is that Race Sealant will remain liquid as long as the original, both in the can and in the tire, and that it will function at temperatures as low as - 30 degrees F (- 34 degrees C). MSRP for a quart bottle is $39.00 USD. Stan's NoTubes


Trail Test

After watching a local sales rep' run a ball point pen into an inflated tire a few times, I was suitably impressed that Race Sealant could patch a larger sized hole than your typical nail or cactus thorn. What impressed me more, however, was that the tire was still at a rideable pressure after two stabs with a Bic pen. At home, I mounted a pair of brand new Maxxis High Rollers, poured in 2.5 ounces into each 2.3-inch tire. (That is over one ounce less than Stan's recommended dose, but I was told by a pro race mechanic that they were using half as much of the Race Sealant and getting better results when compared with the original.) The choice of tire was because the rough bead design of the Maxxis tire makes it one of the more troublesome to mount up tubeless. Aaaaand, the High Roller was still troublesome - but less so than I can remember, and when it did pop into place, there was no bubbling at the bead interfaces, no weepy pinholes in the carcass, just a well mounted tire, ready to rock and roll.

I inflated the tires to 30 psi, using my Schwalbe digital gauge, and proceeded to punch some holes with a 16-penny nail (about 3mm diameter) - four in each wheel. After each puncture, I spun the wheel a few revolutions, but one time around was all the tire needed to seal. Afterwards, I measured the pressure and it was very close to 29 psi on both tires. I'll call that a win for normal puncture sealing. Next, I lowered the tire pressure to 20 psi (front) and 22 psi (rear) and pounded some speed runs down the rock gardens on my favorite test loop, hoping to do some sidewall damage. I managed to find two places where the sealant wept through the tire's sidewall, but there was no appreciable drop in tire pressure. The tires remained flat free ever since and typically stayed within two psi of their original inflation pressures for a number of days in storage. A check of the fluid inside the tires revealed that the sealant is behaving like the original and was not coagulating prematurely.

Stan s race Sealant 2016
The new Race formula is visibly thicker, but seems to last at least as long inside the tire as the original Stan's Sealant.


Pinkbike's Take:

bigquotesForty bucks for a quart of tubeless sealant is sure to raise some hackles, but for racers, the price of a flat, or the time penalty for nursing a soft tire home is far greater than paying an extra $15.00 for the quicker sealing response that Stan's Race Sealant offers. I'd recommend it for anyone who competes on tubeless tires. The Race formula may be a lighter-weight option for plus, or fat-bike tires and it's strongly suggested if you are "That Guy" - Mister Stylish SoHandsome, the rider who carries nothing but good looks to repair or inflate a flat. - RC

 I was sitting on my own at a trail head tuning up my gear with this amazing new latex "for extreme conditions", when I saw a beautiful woman riding straight towards me. She stopped and asked what I was up to. I explained that I was about to test out the most expensive latex on the menu. She grabbed the latex and replied “I'm not touching a drop unless you can assure me that you have seven inches in your pocket.” I shouted back, “Give me the latex. As gorgeous as you are, I'm not cutting off three inches for anyone.”

 Also, Stans should figure out how to get their peasant sealant not to clump and dry out in 2 months. The stuff works well when fresh but over even a few weeks I have it dry out. And yes, I follow the directions and his little youtube video.

 Here in hot/dry SoKal(it's been pushing 90 degrees for the last week), I've noticed Stan's(it's all I use, thus it's all I know) doeS seem to evaporate and coagulate a lot quicker than they say it should.
The last set or so I used it on, I used 4oz in each tire(29" Schwalbe HDs, 2.35" on Fatties= 2.5" wide), and I wanna say 3 or 4 weeks later when I went to install 'mud' tires(after a couple days of rain, it was looking like El Nino was here, but in reality he was just jerking my chain) my 4oz had been reduced to literally ZERO.
Still, I'm gonna keep using it, although I'm thinking it's pretty spendy as it is, so $40/qt is more than I wanna spend.
Maybe I'll just pick up a tube of that dry glitter-looking crap auto parts stores sell as radiator sealant, and mix some in with my 'cheap' Stan's, and see what happens. Although I had a particularly nasty thorn punch,I dunno...maybe an 1/8" hole in my tire, and while I lost 20psi, and had to spin the tire several times to get it to seal, in the end it DID seal that sized hole.

 Had a customer once mix Stans and Slime... it smelled like vomit and the looks of it made you want to do so as well but it seemed to work. He only brought his bike in when he wanted to change tires after they wore out or wanted something new and claimed he never changed the concoction.

 I use a mix of stans and slime with a little bit of washer fluid to make it last longer. Can't say it last longer than stans alone but it does seem to seal holes better

 Word of wisdom. Do NOT blow a tire off the rim if you have added glitter. I had a bead give way at about 35 PSI when mounting a tire. My garage looked like a preschooler shot glitter and Elmer's glue all over...

 I use glitter in 3 different sizes in homemade sealant. Works ok but its very cheap, as am I.

  • + 0
 @MmmBones I was just curious the effect the chunky additive has on the sealant. Stans has some latex microparticles, how does adding glitter or even organic material like oats improve the sealing properties? Is it able to patch up bigger holes than the normal stans fluid due to the larger chunks? If so, seems like a no brainer to add some extra material
  • + 1
 @kylemcnulty23 Yes, exactly. The liquid latex makes it thicker by adding more latex, so it's not sloshing around but easily coats the inside of the tire. The 8 minute steel cut oats are chunks of various size that obstruct punctures or leaks, they also make it a little thicker and amazingly, they don't clump or stick together. I imagine the minute rice would be similar, but it won't make you 7 minutes faster. Big Grin

 I had two punctures this year, both 2-3 mm punctures/tears in the centre of the tires (both new Bontrager XR2s mounted on the rear of the bike). Despite having added more sealant than recommended, and having renewed the setup about a month before, Stan's didn't seal them. Frown

 Stans has sucked for a while now, I agree that it doesn't seal the smallest holes anymore. It is sort of a joke, I use it to seal the tires but don't expect it to seal small punctures anymore, because it never does.. I know too many people that have lost their faith, constantly putting in tubes and laughing at how much of a waste of time the white ghost liquid is... perhaps this is the old formula that used to work flawlessly. Added flakes? Sounds suspect.. This eco friendly stuff we all have been using recently is GARBAGE, the stuff in this article is probable the original stuff that works...just re-branded because they know they eff'd up.

 I've had a great experience with Stan's so far. I ride in the desert where there are a lot of sharp rocks, cacti and other plants with thorns. At the end of each ride I can see where the sealant has sealed up the holes/punctures. Only have about half a bottle left, so I definitely will give Orange seal a shot.

 If you look at the way Orange Seal coats the inside of the tire when you use it, you'll never want to go back. Cleanup afterwards is easy as well. I really enjoy their stuff.

 @ze[hxii "(Orange) It's especially effective on new tire installations, specifically the ones with thin porous casings."

that's good to know because Stans can't seem to seal Conti Trail king 2.2 in the lighter version (now called Race Sport overseas) - I've had to paint the sidewalls 3 layers of Stans+Dry before mounting!. Even the heavier Protection version will seal when new, but start leaking sidewalls or wet spots in a couple months. Something about Stans eating the walls away on the Conti (which used to last forever otherwise). Also dries up too quickly for me (hot garage) and separates into funny clear liquid on the DH bike that sits around for 6+ months off season.

 1 part liquid latex from craft store, 1 part auto slime and 2 parts RV antifreeze from autoparts store. About 100 ounces for $24. I run this in three bikes, including my DH.

 Antifreeze sounds hazardous to your health brotha

 RV antifreeze is not the same as vehicle antifreeze. It's used for potable/supplywater lines not to keep your motor from freezing. It's non toxic and if it comes in to contact with your skin it won't hurt you nor if you accidentally drink it (in those cases you don't get it fully flushed out of the line).

 @DrPete Cheers, if you have more money than time! But it's only one two stores and you make enough that you don't have to buy more for a year or so. @kdstones The big secret is that these are basically the ingredients in the sealant you buy.

 You mess up on the trail with a tube, youre done unless you have a spare, which costs you 20 minutes.

 I need some opinions here. I once had mavic crossmax ust wheels with maxxis ust tyres and it was awesome, no burping at all wicked ride and feel. I changed frames and rear axle size so didn't keep mavic wheels and moved onto roval rims and specialized tubeless ready and it sucked, gave up on it after couple of months, burped lots of air, didn't hold air pressure, tyre roll etc, been on tubes since, common rear set up is maxxis ardent exo with downhill tube, flats on occasion but you know it's not a head ache, was going to try schwalbe rock razor next the heavier one, I think it's 900grams. im also waiting to see what maxxis do in reaction to schwalbe procore system. I like to slap berms hard and my previouse tubeless ready experience sucked, what do you guy's think?
  • + 5
 Well all other things being equal I'd say its specialized rim/tire or both. I run Maxis TR on Stan's Flow with no issues. Have you tried your Maxxis on the Roval?
  • + 1
 i'm now on stan's flow now so can easily try, thing is though, my ardent race has a couple rips in the sidewall I highly doubt sealant would permanently seal so the tyre would need a tube or be a throw away anyhow. it's getting worn now so will be time for another summer tyre soon.

 Yeah stay away from that specialized stuff. I used Maxis for years then switched to Continental Protection tires with stans, Really tough sidewalls and good sticky Black Chili rubber. I live in western Colorado and ride in extremely rocky desert areas; they perform, and hold up remarkably well.
  • + 1
 I run the Specialized Roval rims with 29mm internal. Don't run the Specialized valves, they suck and leak over time (I run Stan's). Also, in my experience their tires leave a lot to be desired. The rest of your issues can be applied to any tubeless setup. I'd replace the tape with Gorilla tape. I am running a Magic Mary 27.5 x 2.35 and a Maxxis DHR 2 2.35 EXO on the rear and they seal just as well as anything I've had, including Stan's ZTR rims.

 I also ran roval rims(fattie alloy) and specialized butcher grid tires and had the worst case of burping and then denting wheels. I thought running the same brand would be a good combo. Best sealing in my experience was Light Bicycle hookless with a bead hump and Schwalbe TLE. Another interesting combo is WTB TCS rims(UST profile, but has spoke holes), and their square bead UST style tires.

 Spitefully, should have named it Epic Seal for off Camber terrain and Enduro riding.

 Oh no! It cannot go through the valve ... it is a racer only product. You need to re-seat the tire every time you add sealant ....

 Well.. I dont like Stans sealant, its like "water"... I prefer slime-like sealant... Here in Chile I found one called OKO, its like oat meals with some water on it.

 I enjoy a self adhesive patch by the side of the trail from time to time. Very infrequently however, hardly ever. They sure come in handy when saving the day for some unprepared beginners, too.

 Now if this 'Pro' version can seal gashes in the sidewall *wishful thinking*, then to me it's worth the 39.00 price tag. My tires are done way before I ever need to top it off with sealant.

 Are you telling me that all this time Stan's racers have been using this sealant and he has been selling something inferior to his his customers? Sounds like a dishonest thing to do.

 Will this stuff eat into your tires like their other stuff does? Cost me two brand new Schwalbe Magic Mary's.
  • + 16
 well they were'nt going to last that long anyways.
  • + 1
 Its wasn't the sealant that ate your tires, Magic Mary's are not as strong as most would like. Were they tires that came on your bike or did you buy them aftermarket? How many square badges were on the sidewall? What was the compound?
  • + 0
 The magic mary is a softer tire derived from the muddy mary. The knobs are meant to roll and wear. Try the hans dampf for longer tread life. That said, I have seen stans eat some tires, especially anything that says it isn't meant to use sealant like for UST.
  • + 2
 They were UST. They did not come on my bike, I got them in Germany. Super gravity TL ready vert stars. I am not the only person who has seen this happen. I know that older Kenda's would fall apart. The ammonia eats the tires.
  • + 1
 glad I'm not the only one seeing Stans eats my tires as well - I have had Conti Trail King last me years on the old stans (dries up too fast IMO) but somehow lately (new formula ?) brand new Protection models would start leaking sidewalls after a few months, wet spots. Even heavy duty 2.4 TK (1000+gr) are all wet on the sides after a a year (DH bike). Some got so bad Conti replaced some for me and sent me their sealant to try. Will see. not liking Stans anymore.
  • + 1
 For me, the stans would eat into the first layer of rubber on the actual inside of the tire and then cause like a giant zit full of fluid pushing up on the knobs.

 @downhere67 , I had that happen to a pair of Magic Mary's that I had. The second pair didn't have that issue. Maybe it was a manufacturing defect? I tried to warranty mine and was given a bunch of reasons like " these waren't aftermarket purchases " and " these tire shouldn't be used with sealant " bla bla bla. I bought another pair and they lasted much longer without any deformation. The outer casing is cracking but there are still no leaks ( doubt that this has anything to do with the sealant ). this was the only tire that I had ever seen react to ANY sealant in this fashion, and I still use Stan's sealant and will swear by it. TAKE MY MONEY!!!

 @enduroelite I have now 6 tires that are oozing wet spots (Conti TK 2.2, 2.4 very badly sidewalls/thread, Swalbe Nobby nic 2.2 and new 2.25 starting a bit at knobs - those are using Conti sealant not Stans, BFT 2.4) So 6 different manufacturer. I think the sealant (and garage heat ?) is the culprit...
  • + 1
 @adumesny, Hmm, I've never had that happen, but then again I've never used the Conti sealant. Shwalbe, Conti, Kenda, Maxxis...the tire companies have never failed me when using tubeless sealant. But like I'd said, I've never used the Continental sealant..... Stan's FTW!!
  • + 0
 I meant one is using Conti sealant (that are doing better but still some small wet spots) while most of my tires are on Stans and are leaking wet like crazy...
  • + 1
 Wow, I have only seen this on:
OEM tires ( the ones that come with brand new bikes ) , Usually manufacturers will supply brand new bikes with base model tires, so you'll get a Shwalbe tire with an unusually light sidewall.
OR
Tires that predate the popularity of tubeless ready sidewalls and butyl casings.

**Try this craziness: Take the tires off and let them sit in the sun or a warm dry room so that the sealant has time to properly dry and cure to the inside of the tire. This should seal the sidewall and the leaking would stop. But i wouldnt worry about the leaking if the tire are for the most part holding air. eventually the sealant should cure and the tires will no longer sweat. Good luck!

 I tried Joes Sealant last summer & prefer it to standard Stans sealant, purely as it seals so much faster & doesnt dry up so quick
  • + 2
 Interesting that it cannot be injected. Makes some non-pro uses a pain.
  • + 5
 I've found that sealant lasts ~4-5 months before it dries and my tires are typically shredded to peices by then, so I usually only replace sealant when installing a new tire anyway.
  • + 4
 Agreed, my Stan's has lasted me at least 3-4 months and over 500 miles. At that point my tires are shot and in need of replacing. Sealant is still liquid when taking off the old tires. I've never had to add sealant after the initial mounting and have had no complaints and will definitely give the race formula a shot this coming season.
  • + 1
 Texas cacti and Mesquite thorns will drain a tire of Stans, or other liquids, in less than 100 miles. I could only dream of holding in any liquid for longer than a month, we regularly add sealant to our tires. The Race formula may help with the larger pumice, due we will still have the FOD issue.

 @macross87 Yeah I definitely don't have to deal with those tire hazards up here in the northeast.
  • + 0
 deal breaker for me - not able to add sealant through valve. I usually forgot and only add sealant back (all dried) when I get a puncture on the road. So I use a little bottle to refill, inflate (can air) and shake) then ride away without taking tire off.

 Tubeless for 13 years and counting, maybe check out a you tube DIY video. Lots of tricks there...

 Gorilla tape, 1 to 2 layers edge to edge (though not in the bead), followed by your sealant of choice. Always try to use tubeless compatible stuff but I've even seen this work with some non-tubeless setups.

 Stans = expensive....... or worthwhile investment ? Still not convinced

 There are many different sealants, Stan's is one of the least expensive. Vittoria makes one that is incredible but f*ck off expensive.

 Is this heavier than normal stans?

 I didn't realize the regular stuff didn't clog Presta valves.

 I'd like to see a rim with a special sealant port right opposite the air valve for weight distribution reasons.
  • + 2
 The valve is opposite the weld seam for that. As long as you don't have a monster valve it should be fairly well balanced. And I feel like ANY sealant will clog your presta valves.

 Meh a wise ass. Actually only a few hours, its finally drying out.
Did you have a good ride today?
  • + 1
 much better than tubes (I got 3 flats in a month trying it back due to difficult tire to seal - yes I run super low pressure on wide carbon rims) but Stans could be better. I feel lately it has eating at my tires (Conti Trail King) as they ooze wet sidewalls after a few months, and deformed 2 tires jumping. Separate into weird clear liquid + rubber on DH bite that sits 6 month at a time...
