Stans No Tubes Race Tyre Sealant - Quart
If you've walked the mechanics' pits at any National or International level event, chances are you've seen them: trademark Stan's black quart bottles with no labels. Look closer and you might have seen strange symbols scrawled all over the bottles in a silver marker, letters and numbers, formula notes by the man himself, Stan Koziatek.
For nearly fifteen years Stan has been quietly formulating a special racing version of our legendary sealant for many of cycling's most successful teams. Working with athletes who push themselves and their tubeless systems to the absolute limit, we've developed a proprietary sealant formula with close to twice the amount of our standard sealing crystals plus our special "XL" crystals capable of sealing even larger punctures. Stan's Race Sealant's combination of large and smaller sealing crystals interlock to form a lattice work that not only seals but strengthens and reinforces the area of the puncture, allowing for an entirely new level of sealing performance.
This is the next level in sealing power from the people who invented tubeless conversions and made tubeless readily available to the masses. The quantity and size of crystals in this special formula means that Stan's Race Sealant can only be installed directly into the tire. As a result of its immense sealing capabilities, the Race Sealant will clog injectors and smaller bottles almost immediately.
We are now making our Race Sealant available to riders everywhere. Stan's Race Sealant is only available by the quart.
  • Ride the widest range of conditions and temperatures - Premium low-viscosity latex coats the tire’s sidewalls for quicker sealing 
  • Faster and better sealing capabilities to keep you rolling - Twice the sealing crystals compared to the standard sealant 
  • Seals larger punctures to get you home or to the finish line - “XL” crystals and standard crystals combine to seal larger punctures 
  • Safe for the environment - Comprised of natural materials
Mr WardEasy set up and took some abuse on a mtb race
Mr SankauskisUsing this for mtb and road ,works everytimes then needed
Mr burgesshave used for a couple of months now. been quick sealing the 2 small holes that i noticed , not had an issue otherwise. wld get again
GrahamUsed for last 18 months , no problems🤞
Mr AspreyStans No Tubes race tyre sealant may be expensive but is the best on the market in my opinion . i ride rocky desents like Antur Stiniog & havent had a puncture yet. i would recommend this product.
Mr HodgsonIt's good sealant. It has dealt with punctures better than others I've tried.
Mr ShireTopnotch product worked a treat first time happy with my purchase 😁👌
Mr SherwinBest stuff on the market.. fast delivery and great price. Thanks again
JordanFirst time I've used this and it was fairly straightforward. Added 90ml per wheel and the tyres seated immediately with use of the Schwalbe Tire Booster. No loss of air or any other issues in a few weeks of riding.
leeI researched sealants, and found this product to be consistently in the top 3. Great price at Merlin Cycles.
Mr CarnellGreat sealant! Just be careful, it's the race formula so you can't add it via the valve or it will clog, best poured into the tyre.
SamThe obvious choice. No other sealant comes close. Have tried finish line, schwalbe, Stans original and none seal as well.
Mr lloydI have used Stans sealant for many years in my MTB's and commuter bike and never had a problem,, I expect this product to be no different. No puncture's as yet.
Mr Smallwoodwell this fixed a persistent leak (probably tape leak) where other sealant hadn't.
Mr RichardsService and delivery was very efficient, product as always just works :-)
PeterEasy to get the tires tubeless with this sealant.
BuzOnly use this for sealing tyres. Excellent product. Never failed me on the road.
Mr MYAZKThe seal performance is outstanding.
E. petersonBest product I have used to stop leaks fast
Mr Glass NielsenI have tried many types of sealant and must say that Stans this probably best I have tried
Mr Brookesgood sealant, tires pinged on no problem
Mr greenPaid the extra for the race sealant as is supposedly much more efficient, does appear to have a lot of crystals upon application but yet to puncture, so time will tell.
MikeWorks well, It should be noted that race sealant won't work with syringe.
BARRY DIMELOWUsed a few differing sealants for road use and I have had most success with this one . Highly recommend.
PhilippDifficult to fill into the tire as you can't use a syringe or remove the valve core. Plus they tell you to invert the bottle when filling the tire which will cause a big mess. Does seal well though.
Mr san pedroExcellent product. Price to performance compared to othe tire sealants stans race sealant passes my expectations
NicholasNo punctures, so can't comment on effectiveness of this product, but did a nice seal around the valve stem
neilReally good sealant
Mr CExpensive, but Stan's stuff just works. Been using Stan's since 2004 and see no need to change.
Mr MillsI haven't had a puncture so far, at least, not one that I have noticed.
DanielSealed my tubeless setup well, can't speak for puncture protection yet.
nelsonFirst time using this variation of the sealant. Interestingly as I inflated the tyre it immediately sealed 3 punctures and maintained them on a 40k off road ride too. Given 1 of the punctures was right next to a grip block I was pretty impressed - other sealants have failed in such positions.
Qwiso WhizzoBest price I could find, and at only slightly more than the normal stuff, I figured I might as well give it a try. Be aware that you can't inject it into the tyre in the normal way, as it would clog your valve because it seals so quick - my initial concern about it clogging the valve if left valve-side down proved unfounded, as it still allows the tyre to inflate and deflate as normal after several weeks. Improved puncture sealing also adds greats confidence to my riding.
BroughBetter choice than standard sealant if you run plus tyres over rocky terrain as you are gonna need all the gloop you can get to plug tears.
Mr MaginnThis sealant is a bit thicker/ more granular than standard Stans so needs to be poured directly into the tyre rather than using the injector through the valve. No punctures yet! I got this because I had two holes in the previous two weeks that Stans didn't seal & needed to put a tube in on the trail.....messy! Hoping this works better. It's expensive though.
Mr FelsteadThe best tubeless sealant out there! OK it costs more but it definitely works.
RothwellEasy to install, but no flat tyres yet so hard to say if it works better than standard sealant!
