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.
 
Features:
  • 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 MYAZK The seal performance is outstanding.
E. peterson Best product I have used to stop leaks fast
Mr Glass Nielsen I have tried many types of sealant and must say that Stans this probably best I have tried
Mr Brookes good sealant, tires pinged on no problem
Mr green Paid 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.
Mike Works well, It should be noted that race sealant won't work with syringe.
BARRY DIMELOW Used a few differing sealants for road use and I have had most success with this one . Highly recommend.
Philipp Difficult 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 pedro Excellent product. Price to performance compared to othe tire sealants stans race sealant passes my expectations
Nicholas No punctures, so can't comment on effectiveness of this product, but did a nice seal around the valve stem
neil Really good sealant
Mr C Expensive, but Stan's stuff just works. Been using Stan's since 2004 and see no need to change.
Mr Mills I haven't had a puncture so far, at least, not one that I have noticed.
Daniel Sealed my tubeless setup well, can't speak for puncture protection yet.
nelson First 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 Whizzo Best 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.
Brough Better 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 Maginn This 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 Felstead The best tubeless sealant out there! OK it costs more but it definitely works.
Rothwell Easy to install, but no flat tyres yet so hard to say if it works better than standard sealant!
