Tubeless sealant of the highest level. The NoTubes Race Sealant comes from the same people who've created tubular bike tyres in the first place! Over the last 15 years Stan Koziatek, the owner of NoTubes, has secretly been working on a racing-specific formula. Working together with top-athletes, they've pushed tubeless wheel systems to the very limit. By adding different, larger, and more crystals to the sealant, it can now handle unparalleled stresses.

The NoTubes Race Sealant offers optimal puncture protection for all tubeless and tubeless ready mountain bike tyres. The sealant stays in its liquid state for longer; depending on the conditions at least between 2 and 7 months. The sealant works in temperatures as low as -35 degrees Celsius and is environmentally friendly.

In short: the ultimate sealant for running tubeless. Trouble-free use of the Stans NoTubes Tyre Sealant in all tubeless ready mountain bike tyres and wheels. Also works with all inner tubes fitted with a removable valve core.

Super sealant, beste op de markt!

Perfecte sealant om je tubeless wielen te complementeren. Na een klein lek zoals doorn, sneetje, gaatje, dicht de sealant het lek.


  • Dicht perfect
  • Handig in gebruik
  • Duidelijke beschrijving


  • Prijzig voor de hoeveelheid

Direct gaatjes gedicht

Had binnenbanden en die eruit gehaald. Toen ontdekte ik dat er al gaat es in de band zaten. MTB banden maximaal opgepompt en gaatjes werden keurig gedicht


  • Werkte direct bij tubeless maken

Beste wat je kunt krijgen

Dit is de beste sealant die je kunt krijgen: kost wat maar is in staat op grotere gaten van 4 mm + te dichten. Na een vakantie in Engeland met veel bramenstruiken over gestapt op tubeless. Toepassing is erg eenvoudig, geen lekke banden meer en je kunt met lagere spanning rijden.


  • Makkelijke toepasbaar
  • Lekdichtcapaciteit beter dan de rest


  • Duurder dan de rest

Met deze Sealant lukt het je wel!

Heel erg tevreden over deze sealant. Waar ik eerder een kilometer of 170 moest rijden voordat ik de X-King RACESPORT dicht kreeg lukte het met STANS Race Sealant in één keer! Ook na lek rijden is het gaatje snel dicht en kon ik gelijk door zonder dat ik lucht hoefde bij te pompen! Andere sealants doen gewoon niet wat ze beloven al ben ik ook benieuwd naar de Muc-Off Sealant


  • Deze doet dus wel wat het belooft!


  • Prijs (maar neem ik voor lief)
  • vaker bijvullen dan andere sealants
  • kan gaan vlokken als je de bus te warm weg zet

Manufacturer description

The Next Level in Sealing Power from the People who Invented Tubeless Conversions
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.
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.
