Stans No Tubes Race Sealant (16oz / 473ml)
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.

You'll see that valve come in a variety of sizes, one solution is to measure your current valve or check out our valve guide to make sure you have the right valve for the job
Yes, you're correct! With quality tubes you have a stronger rubber so that will help, also their manufacture quality means less issues with breakages and also they don't loose pressure as easily as standard tubes, meaning more consistency and improved performance. Remember the adage, 'buy cheap, buy twice'.

Any valve cap is better than no valve cap, they keep the dust out of you valve and protected the internals. To go one step further a metal valve cap has the same benefits, increases pressure retention (incase of a leaking valve core) and look a dam sight better in our opinion if you like that sort of thing. So yes, they are well worth using.
