Stan's No Tube Preventive Liquid Tyre Sealant

Product Information

Effetto Mariposa's Végétalex Tyre Sealant is quite different to anything else we've used. It's got a gloppy, almost oily, gelatinous consistency to it, which is a result of its plant-based ingredients – it's fully biodegradable and totally plastic-free. The quantity and size of crystals in this special formula mean that Stan’s Race Sealant can only be installed directly into the tyre. As a result of its immense sealing capabilities, the Race Sealant will clog injectors and smaller bottles almost immediately. Stans are now making their Race Sealant available to riders everywhere and is only available in 32 oz. Quiet Formulation After switching sharp implements, he reinflated the tyre to 80psi. Between sealants, Will cleaned and patched the tyre. Stan's No Tubes Race sealant is available in just one size, 946ml, (Quart in US Imperial) and there are some bold claims, including that it will seal punctures “faster and better”, and has twice the particles compared to the standard No Tubes sealant. The sealant uses XL crystals as well as the standard-size particles in the Race version to give better sealant protection - and it should be suitable for use in a wide temperature range, although no exact figures are provided.

Race formula is only available in bigger tubs (just under a litre for just over thirty quid), but the extra price over No Tubes standard sealant is worth it since it’s worked extremely well for us on multiple occasions; plugging big holes fast before we’ve lost all air, which is something that rarely happens out on the trail with other sealants. We are now making our Race Sealant available to riders everywhere. Stan's Race Sealant is only available by the quart. Stans No Tubes tyre sealant really is a classic and perhaps one of the best-known options out there. The claims of cold weather performance are quite exceptional for this sealant – not many state that they'll go down to lows of -30°F / -34°C.It doesn't have fancy qualities like the Silca or Muc-Off sealants; With its milky consistency, the LifeLine sealant looks like what you might call a 'normal' sealant, like that from Stan's or Orange Seal (both also on test). But in spite of that, the LifeLine sealant still performed better than most on test. Then pump to your riding pressure. A tubeless setup should normally be 10-15% lower than the tyre pressure you use if running inner tubes.

For many sealants, this means that the life expectancy is shorter than you might realise. It’s the one aspect of a tubeless setup that can catch many riders out. How long will a sealant last? If you're going to be far from home and calling out the broom wagon isn't an option, carry tyre plugs or a product like Zot! or Stan's Dart to help deal with larger holes. As a last resort, it's worth having an inner tube with you that you can swap in if all else fails, although the sealant will make this a messy business. The best way to think of tubeless sealant is as the lifeblood of your tubeless system. Its primary job is to plug puncture-causing holes by coagulating or, keeping the blood reference, by clotting. The best tubeless sealants form a seal that will ensure the tyre remains airtight.Essentially, the Muc-Off No Puncture Hassle Tyre Sealant sits bang slap in the middle of the Silca Ultimate sealant (more effective but more expensive) and the Lifeline Tubeless Tyre sealant (less effective but cheaper). So, in terms of the actual sealing ability the Regular sealant is in line with most of the sealants we had on test. It's the claimed temperature rating and longevity that let it down. Stan’s No Tubes Race tubeless sealant comes from the brand many would agree is the most well-known proponent of tubeless bicycle tyre use. No Tube’s produces two versions of tubeless tyre sealant, with the Race version tested claiming to seal larger punctures, and this may be true but other areas of the performance severely limit the overall appeal in the highly competitive best tubeless sealant space. Although the sealing ability isn't quite as good as the two sealants before it, the LifeLine Tubeless Tyre Sealant is still a sealant we can highly recommend as it's incredibly good for the price. Silca's Ultimate sealant launched in early 2022 and came with a raft of innovations and bold claims – notably an ability to seal punctures up to 6mm at 80psi and up to 8mm in lower pressure systems. Impressively, it has gone and lived up to the hype.

There definitely is something about long stranded particles that really boosts sealing performance. Although Silca has made a lot of fuss about its carbon fibres and its research, it appears that the Muc-Off sealant works in much the same way, with very similar-looking fibres visible in the plugged holes. Still, 6mm is a very good performance – better than any of the other sealants we tested except Silca – and especially at these higher pressures we tested at. Therefore, we performed comparative tests in our workshop, controlling the variables as much as possible.

In the event of a puncture, locate the source and rotate the wheel until it is at the lowest point to enable the sealant to begin the process of plugging the hole. Then rotate the wheel until the puncture is at the top. This will allow the air to get to the sealant and enable the sealant to begin coagulating and plugging the hole. If it still leaks air, repeat the process until it works. Pirelli says the sealant works from 15 to 100psi pressures and in a range of temperatures from -20 to +70 degrees Celsius - and we found that it lasts very well without the need for replacement.
