Stan's No Tube Preventive Liquid Tyre Sealant

Product Information

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).

If the tyre could continue to hold 70psi after the puncturing, then the next step was to repeat with the next size up – until the tyre could no longer hold 70psi without the hole reopening. The best tubeless tyre sealants are now so effective at plugging holes in your off-road tyre that the majority of the time, you won't even realise you suffered a puncture. The pros of ditching tubes and running a tubeless tyre setup are not limited to clotting and bunging holes in your rubber. They allow you to run lower tyre pressures to increase traction and grip, allowing you to ride trails faster with enhanced control with none of the risks of pinch flatting as you would rolling with a tube. Cycling Weekly sat down with founder and president of tubeless sealant maker Orange Seal, John Vargus, to find out his top tips for maximising the efficiency of your sealant. Over time tubeless sealant dries up inside the tyre, losing its effectiveness. The longevity of a tubeless sealant varies depending on your chosen brand, as some simply last longer than others. However, a solid rule of thumb is that tubeless sealants should stay in liquid form for around three to six months, depending on the environment, ambient temperature, and the brand's ingredients. If you follow this guide, it will most likely be due for a refresh at the same time you would want to switch from your winter tyre setup to your summer tyres. How often should you add sealant to tubeless tyres?In our second test, our workshop manager Will Poole used a Vittoria Rubino Pro Graphene 2.0 tyre in a 30mm width. For the test, 75ml of the fluid was used for the 650x47mm tyre, which makes this one of the lowest quantities recommended across the group test. Stan’s No Tubes Race tubeless sealant - Performance Before you start it’s important that you shake the bottle of sealant enough to distribute the particulate evenly and ensure there is enough of it in the solution you will put in the tyre. We are now making our Race Sealant available to riders everywhere. Stan's Race Sealant is only available by the quart.

The exact formula for a brand’s sealant is a closely guarded secret (just as with tyre rubber compounds) but effectively they can all be split into three types – those that contain latex rubber, those that utilise a synthetic alternative, and those that make do without. Most sealants also use small particles that gather around punctures, allowing the sealant to clog and seal larger punctures. What are Latex tubeless sealants? 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. 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.Switching to a tubeless road setup opens up a whole new world where flat tyres are a rarity and your ride becomes super comfy. You can stop worrying about inner tubes and run lower pressures, which makes for a cushier ride, better handling, and lower rolling resistance. Pair that with the best tubeless sealant, and you'll almost never have to deal with a flat tyre again. Sometimes, you won't even realise anything happened, you'll just keep on rolling while the sealant does its thing. How long a sealant will last depends on the conditions your bike is kept in, the sealant you've chosen, and how many punctures it'll need to plug. To be fair, the sealant did manage to plug holes up to and including 3mm at 70 psi, which is on par with both the Stans and Effetto Mariposa. The Orange Seal Regular sealant also plugged those smaller holes faster than the Stans No Tubes sealant was able to. The tubeless sealants that sealed the biggest holes, or held the most pressure with a given size of hole, were deemed to perform the best.
