Stan's No Tube Preventive Liquid Tyre Sealant

Product Information

Further down, we also answer some of the most frequently asked questions about mountain bike and gravel tyre sealants. There's more advice on tubeless tyre set-up from an expert in our piece on tubeless tyres: are you doing it properly? What to take with you if you're riding tubeless 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.

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. 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. They also help form an airtight seal between the wheel rim and tyre when you first mount a new tyre, so that the tyre will hold air and keep its pressure.In the first test, we used two Michelin Wild Grip’R 2 tyres, and tested three sealants with each tyre. 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.

Another sealant stalwart, Orange Seal is a brand with a long history. However, in this test, the results weren't superlative. Muc-Off 's pink logo is nearly synonymous with bicycle cleaning and lubes. Many of its products have adopted the pink colourway, and this sealant is one of them. The pink colour is not just for being cool, though, but it highlights any wounds in your tyre and uniquely shows smaller sealant bungs that might have formed unnoticed under a UV light. 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. It's a good idea to carry a pump or CO2 canister so that you can get some more pressure into your tyres. Sometimes the sealant plug just won't hold at higher pressures, so you might need to ride a soft tyre home. Leave it overnight and it will often have set enough to take full pressure though. 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).In our second test, our workshop manager Will Poole used a Vittoria Rubino Pro Graphene 2.0 tyre in a 30mm width.
