While we’re not sure if it’s exactly the same formula, it performs just like the original Stan’s sealant (not the Race Sealant in this list) in our tests. Most discussion about the Reserve Fillmore valves revolve around the amount of air they can flow. The brand claims 3x the amount helps seat tubeless tyres and I think that resonates with a lot of people. The thing is that with a good pump and tape that is set up correctly, you shouldn't need extra flow to seat tubeless tyres. If that's all you are trying to solve, look elsewhere. Technically, you don’t need to use tire sealant, especially as tubeless tires become even more durable. You can also patch small holes just as you would with a tubular tire. But for the cost of sealants today, it’s worth the extra time to prevent those small leaks and punctures from ending your ride for the day. First, find a suitable place to perform the task at hand. You may make a slight mess the first time around, so choose somewhere like your garage or driveway. This Conversion Kit from Milkit makes going tubeless simple process because everything you need is included in the box. A cool feature of the syringe is you can store all the accessories in the handle, even the valves. And talking of which – it’s much easier to clean off any dried-on sealant on this than a regular valve. In fact, the valves are the best thing about this kit, and I’d recommend them as an upgrade, but for some reason Milkit isn’t selling them separately.

Park Tool TSI-1 - Tubeless Sealant Injector, One Size

In the above photos, I was removing sealant from a set of ENVE SES AR 3.4 wheels with Schwalbe Pro One 28mm tires. KOM only recommends using low-ish viscosity sealants that don’t use large particles, such as Stan’s, Orange Seal, Finish Line, Caffelatex, and Slime tubeless sealant. 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. Generic, or not, most sealant injectors are like the one from Park Tools. Stans No Tubes instead makes "The Injector" which threads onto the outside of the valve core. It works just fine with the Fillmore valves and you can go ahead and wrestle with the setup and seat the tyres without sealant. Once things are good, deflate the tyre, add sealant and reinflate. With that piece of knowledge, the Fillmore valves do solve a lot of issues. One possible hazard to note is that long valve stems can potentially inhibit your ability to remove all of the sealant. The valve above is from DT Swiss, and measures about 70mm in total length. With an 80mm or longer valve, the injector straw would not reach all the way down to the bottom of the tire, meaning that you couldn’t remove as much sealant. If you ride on tubeless-compatible tires, using this sealant is as easy as pouring 2 to 4 oz on each tire, popping the tires onto the bead, and then giving them a good spin to even everything out. It promises to protect your tires from leaks and punctures that are as big as a quarter-of-an-inch.After we’d finished testing a sealant, we cleaned the tyre thoroughly with water and rags, plugged the existing holes in the tyre with tape, and tested the next sealant on a different section of tyre. Most sealants on the market today can handle a puncture of about 6mm (about 0.25”). Any larger and you might need a new tire. Most sealants use the coagulating properties of natural latex to clog punctures. Latex is a dispersion of polymers (long-chain molecules) in either water or a water-based solution of ammonia. Inside a hole in the tyre, the air pressure drops and there is a rush of air. This causes the water/ammonia solution to evaporate, leaving the latex molecules to coagulate (knit together), plugging the hole. The thing is that we didn’t realize our friends at Park Tool were enjoying our tubeless series and had decided to surprise us by sending over their new TSI-1 Tubeless Sealant Injector (thanks Park Tool crew!). And since it’s still a dead heat between road tubeless proponents and opponents that have written in, we figure at least half of you will appreciate knowing about this new tool.

To test the sealants’ operating temperatures, we put each of them in a freezer set to -18°C and an oven set at 50°C. Not exactly a real-world simulation, but it gave us an idea how the sealants would behave in warmer or colder climates. Fillmore valves are not new. I actually had my copy in hand at the end of last summer but even that was late. Ostensibly I was waiting for the right lengths for deep carbon wheels. The real reason though has a lot more to do with my understanding about how to set up tubeless tyres. In our torture chamber the Pit Stop TNT sealed the 2.75mm puncture after barely one revolution and did the same for the 5mm hole initially but it eventually when we put weight on the tyre. It didn’t seal the sidewall cut either we played around with positioning the slash rotating it to the bottom where it could submerge in sealant but it didn’t help. However, with the KOM Cycling tubeless tire sealant injector, the process is way faster and much easier. The Ultimate Tubeless Sealant lived up to this claim in testing. The use of a range of fibre lengths sealed holes consistently fast regardless of size.


When we tested a number of sealants, it was the only one to plug a hole made by an 8mm screwdriver, which it managed after three rotations of the wheel. The best part of using the KOM Cycling tubeless sealant injector is all the time and effort you save. When you use a regular applicator, the process is messy and leaks sealant onto your valve core.

Performance Cycling Limited 2023. Tredz is a trading name of Performance Cycling Limited. All Rights Reserved Designed for downhill, enduro, and road riding, the Muc-Off sealant is extremely lightweight and can last more than six months off a single application. If you use Effetto Mariposa Caffelatex, for instance, you can expect the following lifespans for each type of tire : We’ve carried out a series of controlled tests to try to find out which tubeless tyre sealant is the best at sealing holes in your tyre. That doesn't mean that the Reserve Fillmore valves aren't worth getting though. What you can expect with the upgraded valves is the end of clogs that mean the first few pumps when topping off a tyre has to break through the sealant. You can also expect to eliminate clogged valves that leak air and require swapping valve cores. Small details to be sure, but you need valves anyway and this is an opportunity to fix a few things.Double the price of the cheapest options but these are even over the top of other high quality options. Unique in the market means an extra cost in this case. In our second test, our workshop manager Will Poole used a Vittoria Rubino Pro Graphene 2.0 tyre in a 30mm width.

Next, empty the air from your tire by twisting the valve core until it won’t turn anymore. Then, using the included valve core removal tool, remove the valve core from the tire. Push the plunger all the way down to expel all the sealant from the syringe. For massive tires (like fat-bike tires), simply repeat the process until you have a sufficient amount of sealant in the tire. The Reserve Fillmore valve doesn't look all that special from the outside but the cap hides a whole new system (Image credit: Josh Ross) Design and aesthetics To really understand what's happening you'll want to think about what a valve core is. A standard valve core is almost exactly the same mechanism except it's a bit smaller and shorter. There is still a metal rod that connects through a metal sleeve. At the bottom is a flat piece big enough to cover the sleeve and there is rubber around it to help make the seal. The Fillmore valve is the same but it goes all the way through the valve core and the seal is at the bottom rather than being a removable core that sits at the top of the stem.

Average temperatures can also play into the lifespan of a sealant. If you’re not riding tubeless, your sealant is going to last you a little longer.
