    You will not find a better tire sealant. Orange Seal endurance lives up to its name. I live in Colorado and Goat Heads and massive constant construction mean flat tires every week unless you use Orange Seal Endurance in your tubeless tires.

    This is a really good sealant. In several thousand miles using this sealant, I have not been stranded roadside fiddling w tubes. It seals much better and holds longer than Stans. If you use Orange Seal (or other) threaded stems, you can add sealant without even unmounting the tire. A reliable tubeless tire setup with Orange Seal is the safest way to ride. No blowouts or pinch flats that might cause a crash or getting stuck hazardous places messing w tires when conditions are unfavorable. Orange Seal will keep you riding rather than messing with tires. I didnt comment about use, because its incredibly simple to pour or inject then inflate (often with only a track pump needed. Put a few OZs in, pump, spin, ride. Refresh every few months.

    Lets be honest here, the average cyclist is often lured into believing claimed benefits of a product without ever witnessing any valid tests to back the claims up. Youll hear all kinds of anecdotal claims of how great tubeless tires are, but you rarely hear about the many drawbacks - and the fact that you probably are a lot better off just sticking with good old tire tubes. Most common tubeless benefits cited (parroted): * Run at low pressures without going flat This is primarily something that people who ride off-road claim as a benefit, that by going tubeless you can drop the tire pressure lower than you could with a tube to get more grip on loose/uneven surfaces...whereas if you were using tubes youd be dealing with pinch flats once dropping below a certain threshold. False - properly installed tubes will not pinch flat even at lower pressures, and tubeless tires suffer from burping where the bead breaks momentarily allowing a lot of air to escape. The benefits of super low PSI are also dubious at best. * Never any flats This has nothing to do with tubeless and everything to do with the liquid sealant that you have to use as a stopgap to make tubeless work in the first place. Because spoked wheels are inherently not air-tight, for tubeless to work, a seal must be created. This is done by taping over the spoke holes and using the sealant to form a bead between the tire and rim. You chould just as easily add this sealant to a tubed tire if avoiding flats is your main concern. * Faster ride / better handling Totally subjective claims that really dont have any basis in reality. A good rider will do just as well with tubed tires as he would would tubeless. In many cases the sealant ends up being heavier than a decent tube, plus having liquid in your tires does not lend itself to better performance or handling. Orange Seal ----------------------------- So what is the problem with this orange stuff? First of all, it is poorly packaged. The bottle arrived partially empty because it leaked out. The seller puts them in zip-lock bags to prevent the leaky bottles from making a mess in transit, but youre still out a couple oz when it arrives. Next, this stuff is very watery and does not aid in forming a bead with tires that are not at least tubless ready. I have inferno 27 rims and tires that are tubless ready, but this stuff could not seal the minor gaps. As soon as the air hose was disconnected the tire would deflate. Third, see above, tubeless is largely a meme bandwagon that offers little or no benefits and only adds cost. - Tubes are cheap and can last for years. - Tubes hold air better and will not need to be inflated every single time you go for a ride. - Tubes, when properly installed, will not pinch flat. - Tubes can also be filled with a small amount of sealant to provide anti-flat protection, if that is a concern for you. - Tubes do not suffer from burping. - Tubes do not require an air compressor or charge pump to install. - Even if you go tubeless, if something causes your tire to go flat, you will need a tube to ride home. The cycling industry preys upon fools by trying to make bicycling depend upon expensive consumables that need frequent maintenance. Just stop.

    Works great. Just installed my first tubeless tires. No leaks and they hold air. EDIT: A couple of months down the road, had my first experience with a cut in a tubeless tire. On an urban ride with my gravel bike and felt the tire getting spongy. Started to get worried when I added air but the tire continued to leak (could hear the leak). But, in about a minute or less, the sealant sealed the leak and I was able to continue the ride. I have since ridden a very rough 55 mile gravel ride and the tire is still holding air. Great stuff. 2nd Edit: That tire with the cut... I was able to ride it until the tire wore out. The sealed area was never an issue through several thousand additional miles. Talk about being confident. Note: I just add a bit every couple of months rather than clean and refill since I will wear a rear tire out in one season.

    Using it on four mountain bikes and one gravel bike last about 4-6 months at a time.

    I own a small bike shop in the Adirondacks. Everyone up here runs tubeless, even the roadies. So over the past 10 years I have tried all the sealants. Ive tried making my own, used motorcycle sealant, etc. The best, by far, is Orange. It is EASY TO CLEAN UP and remove from tire treads and sidewalls, seals great and lasts quite long. Its expensive, but its really worth it to us. Id rather set up a wheelset with Orange once, then have to take the wheelset back in and redo the sealant because it didnt seal properly. That costs me money. So in the end the higher price point is actually saving me cash. The endurance I find is good for MTB tires and fat bikes, but the race version works best for road and gravel tires. The endurance is too thick for the smaller tires.

    Use this in my MTB, gravel, and road bikes. Was out for a road ride recently and suffered a puncture that I never knew about until I got home and saw some sealant had sprayed onto bike while it was sealing up. Same tire a couple days later, hit a junk of metal in the road. Spewed sealant for a bit as it did its magic but only lost 10-15 psi and was able to continue my ride. Outstanding product from a great brand. Highly recommend.

    I like the texture of this stuff, as it creates a kind of latex layer around the inside. That can help the sealant do its thing. On the down side, I live in a hot and humid climate. I find that I need to check on the condition of the sealant every three weeks. It can separate and dry up in a summer month.

    Swapped my tube setup to tubeless recently. With the help of orange seal, all the minor leaks and things were easily resolved! Took about 72 hours to completely seal without the need to continue adding air.

    I’ve always used Stan’s because it came with my bike and I’ve never put much thought into it. Switching from Stan’s to this I can actually feel a difference in the way my bike rides and the seal seems more durable. Been using orange seal for 6 months now and I won’t go back
