> 3 dayI used Stans, prior to finding Orange Seal, and now I use Orange Seal exclusively. Ive confidently ridden Utah running Orange Seal and have also ridden—and walked—Colorado on a rental wishing I had Orange Seal (and not Stans). No puncture is the same, but Ive ridden back to the trailhead after simple punctures (you barely notice until after the ride), and even torn knobs (more noticeable, like spew-sealant-noticeable—employed a plug along with OS sealant). I even rode out a bent rim after rubbing dirt into the void with OS drying shut in the gap (see picture), though had to keep pumping intermittently because the rim was out of shape. For normal punctures, OS is quick and effective. What I like BEST about Orange Seal is the bond at the bead which is so solid, it makes re-inflation simple; I find that invaluable on the trail. I dont get that sort of confidence with Stans. TIPS: For new rubber, add a bit more than the recommendation. It forms a film over the entirety/interior of the new tire. That said, the key to tubeless sealant is actually having enough sealant IN the tire for a puncture. Shake well and add via an open tire or stem. (They make a tube injector that works great.) Shaking is also key because Orange Seal does have solids that work in conjunction with the liquid.

> 3 dayLove the product because it is eco-friendly and has saved me from quite a few flats in my tubeless tires. Unfortunately, the cap shattered in transit (probably due to the lack of cushioning). It leaked out all over the inside of the box and on a textbook book that was ordered. I’m still not sure why this was packaged together since there were other books in this same order. I specifically ordered this product because the picture online is a picture of the shop bottle, meaning that it comes in the white bottle with a safety cap. The product that came to me was the retail version. Only buy the white shop bottle if you can!

Greater than one weekThis stuff is the best. And, when it dries, it dries weightless and peels out like snakeskin. Super easy to clean up. Since it dries weightless, and hold the seals up perfectly, I top off my tires with 2oz each season and dont have to worry about anything until I need new tires. Use with DT Swiss or Mac-Off Rim Tape.

> 3 dayLets 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.

> 3 dayI ended up having Stans in my front tires on both my road bike and MTB, and Orange Seal in the rear tires. (Dont ask, long story...) Ive always read that you should never mix the 2 products. Being a skeptic, I decided to test that claim. I had a little bit of Stans left in a pint bottle, about 0.5 oz. I poured it into a small glass jar, then added 0.5 oz of Orange Seal to it. I gave it some mild agitation by shaking, basically to simulate the mixing youd get as you ride. The 50/50 mix blended perfectly - no emulsion, separation, settling - just a perfectly miscible blend of the 2 fluids. Id have no problem feeling comfortable to use that resulting 1 oz next time I top off a tire.

> 3 dayI first used Endurance in the AZ desert and it worked great for cactus punctures. It stays liquid longer than my previous brand so I’ve switched to using it exclusively.

> 3 dayYou 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.

> 3 dayOrange seal is great stuff. Bought this one as it came with injector per the description, it was not included however. Seller needs to correct listing.
