> 3 dayThis 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 dayThis stuff has been so reliable over the years. Ive tried Stans, DT Swill, Continental, even Peatys - yet I havent used anything as good as Orangeseal. Yes - the price is a little higher than other brands, but in my opinion its well worth it because it lasts longer before drying up/evaporating, and it seems to keep punctures away. At times when my friends are refilling their Stans sealant, my tires still have a good amount in them. In other words, cheaper doesnt mean better! Clean-up is easy; OrangeSeal does not turn into a mess of spiderwebs inside the tire carcass when it dries up. No stringy mess, no giant globs - just a smooth layer of sealant. Ive been using OrangeSeal for the last 3 years... and I still havent had a flat for (yup) the last 3 years of riding fire roads, trails, and even downhill. Easily a 5-star product in my book. Im only buying more because I want to top up during the hot summer were having locally.

> 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 dayBike shop, and mountain-biking family members all extoll going tubeless. So far, so good. I did four tires in short order without adapter to valve stem. Highly recommend short You Tube videos to prepare/plan. Another set of hands would have been helpful servicing 29 rims/heavy tires with liquid sloshing around, still managed without spilling a drop.

> 3 dayI had Stans NoTube Race Sealant in my tires. That was a fresh conversion to tubeless. I have no prior experience. My son did it for me. It worked well at first, but then my tires started losing a lot of pressure after about a month. I added 3 oz Orange Seal Endurance to the leakiest tire, and 1 oz to the other. I also tightened the valve stem nuts, so I cant say the Orange Seal was the ticket, but I think so. Ive been riding for a few weeks since, and my tires are only losing about half a pound each time I check, and theyre probably losing that in the process of checking them, as I have to use a Schrader adapter with my current pump. I have 650B tires, and ride about 75 miles a week, mostly on pavement. I will continue with the Orange Seal Endurance, as it was very easy to use, and seems to work like a charm.

Greater than one weekI 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.

> 3 dayIve had good luck using this product over the past few years. Ive just had normal pinholes in tires and this has sealed them very well. However the main reason that I like this product is that it lasts longer than Stans! Whenever I use stans, I have to refresh it every few months because it would dry out and turn into a little rubber ball inside my tire. I would have to break the bead and pull it out at least once a year. I dont have this issue with orange sealant. It stays liquid even a year later. My tires are also holding pressure very well between rides.
