I am a big guy (6' 8") and ride a titanium bike which has standard 700c road tires. The manufacturer (clydesdale) did orange seal when I first bought the bike... and after a year or so, they started deflating a bit too early (never on a ride, but usually within a few days) so I got this to re-seal teh tires. I picked up a syringe which made it easier but now looking back, I dont think that was absolutely essential and probably just my lack of comfort with the process - I think the kit comes with everything you'd really need. Even after a week or two the tires are still almost ocmpletely full, which is about what I'd expect even with a tube setup, so I'm happy!

I love this stuff. Everybody says that timeless yours will lose about 3 psi per day, but with this stuff my Panaracer Gravelking SS+ tires lose maybe 3 psi per week. And I’ve only ever gotten one flat and that was because I hadn’t them off in over a year but still sealed up when I aired the tire back up. I bought the big bottle this time so I could properly top them off every few months like you’re supposed to.

This stuff is 1 million times better than inner tubes. I love not having to deal with inner tubes in my bike tires. You squirt this stuff inside your tire and then you’re pretty much good to go. You may occasionally need to put more in, but it seals Holes in the tire. I’m a very big fan.

I have been using this sealant for a while now and it is very reliable. I have a Specialized mountain bike and I filled my inner tubes with this. I went about a year without a flat. I put about 750mi on my tires and I had to replace them because the tread wore down before I got a flat. If you do this setup, it's very reliable. Just make sure you buy inner tubes with a removable valve core.Once I replaced those tires, I set my wheels up tubeless with WTB tape and this sealant. I've been running it like that for a couple of months now and no leaks or flats here either.I really recommend this if you hate using mini pumps or CO2 on the side of the trail while everyone rides by!

I like the product but the packaging/injection system is a little lacking. I’ll just go with the regular bottle next time and buy a syringe.

Used this for quick repair of my MTB tire. This is easy to use and works as advertised.

I’ve used 4 or 5 different sealants, Orange Seal seems to check all the boxes, mounts up and seals well, and handles punctures before you know about them. Just remember to refresh it every 3-4 months so you don’t end up with a puncture and open your tire to find dried up sealant.

Saved my life going downhill and caught a flat, so good didn’t even know till I got back to house. Maintenance is one thing though, but average compared to other sealants.
