Anyone tried out Specialized Airlock Presta Valve Tubes
Frustrated to hell with messy tubeless setups. Even more frustrating locating mysterious leaks.
Did anyone give these a go, airlock presta self sealing tubes. Supposedly contains sealant.
Update:
Guess I will run with a mixed set for now. Rear wheel inflated right up after sealant swap. Got lazy trying to fix the front, threw a tube in.

If you don't figure out what is causing those mysterious leaks then you might never figure out a viable solution for you.
Leaks don't necessarily come from road debris and other hazards. If fact the last time I had a rash of flats, I found out the cause was bad habits and lack of attention to certain details in the way I was mounting the tires. So knowing exactly what caused any one particular flat can help greatly.

First I have heard of them. I wonder about this. If you do get a puncture its probably going to leak a bit before it self seals. Do you then need to top off the air pressure and of course inspect the tire for damage or foreign objects still in the tire. That is unless they seal so fast you cant even notice you have a puncture.
I might consider this tube as a spare tube.

Bell makes a similar tube with sealant in it. I used them on my mountain bike several years ago. Problem I had with those is when you need to replace the air that leaks out before the sealant plugs the hole. I literally couldn't pump air in because the valve seals. They were pretty good at getting you home if you had a puncture, but they cannot be patched either because of the sealant. Maybe these Specialized work better than the Bell's? I found them too gimmicky for me. But to each their own.

Inner tubes with sealant inside can be just as messy
(if not more so) than a tubeless setup. I have been riding tubeless on the road for 13 years and have never had a messy puncture. In fact, I flat so seldom that it has been years since I suffered a puncture out on the road. The last one was when I rode over an industrial staple with only 2 km left to the parking lot. It didn't seal, because I was actually riding without sealant, but the leak was slow enough that I made it back to my car before the tire went flat

Not these but have used Slime sealant tubes. How different are they, I wonder?
Mixed bag--heavier than standard tubes, trickier to mount (tend to twist under the tire), hard to patch if they do get a leak that does not self-seal, eventually clog the valve.
Think they work to an extent, but it's hard to really know. Puncture vine/goathead thorns are the top issue here, with glass shards and construction fasteners not far behind. Stealth potholes are their own category. Probably would not use them on a light, speedy road bike but commute and mountain bikes present a stronger case.
HTH a little
