TPU tubes for #cycling - Yay or Nay? Sources?

Anyone using TPU tubes? Would you recommend them?

I note online Chinese vendors (Temu/Ali) are about half the price of my local bike store for them. Anyone have experience with purchasing/brands for Chinese TPU tubes?

        I used Slime tubes for a couple of years until it failed. I thought I had a minor puncture that sealed because it went down a coupe of times on the commute but then stabilised

        I then did the King Alfred’s Way and it let go half way around. When I took the tyre off I saw the split and it was a mess. Sealant everywhere.

        I binned off the other one and won’t be using again. Bloody nightmare imho & enough to put me off tubeless too

            @pete @wav3ydave @voiceofunreason @adamrice @MrAndrewD @bicycling yeah. I made the mistake of getting a slime repair kit for the car (plug and gunk) but then it got recalled for containing toxic chemicals. I didn’t have the bike valve clog though, but just the though of trying to find a thorn in a tyre full of gunk is enough.

            Oh and with tubeless, remember to take out all the multiple objects that successfully sealed before putting a tube in folks!

              Since we’re veering into discussing puncture sealant for butyl tubes, I’ll share this anecdote:

              I used to work in bike shops. Someone brought in a bike with a fast-leak puncture they tried to fix with butyl sealant.

              They figured if a little sealant would help with a slow-leak, a lot of sealant would help with a fast-leak.

                They, apparently, got a huge can of sealant meant for cars and shot that into the valve.

                Likely a liter+ in total.

                The butyl tube had a 6cm tear so the tire was basically completely filled with sealant.

                It didn’t work.
