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?#bicycle #bicycling #BikeTooter @bicycling

@wav3ydave @pete @adamrice @MrAndrewD @bicycling I scrolled through all the replies and didn't see it mentioned yet, but I may have missed it:Rene Herse now sells TPU specific sealant: renehersecycles.com/shop/equip

@pete @wav3ydave @voiceofunreason @adamrice @MrAndrewD @bicyclingI 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 stabilisedI 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!

@Pionir @pete @wav3ydave @adamrice @MrAndrewD @bicycling 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.

@Pionir @pete @wav3ydave @adamrice @MrAndrewD @bicycling 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.
