I think meh. I prefer tubeless, but butyl tubes are widely available and cheap when needed. TPU tubes are super nice due to their light weight, but repair kits are hard to come-by also, while butyl tube repair kit you can find from any grocery store or gas station. Also the plastic valve stems are super spooky

I’d probably use TPU tube on like dirt jump or bmx, but anything I may have longer rides is a no-go
