TPU inner tubes- any experience?

[Ming the Merciless]

No idea, not had to do that, I repair them when I get home, for touring 1 carry 2 TPU spares as they don't take up much room.

I’ve had replacement tubes puncture a few times. Plus I prefer to patch if a puncture occurs in nice weather. Patch kits being much lighter and more compact than even more tubes. Thus patching on the road would be an important consideration.

I carry some of the self adhesive patches as a get home option as well.

How easy is it to find holes in TPU out in the road?

Carrying spare tubes has been standard practice since Dunlop introduced the clincher rim in 1889.

For some, I used to always patch before 2010. But even so, spare tubes puncture, how easy are TPU for find the hole and patch?

No idea. Never fitted them.

Think only advantage of TPU tubes is lightness and ability to pack them really small so if weight and/or space a big consideration then maybe look into them. From speaking to a few mates who use them they are repairable but I'm not sure how robust they are once done. I've ridden on a repaired butyl front tube for a few years down some steep descents at speeds of 50mph+ and not worried, this on a rim braked bike. Not sure I'd have such confidence in a TPU tube repaired or not.
I carry a spare butyl tube and a pack of instant patches so if I should get multiple punctures I can get myself back on road.
