So I ditched 85g butyl for 35g TPU inner tubes

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Now I am curious - who here has gone TPU, what do you have to say about it, and can we get any anecdotes regarding long term reliability?
Stiff but compliant.
Aero-solid.
Agile yet stable.

That about does it.

This. I run latex tubes full time on the road, but carry a butyl spare. In the rare occasion I get a puncture, I don't want to have to take the time to mount a latex carefully on the side of the road (then when I get home, I swap back to latex). FWIW, I've never had an issue mounting a latex at the house, just talc it and take a few extra minutes to make sure it's not pinched under the bead, pretty easy. Rolling resistance beats weight savings, every day, all day. But I can def see carrying a TPU tube for a spare, and I'm thinking about doing the same, just to save space in the saddle bag.

Neither my saddle bag nor my tool bottle (the latter is what I generally use) have enough space to carry two performance butyl tubes along with the other bits. With TPU I can comfortably carry two and roadside installation is not an issue. I haven't had a flat on them yet, but just going off the initial installation at home. I think they are ideal for spares no matter what primary tube (or no-tube) is run.

So light you can pack two in place of one butyl

I can now carry two spare TPU tubes instead of one butyl which can get me home in a pinch. I also carry one TPU, one C02 and a tire lever as my race repair kit.
