Patrick, I don't expect to see tomato skins advertised as a cut-resistant layer and shield in bike tires because we know that short of getting out the serrated knife, the way to get into a tomato with a not-sharp edge is to puncture it easily with the knife tip ...or a goat head.Anyway, it is
On hyperbole of tires "transformed to garden hoses" - for ride quality - by using thicker TPU tubes: Worse than that, bullshit / BS, with the writer indifferent to the truth value.Or a parody of the kind that Bike Snob New York fed on..Too bad that it undercuts the serious value of that review:
Good to have an opinion of Schwalbe 14A butyls versus at least 1 brand of

which, besides, do very well amongst goatheads with OS regular forumla.

While it is true that latex inner tubes are not made in 559-inch wheel
sizes, they are absolutely made in 559mm BSD wheel sizes. Maybe not quite
as skinny as the tires Patrick Moore runs, but Vittoria makes one that is

Final update from me. Rene Herse has been very good about it and is
refunding me for the tubes that had the valve stem attachments fail.

Steve,
roger on the rotational weight for sure.. I guess where I see TPUs falling
down compared to latex tubes is a quality latex tube is around 75-80 grams,
compared to 35-45 grams for a TPU.. so not quite double, but we're also not
talking double like 100 vs 200 here.. guess I'm just not

a little O- ring on the stem. I was a bit stumped for a moment regarding

think I'll stick with latex if I want a fast rolling, lightish tube.. and

Maybe your box reads differently than mine. I will quote from the second
sentence on Step 6:
"Rapid airflow seats the tire abruptly, overstretching the tube until it
can rip"
That is the sentence I paraphrased as "don't pump it up fast, pump it up
In the site instructions it says 10psi at a time. On the box it says 20.

Good question Brian. Evidently some brands do caution that their tubes

Interestingly, Rene Herse states that TPU actually has a higher melting
