The way that they are marketing Chinese products now is to give you a delivery data 3 months out and then when you get the normal delivery time of 6 weeks you can't complain.

I got the plastic innertubes in and since I was putting a Goodyear 4 seasons on the back of the Ridley to add a little more flat protection, I installed one. These things are so slippery that it is difficult to get them to stay inside of the tire. So they keep sliding out a bit and you have to put the tire on over the edge of them but as soon as the tire flips over the edge the innertube pops into place without any pinching.

It inflated without and problems and although Andrew presumes that because the Vittoria TPU tubes cost $37 each they must be superior than the $4 Chinese tubes I bought, I have to tell you, I could not see how there could be any improvements. Seeing them I will now order a lot of them and at $4.00 each it seems to me to be well worth it.

TPU will outperform butyl tubes in rolling/weight though Latex are darn
close apparently! I’d with any very cheap product question it’s durability
ie how long it will last.

I found them just as easy to puncture. Slightly more slippery to mount but
fine.

As ever I suspect that you’re arguing a point not made by anyone, let alone
Andrew.

FWIW, this is another thread that is partially missing on Eternal

Huh. Same here. Now I see only Me Meriman's and yours, no

One of the reasons I gave up with Eternal September few years ago, just
flaked out too often.

Can you patch the TPU tubes or are they throwaway. I get butyl tubes
wholesale and am currently paying about $4.25 but haven't bought any in
about two years. During the pandemic many sizes went out of stock.

$4 retail is a good price for tubes, whether TPU or butyl. Kenda butyl
tubes ordered from China are about $4.25. In the U.S., the private label
"Concord" tubes at Walmart are $4.96.

I don't know (not only patching protocol; I don't know
anything about this current non-butyl tube product)

There are a gazillion different polymers with various
chemistry but the 1980s Panaracer version had its own
(optional not included) patch set:

https://cimg0.ibsrv.net/gimg/bikeforums.net-vbulletin/1600x1200/panaracer_poly_lite_tubes_ed5dd2e313a1cf56351d75e10f1a292cbc362d47.jpg

I assume the vendor offers some way to repair them but it's
unlikely to be things we typical riders have already.

Thanks for mentioning that. I ordered some self sticky patches for the TPU tubes.

The Chinese stuff or rather the very cheap stuff? No idea but certainly
Your normal brands TPU do sell patch’s though how effective these are?

I can get lifeline ie own brand stuff for £4 but to be honest now the
Gravel bike is tubeless neither the MTB or commute bike use tubes, so if I
do I tend to buy local as well bike shop is useful to me. Same with brake
pads I can get cheaper online but I generally buy from them.
