    He was also factoring how many he was carrying as spares into the weight saving which you haven't.

    Not sure why that matters when the Conti Supersonics are lighter, which means times 3 as you suggested, is still lighter than 3 Tubi's, or 20 Supersonics would be lighter than 20 Tubi's, point not taken

    Wow, that was pointless.
    Have you ordered them yet? No point commenting further until you have

    For the absence of any doubt this is what they look like:


    Note the model I have is the 36g, there is a lighter 24g model. For reference Supersonics are quoted at 62g. But TPU don't feel anywhere near as fragile.

    Ditto. Went through the whole year (well, April to October inclusive) and only one P.
    That was caused by what I can only describe as a metal thorn and would have done anything without sealant.

    That's awesome news, mine are still unused, aside from going out in a cycle wallet for every ride :D

    I keep meaning to order some more for other bikes, and then forgetting.....

    The expensive Pirellis on my best bike are intact, zero issues at all, and I'm still amazed how well and for long long they hold air compared to butyl, will be interested to see if these much cheaper ones are anywhere near as good.

    Interested in getting some of those. Any thoughts on how to choose the vendor on AliExpress (and good/bad experiences)? The prices (and postage) vary wildly, but it seems like they're trying to incentivize you to buy a load of them to get free postage.

    Just go back through this thread.

    You get a degree of protection with AliExpress because the buyer doesn't get paid until delivery, and I've never had a botched Ali delivery (though not the heaviest user of it).
    For what it's worth I've done three separate orders of RideNow, all from 360goonstore, and all have arrived in about a week. They must have some kind of EU warehouse because that would be amazing if direct from China.

    I have not used TPU tubes so I don't have any real-life experience with them, but according to the internet, TPU has a quick deterioration over time with a shorter life than butyl or even latex at around 2 years, but then AI said 20 years!?

    Does anyone know the facts on this?

    It does seem though, that for the price they don't seem to be worth anywhere near their asking price

    Tubulito have been around for about 5 years and I've not heard any stories of failing tubes flying around. Though admitedly quite a niche product when they were £30 a tube. I've had my own for 18 months so time is ticking and I would of course report back if any degredation failure happens....

    FWIW if you look at some of the other uses of TPU, like mobile phones, a 2 year degradation window wouldn't cut it, which suggests that the story is ****.

    Does anyone else get the impression froze must have shares in a rubber company or something? He seems obsessed with dissing TPU tubes.
    I still haven't tried them so my opinion is equally meaningless, as always

    Morning all - I'm intrigued about the recyclability of TPU, etc - I've become very conscious of my carbon footprint, can you recycle TPU (etc)? Old style rubbery jobs I would use as frame protectors, etc

    It's just a hill. Get over it.

    Cut them into sections of suitable length, tie a knot in one end and use them as rubber johnnies?

    That's what I do with my mountain bike tubes but what about road bike ?

    One which was immediately going to be consigned to the "Too good to be true" bin, but the internet came through.

    Repairing a TPU inner tube with electrical insulation tape. Yup, that's right. No fancy glues or buying patches, just good old insulation tape. Cut off the desired patch size, press down firmly and install. Lasted a 12 hour pressure test so far.

    I definitely do not have the balls to try this out but very interested in the results! Keep us posted...

    Any links to where you found this "hack"?

  • pblakeney
    pblakeney Posts: 27,486

    I decided to try Google when a standard patch didn't work. I found this tip in the comments to a video on specific TPU patches. I had nothing to lose as I was going to chuck the tube anyway. A resounding success.

    Is this on a tube that is now back within a tyre presumably?


    I know if you inflate a TPU tube to anything above very little pressure they are meant to expand beyond the point which they can return.


    On an unrelated topic of how well they hold pressure compared to any other tube, although admittedly this is the very pricey Pirelli ones (I've yet to install the RaceNow ones) I'm speaking about.

    My best bike has been sat in the front room unridden for what must be easily 6 months, possibly more due to the gravel bike.

    It's running 28s and I'd generally run them at something like 75/65 in all likelihood.

    Checked the pressure on a pump with a digital gauge, and they still had 22 & 25psi in respectively - incredible.

    IF it's linear, that's about a 2 psi drop per week!

    I have now ridden about 600 km on my RideNow tubes and I'm following this thread with interest.

    TPU is basically a plastic, so once expanded it won't return to its original size. I can't see that being an issue unless you swap it from a bigger tyre to a smaller one.

    Regarding repairing with insulation tape I expect the results to be highly dependent upon the quality of the adhesive, so if I were to try it I would use 3M insulation tape rather than some no-name tape. I have heard that self-adhesive patches designed for use on butyl tubes will work on TPU and I don't see why not, however I have used the Park patches on butyl tubes in the past and although they worked well enough initially, even sticking in attrocious conditions where I could not get the tube properly dry, they fail after a few months which would never happen with a regular rubber patch and vulcanising solution repair if done correctly. I expect any self-adhesive patch used on a TPU tube will similarly fail, you would hope that a repair done using the correct kit would be permanent. Insulation tape could be a great temporary get-you-home solution though, so long as you carry out a proper repair once you get home.

    My comments on TPU and repairs.

    The Ridenow tubes hold their pressure at least as good as butyl ones.

    The B&Q Diall insulation tape repair was done at home, is installed inside a 25mm tyre on a wheel at 105psi, and holding. It is going on my "good bike" which is not normally ridden until April unless we get spectacular weather for the time of year.

    I have used self adhesive patches on butyl tubes. They get me home but don't last long term. I do a proper vulcanised repair when I get home.

    I don't see why an insulation tape repair couldn't be done roadside but unsure if it is wet. Also, you'd want a nearly finished roll for size purposes.

    Saw on another forum that Park Tools glueless patches work well though haven't tried them myself.
