• TPU Innertubes

    From Tom Kunich@21:1/5 to All on Sat Sep 30 11:10:23 2023
    While Vittoria has been advertising these things for a preposterous price of $37 apiece they are the lightest available. Though I'm not sure that makes much of a difference. The Chinese versions are about the same weight as a Latex tube but they don't
    have to be pumped up for every ride and they are more flat proof than rubber tubes. They are probably a little harder to install because they are sized for 32 mm tires but I ordered some to test. If they don't need pumping up all the time I will consider
    them a success.

    Going back over the advertisements it appears that the Vittoria and Ride About (Chinese) tubes weigh the same. If they are the same quality you CAN get the Chinese TPU tubes for $2 apiece vs. the Vittoria $37

    They will probably take a little experimentation since they don't stretch much and might pinch flat while you're trying to mount them. I'll let you know. I wouldn't believe that the difference in rolling resistance would be measured.

    Make sure they are correct size as they don’t stretch as much as your normal tubes. Or they will pop!

    I used them, noticeable more comfortable or supple puncture just as easily speed? As with tubeless probably measurable but can’t say I’ve noticed or
    tested for that matter.

    As far as I’m aware in terms of speed TPU/Latex/Tubeless are all in same ball park.

    28 mm tires and 32 mm tubes. They are advertised as being harder to flat, but I don't know how you would measure that.

    28 mm tires and 32 mm tubes. They are advertised as being harder to flat,
    but I don't know how you would measure that.

    Not in my experience! If I had a pure road bike and didn’t want the faff of tubeless then I’d certainly consider though expensive tubes, I use them as spares as so small.

    With the road bike used to average 2 a year with gritty lanes and gravel
    paths so potentially your dryer environment would be better still.

    Can get fixes to seal the tubes but how well they work? So a puncture can
    be expensive!

    From China you can get them cheaper than any other tube here.

    When they shut down Vittoria in Italy they announced that all of their tires were going to be made in China. I don't know why they would have announced China and then build their tires in Thailand since labor is cheaper in China.

    Of course that would suggest why the TPU tubes from Vittoria are $37 and those from China are as low as $2.

    28 mm tires and 32 mm tubes. They are advertised as being harder to flat,
    but I don't know how you would measure that.

    Not in my experience! If I had a pure road bike and didn’t want the faff of
    tubeless then I’d certainly consider though expensive tubes, I use them as
    spares as so small.

    Roger Merriman

    From China you can get them cheaper than any other tube here.

    You can I’ve not used them myself the Chinese cheap ones that is!

    Roger Merriman

    ALL of Vittoria's products are made in China so the difference in their $37 innertubes and my $4 one's are the color.
    That is absolutely not true.
    Vittoria's parent company is Swiss and the majority of
    product is Thai.

    When they shut down Vittoria in Italy they announced that all of their tires were going to be made in China. I don't know why they would have announced China and then build their tires in Thailand since labor is cheaper in China.

    Of course that would suggest why the TPU tubes from Vittoria are $37 and those from China are as low as $2.

    I have no idea but Vittoria Thailand has been a main
    supplier to us for 25 years.

    One possible explanation may be that Vittoria inner tubes
    are not crap.

    You seem to be implying that the Chinese versions are crap. That "test" that Mariman cited wasn't any sort of a test. Because TPU doesn't expand like latex or rubber, they have to be held inside of a tire. So you can't judge their worth from that.

    much and might pinch flat while you're trying to
    mount them. I'll let you
    know. I wouldn't believe that the difference in

    Make sure they are correct size as they don’t
    stretch as much as your
    normal tubes. Or they will pop!

    I used them, noticeable more comfortable or

    28 mm tires and 32 mm tubes. They are advertised
    as being harder to flat,
    but I don't know how you would measure that.

    Not in my experience! If I had a pure road bike and
    didn’t want the faff of
    tubeless then I’d certainly consider though
    expensive tubes, I use them as
    spares as so small.

    With the road bike used to average 2 a year with
    gritty lanes and gravel
    paths so potentially your dryer environment would
    be better still.

    Can get fixes to seal the tubes but how well they
    work? So a puncture can
    be expensive!

    Roger Merriman

     From China you can get them cheaper than any other
    tube here.

    You can I’ve not used them myself the Chinese cheap
    ones that is!

    Roger Merriman

    ALL of Vittoria's products are made in China so the
    difference in their $37 innertubes and my $4 one's are
    the color.
    That is absolutely not true.
    Vittoria's parent company is Swiss and the majority of
    product is Thai.

    When they shut down Vittoria in Italy they announced
    that all of their tires were going to be made in China.
    I don't know why they would have announced China and
    then build their tires in Thailand since labor is
    cheaper in China.

    Of course that would suggest why the TPU tubes from
    Vittoria are $37 and those from China are as low as $2.
    I have no idea but Vittoria Thailand has been a main
    supplier to us for 25 years.

    One possible explanation may be that Vittoria inner tubes
    are not crap.

    You seem to be implying that the Chinese versions are
    crap. That "test" that Mariman cited wasn't any sort of a
    test. Because TPU doesn't expand like latex or rubber,
    they have to be held inside of a tire. So you can't judge
    their worth from that.

    I don't judge their worth at all. I hope never to have to
    (thinking here of Poly tubes from the 1980s).

    My general experience makes me suspect that 'same product'
    at 1/20 the cost is not the same product. YMMV


    p.s. Blast from the past: https://cimg0.ibsrv.net/gimg/bikeforums.net-vbulletin/1600x1200/panaracer_poly_lite_tubes_ed5dd2e313a1cf56351d75e10f1a292cbc362d47.jpg

    Japan did much the same thing after WW II. Cheap stuff built to no
    standard what so ever. Sell cheap as there is a large market for
    "cheap stuff" and as profits increase it is easy to increase quality
    and gradually move up market.

    I suggest that being close to raw materials is fine but perhaps the
    US$9.18 a day (legal minimum) is an incentive (:-) The other major
    rubber growers in the region, Malaysia and Indonesian,have higher
    minimum salaries.

    What happened to the COST of these TPU innertubes? I ordered three of these last month for $4.00 apiece and then found another source for $2 each. I should have immediately ordered a year's worth because they are now selling for as much as the Vittoria $
    37 tubes.

    On the average now they are going for $7 each and as far as I can make out this is entirely due to the YouTube videos showing tests of them. These things are very easy and cheap to build since all you need is to cut the material and thermally bond the
    edges of the material. I like them for one reason - there are no pores in it like there are in latex or rubber tubes so they don't leak air and don't have to be pumped up all of the time. However, Latex STILL has lower rolling resistance in the tests (
    lower than tubeless).

    This is exactly the same tube from the same manufacturer that I bought mine from for $4 per tube.
