   Using these as a very compact, lightweight spare, but so far so good!
   I run my tires tubeless with sealant on everything except my townie beater and my road racing bike with skinny high pressure tires, so I thought I was pretty much done messing with tubes. Over the years I’ve tried every new tube style that has come out, including thin butyl, latex, butyl/latex hybrid, and early TPU tubes, but in my opinion, if you ride a lot, and don’t use super high pressures, tubeless is the way to go. Anyway, I’ve gotten back into these newest generation TPU tubes, because I always carry a spare for if my tubeless setup gets a really bad cut that the sealant can’t fill, and TPU tubes are a super lightweight compact option, that lets you carry a spare with less bulk, or carry 2 spares in the space of 1 conventional butyl tube. I thoroughly inspected this tube before adding it to my tool pack, and it passes my initial inspection including the all important “valve stem to tube interface” flex test (that is a common point of failure on TPU tubes) but I can’t vouch for it’s long term high milage durability. Having said that, light TPU tubes in general are equivalent to a standard butyl tube in durability, and mid-weight TPU tubes like these ones, are usually better than a standard butyl tube. I saw another reviewer complaining that TPU tubes, if punctured, require a 30min wait for glue to dry on the patch, but my understanding is that these are best patched with an “instant” style patch, which is basically a super strong piece of tape, rather than a separate glue and patch combo, so do your own research on the options if you are going to be using these as your daily drivers.

   Very thin tube!
   I recently needed a tube for my e-bike so I was looking around at different tubes and I decided to go with this particular one. Upon receiving it, I was totally shocked at how small the box was. Upon inspecting the tube, I found that it is super thin. So thin that you can see through it partially. I ride in the desert quite a bit and a thorn would go right through this tube like no problem. This tube looks like it is designed for road bikes and tires that would only be used on smooth surfaces. I decided that it would not work well for my particular application.

   Seem like a decent tube
   I ordered this tube to carry on my bike for emergency use. As such, I haven’t actually “used” it so can not speak to how it will hold up. I know some people swear by TPU tubes and use them for their daily applications due to their low weight. And the low weight, as well as the smaller packed carry size was why I chose one to carry on my bike for a spare. I have two sets of wheels for my Domane; one with 32C road tires, currently running butyl tubes, and the other set running 40C gravel tires setup tubeless. So, as this particular tube is stated to fit tires of 32C thru 47C sizes, I sounds like a great choice to carry in my saddle bag on the bike. This way, it can serve as a replacement tube when riding with the road setup, and can also work on the gravel setup in the event I get a puncture or cut that the sealant won’t seal, or that I can’t fix with a plug. It packs smaller, and is much more compact than the butyl tubes I’ve been carrying. And since it’s the size it is, it will work for the 32C, and still not be overstretched when in the 40C tires.I can’t attest that my digital scale is a “scientific calibrated” unit, but it’s always seemed pretty accurate in the past. So, weighing this tube, my scale read 44 grams. The manufacturer claims 46 grams. So, either it’s actually a little lighter than advertised, or my scale is a little off. Either way, it’s VERY close to the claimed weight if that matters to anyone.BUT, as this is a spare to carry, I have not actually used the tube. BUT, I did unroll it, inspect the tube and the presta valve. Then I put a little air in it. Not a lot as TPU tubes need the support of being installed before inflating too much or you run the risk of causing a bulge in the tube, or in my case, it could permanently stretch to be too large for proper fit in my 32C tires. I put enough air in it to make it “tight”, like a balloon, and take a full “donut” shape, but without deforming it too much. I then left it for a few hours and could feel that it seemed to be holding air with no signs of leakage. I then deflated the tube fully, and rolled it back up. Then, as is my practice with spare tubes, I VERY lightly dusted it with talc to keep the tube from sticking to itself (this can happen with butyl tubes if stored for a while, but not sure about TPU), folded a piece of painters tape over the valve to give a little abrasion protection where it touches the tube when folded, then I rolled it up in cellophane to add a little protection against abrasion in my saddle bag, wrapped it in tape, and wrote the size and date on the tape.I believe this tube will do what it’s supposed to do just fine. If and when I actually use it in a tire, and IF it doesn’t perform as expected, I’ll update this review.Hopefully someone will find this useful.

   Small and lightweight
   Shown next to the tube it’s replacing.I don’t care about the weight, but the size is impressive at a cheap price.I purchased the very expensive name brand version for my mountain bike years ago. This one is for my gravel bike and seems to be the same quality at a fraction of the price.I’ll probably inflate to test(I’ll update the review iif any surprises) and re-roll it. I normally wrap the stem a bit with soft tape to prevent abrasion and put the stem in the middle.It’s a big enough difference in size that I need to go find a smaller saddlebag.

   Confusing header
   Just one tube, not a 2pack, and levers were not included.

   heavy duty TPU inner tube
   I’m newer to actually using TPU tubes. I’ve stuck with rubber for the longest time, despite carrying a TPU tube as a spare, due to how small they pack.I’ve started to ride TPU’s but am always nervous about flats as they take a lot longer to patch & I don’t want to sit on the side of the road for 30 minutes waiting for the glue to dry.When I saw this heavy duty tube on vine, I had to get it. It’s great so far, it’s definitely thicker & heavier than my other TPU tubes, and so far I haven’t had a flat with it. I can’t tell if that’s just luck or if the heavier tube is protecting against flats, but for as much hassle as it is to repair TPU tubes out on the road (I don’t mind fixing them when I’m back home), I feel like the extra thickness of these is well worth the weight penalty. And at this price, you can’t go wrong.
