Defective out of the packaging
After years of buying exclusively Michelin tubes (which are increasingly scarce in local bike shops), as a convenience I decided to try this Novara/Kenda tube (23/25)as my spare. After a few weeks, got my first flat. Unwrapped the new tube from its original plastic wrap, but I was unable to inflate it at all. Fortunately, I happened to be just a few blocks from home, but imagine being stranded in the middle of nowhere without cell phone service or a ride by a defective tube? Back at home, I confirmed with my floor pump there was a huge gash/manufacturing defect on a seam line (not even around the valve stem). These tubes are made by Kenda for REI and they are garbage. Do not rely on these tubes! Never again...
A run of the mill tube
I buy these tubes for two reasons, they are the cheapest REI sells at the size I need (700x23) and the packaging makes them convenient to put in the pocket of my cycling jersey. I haven't noticed these to puncture more or less then any other tube I've used. I admittedly go through many tubes in general no matter the brand of tube or tire I am using (currently Kendra Kaliente). If I were less lazy I'd probably start patching them instead of forking over the cash but as long as these stay at $7 I'll keep buying them. My final thought on these is that they fit well on my current wheel size (700x23) and are prett easy to change out once they get a flat and put a new one on.
Half Thread Road Tubes Work Great
I keep seeing the poor reviews of the half-thread tubes and scratch my head. I've never had a problem with them. In fact they are the best of both worlds - threads to lock the stem in place at base and smooth top to allow quick release of pump head. So here's what I think is going on - the poor reviews are a result of people that don't understand that the smooth top is designed to allow the pump head to pop off easily (rather than have to twist it off and run the risk of damaging the valve). So if you don't know how to lock off the pump head you don't know what your are doing. The pro's use the smooth threadless stems for this reason. Don't buy this tube if you don't know what you are doing.
Almost completely useless tubes.
These tubes do not work with many (probably most) air pumps. The threadless section of the valve stem is too small in diameter to get a good seal, so air just escapes when you attempt to connect the pump head to the valve stem. They wouldn't seal when using my Serfas floor pump, nor two different Park Tool shop compressor pump heads that I tried. The only pump that I've gotten to seal on them is my small hand pump which I keep in my pannier for emergencies. It's amazing that these tubes made it to store shelves without being flagged by a quality assurance team, because they simply do not work, and I am far from the only one to experience this problem.
Just Okay
I used a few of these and they're nothing to get excited about. I've used them for hundreds of miles using my Conti GP4ks. I've had a number of flats with these and after switching to another brand that I get from my LBS I have gotten far fewer flats. Last time I used them I got three flats on one ride. First swap was fine, second swap I had to patch but the valve broke, so my thrid swap I had to patch again. Needless to say it was a cruddy ride and I ended up calling for a lift home. Only other issue I have had with these tubes is the presta valve. For me they seem to break too easily. When you tighten them with your thumb you have to not tighten them too much otherwise it will snap off. The stem length is good and they are only seven bucks, which is the norm for a regular tube, but just not enough for me to continue to buy these.
Would not recommend
Bought these since REI is open later than my LBS. I ran these tubes on a Bianchi Pista with Continental Gatorskins here in NYC. I commute to work M-F (8 mi a day) and casually ride on the weekend. I'm pretty cognizant of what I ride over, etc. These tubes lasted the shortest (3 weeks) compared to any other brand I've previously used. Both the front and back tubes ended up with slow leaks that were pinch flats. I check my tire pressure before every ride so that wasn't the issue. These are great if you are in a bind. But, at $7 a tube, you can find more reliable ones out there.
Get what you pay for
I've used them on both of my road bikes with 23mm and 25mm tires. I usually have them inflated between 90-120 PSI, depending on the tire and riding conditions. I'm cautious with these to avoid potholes, gravel, glass, curb hopping, etc. For a long time, they have been my "spare tube" in the saddle bag. Unfortunately they seem to fluctuate widely in quality. I've had a tube last several months, but also had to replace tubes once a week. Each time they develop a small stress puncture that slowly deflates the tube over a few minutes. After each puncture the tires and rims have been thoroughly inspected for the cause of the leak. I went as far as to replace the rims/tires on one bike, wrongly assuming they were the culprit. As far as air retention goes - I find they need reinflation at least once a week, some needing it every 1-2 days. Without being ridden, I've had a tube drop from 100 PSI to 20 PSI in 4 days. These tubes are cheap and readily available. Ultimately, they serve their purpose as emergency tubes to let me finish a ride, but not much more. I would rather pay more for the peace of mind that the tube will consistently last longer than the ride home.
OK so far
I have to say I’m disappointed with the packaging. The video showed the tube as being packaged (tightly wrapped with a thin plastic covering) so it can go into a saddle bag and take up minimal room. Instead, the tubes I received (I purchased 3) were packaged in a normal cardboard box. I put one on my bike a few weeks ago and have been having good luck so far with the tube itself, but admittedly I don’t ride as much (maybe 60-70 miles per week) as some other folks so it’s hard to tell if this tube is any better or worse than others out there.
Totally Tubular
I had one of these bad boys installed on both my road bike and Harley. This thing is the most epic of tubes. I was really surprised and quite intrigued when they were able to place oxygen, nitrogen, and nearby air in this thing. To my surprise it inflated. I'd say this is a market leader and a game changer. After changing to this tube, I know now putting air in these things is the way to go. It makes pedaling sooo much easier.
Worst tubes ever
I bought several of these, primarily for a tour on the Great Allegheny Passage Trail. The valve was bent on the first one I opened and none of them have worked with a floor pump. I have to use a hand pump to fill them, so the pressure never gets as high as it should. This is totally absurd and has never happened with any other brand of tube I've used. Clearly not all tubes are created equal. I should never have strayed from Specialized. Never had a Specialized tube fail out of the box in 10+ years of using them. Do not buy these- they are a waste of money.
