KendaThorn Resistant MTB Tube(Return to Product Page)

I use these on my hardtail 26 MTB in the Rio Grande Valley (New Mexico), land of the goathead, aka puncture-vine. A regular tube might last ten miles between flats, and it always happens at a bad time and a bad place. So I got these Kenda TR tubes and put 'em in. Hey, no more flats!! Seriously, these things have gone about 600 miles with no punctures. The tires get stuck with goatheads, but never penetrate the tube. I periodically dismount the tires and pluck out the thorns with needle-nose pliers.

Only disadvantages are they're heavy, if you prefer light wheels, and they're kind of hard to mount, stuffing all that rubber in.

Like Chris from Phoenix, I too experienced separation of the valve from the tube. Mine were purchased for a large garden cart in September of 2015. After a couple of months, with very little use, one tube went bad. A year later, the other is still holding.

Using these on mountain bike with street tires and have had no flats. Normally get lots of flats from goat head thorns but with the thicker outer tube the thorns do not penetrate the tube.

Would highly recommend these tubes.

As soon as I inflated this tube it started leaking from a pinhole defect near the valve stem. I had read about others having this problem before purchasing but decided to take my chances. Clearly there is a systemic quality problem with these tubes. Not recommended until the manufacturer proves they have remedied this problem.

These tubes still not strong enough to resist thorns in az.

Still looking for a solution to thorns and road debris in AZ

After experiencing 3 flat tires in two weeks due to nasty thorns on my new daily bike route, I replaced my ordinary tubes with these Kendall thorn resistant tubes. Staying on my same route, I haven't had any more flats in the six weeks since! Yay! They were really no more difficult for me to install than the light-weight tubes.

I have not had a flat tire yet ever since I bought this tube...I still need to know if this tube can withstand that evil GOAT'S HEAD thorn...if you folks are familiar with this thorn from a grass looking weed...We were out camping for 3 days and we have a total of 8 flats...that was a very disappointing experience.

Very easy installation with no problems noted, holds pressure well (running 80 psi nitrogen). Good value for casual around town rides.

I purchased these tubes with good tires, a great combo, I rebuilt my old mountain bike, a tried and trusted early Giant Attraction this made it a warrior bike....bar none!!!!

We used to have a chronic problem with flat tires until we started using these tubes and tire liners. No more flats!

Aside from thorn resistant, these inner tubes are great for high heat resistance as well, not as likely to pop in a storage shed or shipping. I wouldn't use a regular tube in any bicycle I've ever owned, I've always used thorn resistant tubes and always have high success with them.

Rugged tube, no slippage on the rim & stay in place. Thinner tubes tend to move around & bend the fill valve sometimes causing flats.

I purchased two Kenda 26x2.02.125 thorn-resistant tubes for a

mountain bike which is used mostly on the street but subject to the

goat-head thorns which quickly puncture most tirestubes. I prefer

thorn-resistant tires since they are thicker and usually last several

years without punctures. I have used other brands of tubes

(e.g. Avenir and Bontrager) but this was my first time using Kenda.

Unfortunately, On both of these Kenda tubes, the valve separated from

the main tube so they leak air very quickly. It seems that the factory

ran the blue alignment line under the place where the schrader valve

bonds to the tube, which may have contributed to a poor bond and

failure. (You can see the blue line running under the valve in

the BikeTiresDirect photo of these tubes).

The tubes are made in Taiwan and in other ways, these tubes seem to be good quality.

but I will not purchase this brand of tube any more due this defect.

I think Kenda needs to solve this manufacturing problem.

Also, other reviews of these tubes e.g. on Amazon indicate that other

people have seen this tube fail in this way. I wish I had read those

reviews before ordering them.

Otherwise, if the tube did not have this defect, I would have rated them

as an excellent value.

I was thinking about trying to get some wet-suit cement to fix them

but I don't think I will bother.

I have not had any flats since switching to these puncture-resistant tubes. I highly recommend this product to anyone experiencing frequent flats. Kenda also offers a puncture-resistant tire. The combo virtually eliminates flat tire inconveniences.

What a great buy! I havent had a flat since putting this tube on my emountain bike!
