Needed to replace the original tubes that were provided with the the bike. The OEM tubes deteriorated while being stored since this was not a bike used frequently.
I used to get one flat a week. I commute on roads and debris is a problem along the way. After installing these combined with Schwalbe Marathon Plus tires, flats are a thing of the past. I don't need to carry any tube repair gear.
These tubes are awesome. Ran the entire supermileage competition season without a single flat tire, or tube failure. In comparison, we had 3 consecutive tube failures in 24 miles of competition last year. I won't buy any other tubes than these.
if you are tired of fixing flats these tubes are for you and your kids bikes. have not had a flat yet.
I bought two, and when I opened the box, I was impressed with the ruggedness of the tube. .. I always do a soap and water test of new tubes as some come with tiny pin holes. .. One of the tubes was fine and the other has 3 tiny pin holes. Two where the valve stem is applied and one about 4 inches away. Check first! .. A defect can happin to any product. I still think they can be a good Value and great for thorn protection.
Excellent quality. I have not experienced a single flat since installing the Kenda Thorn Resistant Tube. Terrain we bike in is loaded with goat head thorns and they have not penetrated the tube since we began using it.
As I wrote in the summary, I like the tube for the price but I still had a leak from a thorn that I got from riding off road.
So far so good I ride an electric scooter and have had my share of flat tires I hope they are nail, staple and road debris resistant also.
They feel 4 times thicker than a standard tube and heavy, not a problem for me.
It's got to be an improvement on a 2x20 100psi tires
I may update in the future after some miles
I purchased two Kenda 26x2.02.125 thorn-resistant tubes.
On both of these tubes, after one ride, 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
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.
