Kenda Thorn Resistant Tubes

We kept getting flats while ridding on our favorite trails. After installing the new tubes from Kenda, we�ve not had a flat. Great value.

Good investment

Anyone with little ones knows you don't want to have the bike unridable or spend time patching a flat tire when they want to ride. These heavy duty tubes will take a heck of a big thorn before they give up. Throw a little sealant in and they should never go flat!

Just like they say-extra tough

This tube is heavy and should help me not have to change my tire as much. Using the 20 tube on a bakfiets, so lots of weight and tricky handling.

Flat-free competition season.

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.

Still got pierced

Bought them for our Bob stroller because we kept on picking up thorns. Also bought inserts and tires with thicker tread. Did not help, still got pierced.

Tube fails at valve

Tube began leaking at valve, and separated there before removal from rim. Used with Kenda 20" tire, and this still seems OK, after ~ 1000 miles of use.

Don't need to carry a spare, levers, or a pump anymore

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.

Used on a DAHON fold-up bike, no time for punctures

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.

Bought two, one worked fine!

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.

OK

At first they looked great but one of them had a pinhole, it would go flat in two days, I had to put a patch. We'll see how long they last.

Outstanding quality, have not experience a single flat since.

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.
