KendaThorn Resistant Schrader Tube(Return to Product Page)

I put this on my CO-OP E1.1 ebike, hopefully to reduce the amount of punctures i've been getting around Delta Park in Portland (if you know you know). It did fine on the way through Delta Park, but on the way home back from Portland Downtown, I got a flat with them.

Turns out these tubes will split on the inside of the tube, so it wasn't even a thorn or glass or rim that punctured the tube, it was the tube itself.

I wonder if its a pressure thing, since because of the weight + bike I do run them at about 50psi since I'm using a smaller than OEM tire, as we wanted to add fenders to the E1.1 bike.

This is a very heavy duty and durable tube.

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.

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!

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.

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.

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 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.

seems super heavy duty and no flats in the first 2 months

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.

Running on the kiddie's bikes, but has definitely reduced the time I spend fixing their flats.

Very well mafe and thick

Got these for my son's bike to take on the trail. So far no problems and no punctures.

Extra thick tube. With the thorns we have here in Colorado these tubes are definitely needed!

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.

Fits and works well. Is holding up to a lot of rough treatment.

Great product and great service

Recommend!!!

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.
