Bike tube - Choose size 12, 14, 26, 27.5, 650B, 29, 700c bike tubes - road, gravel, mountain bicycle - All tire sizes - Presta or Schrader Inner Tube - Heavy duty latex - Bike tire tube - Bicycle tube

The price is right, they hold air well and have removable valves if you need to have that feature for adding extensions or if you’re adding sealant.They seem to weigh about the same as the average rubber tube and seem to work well with the tires to provide a good feel while on the road

Tube fit great, the stem is a lot longer than expected.

The tubes I received do in fact, have removable valve cores! Very happy!

Not a lot of choices for tire tubes considering my bike's weird tire size, 26x2.35. Haven't found any stores locally that carry them, though some stores have tried to get me to take the wrong size. Watch out for that. Got a 3 pack of these. Replaced two and kept the third as a spare. Been on for a couple months now. Doing well.

Updated review as of 10/28/2019: it's unfortunate that I can't split the rating between the seller and the manufacturer of the product. The customer service from the seller has be fantastic. They obviously take pride in their operation and customer satisfaction is a top priority = 5 stars.I did receive replacement tubes with removable cores and they worked as expected; great value for sure. However, the packaging is still messed up. My first order was labeled "removable" but the actual product was fixed. The replacement order was labeled "fixed" but the actual product was removable...Original review:The tubes came in perfect condition, except that they did not have removable cores, which was the main reason I bought them. The tubes had solid seals around the valve and all the seams looked durable as well. If you don't need removable cores, these are a great option for you given the quality of the construction and the cost. These could have worked for me if the value stem was about 10mm longer to get past my Jet+ 4 wheels. As it is, I'll have to return them and try again. See pics showing advertisement of "removable core" and the fixed valve.

Inner tube ws delivered on 4-11-20, Inner tube was installed and I rode the bike many times w/o problems, last time on 6/16/20. Today 6/24 the tire was flat, did NOT hold pressure, I took the tube out of the tire and quickly found the hole where the valve stem is attached to the tube. for the photo I inserted a thin piece of grass into the hole.With the defect at the base of the valve-stem, it appears that this inner tube can not be repaired.This is a “Freedom Bike DuroLite Tube 700 x 28-32 cI’ll see if I can find a replacement tube from a different seller/manufacturer.This tube came with a 60 mm valve stem, which my rim does not need. I wonder if a 40 mm valve stem could give a small benefit.Hey, I am getting practiced in changing inner-tubes. The 2 replacement tubes are the perfect size, and they hold air pressure very well. It’ll be interesting to see how many miles(Biking time) I get on these tubes, time will tell.Konrad, in St.Louis/MO

After providing a detailed review (see below) showing the problems with the various tubes as I attempted to install the tubes, the seller reached out to me. He promptly refunded me for the entire purchase, and as courtesy, shipped me a replacement 3 pack of tubes as a good faith gesture. I have updated the review to 4 stars because of the great customer service. I had already purchased replacement tubes from another source and successfully installed those so i haven't tested the seller's replacement tubes and therefore can't speak to their quality. CP Previous review: (All three tubes had holes in them prior to ever being installed. In addition the valve stem on 1 of the 3 (i bought a set of 3) was bent and defective and was missing the retaining washer the seats against the bicycle wheel frame. Do not buy!!! Chad P)

I'm not sure what went wrong with these tubes ... but I noticed on using the first one that I got a flat after a couple days. I replaced it with the 2nd one, and it was flat overnight (not having even ridden the bike). I then replaced my rim tape, triple checked that I had no rock or thorn sticking through my tire (nope). So then I carefully tested three of these inner tubes without putting them in my tire, and two of them had puncture holes that leaked air quickly, and one leaked from one of the seams. I threw out the last (6th) one.Something is going badly wrong in the manufacture of these inner tubes!

There is a problem with the manufacture of these, a few of the 9 tubes I bought had hole on the first inflation.

My son is a crazy biker and always came home with at least one blown out tube. These seems thicker / heavier and since fitting he has had 4 outings without a flat.

Excellent!
