VeloTubes Mountain Bike Inner Tubes - 4 Pack-Select Your Size (26", 27.5", 29"), Schrader Valve, Mountain Bicycle Tubes

Below is how my story with Velo tubes started. Their customer service was top notch in working with me to make me a happy customer. The hard work and effort provided by them and using a newer product that is working very well has made me change my opinion and rating. I do want to thank Velo tubes for taking their time in reaching out to an unhappy customer to make them happy!! I am more than satisfied to continue using Velo tubes in the future.First ride with one of these tubes has a nice story. After replacing my back tire with this tube from a previous flat I was able to get one 14 mile ride in on paved roads, not even off road. Got home and had it sitting in my garage a few hours later and then all of a sudden BOOM!!!!!! The back tube that was freshly new exploded. Later in the evening I went to replace it with another tube from the order, used the last bit of slime I had in stock, started stuffing it in the tire, only to see my 4 pack of 29 inch tubes was invaded with a 26 inch tube. And that incorrect size tube took up my last bit of slime. Disappointed in performance, disappointed in the incorrect materials, so that makes it pretty easy to say one of the worst items I have purchased on Amazon.

Good leisure for the cost

They seem to be a quality item. I had messed up the original tubes and needed a replacement. These tubes are a good start. I recommend them. They came quick for the rescue.

It is what it says it is!! I got what I thought I would!

These are a great value pack, haven't had.any problems. I ride on low maintained trails and these seem to hold up great.

Perfect

Just used one of the tubes and it holds air great.

have not use it yet but seems well made.
