This is not a set of 2 tubes (plural). I ordered this vs. the cheaper Kenda inner tube of the same model that you can also get from Amazon, as I wanted a pair and this was advertised as "tubes" indicating plural. I also confirmed this by reading the reviews which said there were 2. On receipt, I discovered that the product is 1 inner tube - NOT 2. I recommend you therefore buy the cheaper versions available on the site and give this one a miss. The seller didn't offer to resolve this, however Amazon did. Thanks Amazon.
