The shorter list may be which don't. It saves close to 100gr per tire.
to be clear - its not a complete "tube" but "
an inner liner that provides an airtight chamber" that allows you to pump up a tire and hold air without sealant. Probably good for the casual cyclist who may let the sealant run dry - the tire will still work fine and hold air (if not punctured). Without this type of construction, you'll know pretty quickly when your sealant runs dry.
