When you take a traditional sized inner tube and put it in a larger tire, the rubber is forced to stretch beyond what it was originally designed for, making it thinner and more susceptible to punctures, pinches, and flats. Our Tubes are adequately sized to fit anything from 2.10" all the way to 2.40" and beyond. The next area where we thought we could really improve on is the valve. No matter how long you’ve been riding, you will have some point blown a tube at the valve through either installation or damaging it on the sharp valve hole in the rim. We decided to use our own full-length steel valve over the standard rubber valve that most innertubes use today. This steel valve is much stronger and more resilient to damage, and the threaded lockring included allows you to install and inflate the inner tube with way more ease and ensures that the valve is always fully seated and installed correctly. Oh yeah, did we add that we had a lot of fun with the packaging? I’m sure all the guitarists out there will get the name and be stoked to see these stacked up in their local shop.
