The excitement of getting aero wheels are always sky high. You rush out to your local bike shop to get rim tape, tubes, and tires only to find out when you get home that you can’t pump up your tires. The valve is not long enough for your deep dish rims! Most bike shops will have the standard inner tubes and maybe some will have inner tubes with 60mm and maybe if you are lucky 80mm. Even that is not long enough for 50mm – 80mm rims. So that’s where SRAM Valve Extension comes into play by simply screwing onto the existing valve to allow you to pump up your tires.
