Made from Butyl rubber to provide the best resilience to puncture yet maintain stretch.
Best size for small bikes and scooters 12.5" x 2.25" (12-1/2" x 1-1/4").
The Valve style is the common American Valve A/V also known as Schrader Valve.
This package contains two Inner Tubes so you can replace both tires on a scooter or keep one for later as a backup.
Note: When you install the tube into the rim of the wheel be sure to inflate just a bit to help prevent twisting of the tube. This will also help you reduce pinching during install.
