Nuetech TUbliss for rear wheel with 18"

The TUbliss System works by replacing your conventional inner tube with a smaller, higher pressure insert that hugs the inside of your rim. This creates two separate pressure areas inside your tire. One area inside the high pressure insert. And another lower-pressure area that fills the rest of your tire where your old tube used to be. Inflate the high-pressure insert and it locks the bead in place to form an airtight seal that also protects the rim from impact.
