TUbliss Gen2 rim guard 18" (1.85-2.15)

TUbliss replaces conventional inner tubes with a small red 100 psi insert that creates two different pressure zones inside the tire itself. This enables an incredible 100 PSI of rim protection, increased tire stability and eliminates pinch flats. In turn, this allows you to run very low tire pressure for massive gains in traction and a much plusher ride.
