More grip and traction with Tubliss! TUbliss allows you to safely run much lower tire pressures creating a much larger contact patch, this equates to instant bolt on performance you can feel and take advantage of on the first ride. 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.
