Nuetech Tubliss Insert 21"X 1.6-1.85

It’s about traction, lower PSI increases the control patch

It’s about speed, more traction and control means more confidence to go faster

It’s about ease, change tires faster with less hassle

It’s about the feel, get a more settled “planted” feel with lessspring effect no more ping ponging off the ruff stuff

It’s about protection, the full circumference rim lock stiffens your tires so they absorb impacts.. NOT your rims

It’s about weight, Tubliss weighs pounds less than heavy duty pinch prone tubes

It’s about fewer flats, no tube means no more pinch flats

New tires are recommended for best results
