A new approach to tubeless tyre installation. The innovative tubi head removes the presta valve core before inflation which allows high air flow to rapidly seat and inflate tubeless tyres with no pressure loss or messy sealant leaks! The 2stage pump design delivers high pressure or high volume with a flip of the switch to quickly fill any size tyre. Stage 1 opens both barrels for huge air volume reaching 30 psi with 30% less effort. Stage 2 utilizes the small barrel for high pressure up to 160psi. The accurate dual scale gauge delivers precise readings from low pressure mtb and fat bike tyres to high pressure road bike tyres ndash all from the same pump. Head tubi head with extra long 360 degree pivoting hose and built in hose pressure release button.
