Topeak JoeBlow Tubi 2-Stage Floor Pump – 160psi. The Topeak JoeBlow Tubi 2Stage makes installing tubeless tires quick and easy. The innovative Tubi-Head removes the Presta valve core delivering massive air flow to rapidly seat and inflate tubeless tires 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 tire. 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 tires to high pressure Road bike tires all from the same pump. Extra-long hose for added reach and durable steel barrel and large stable base makes this the perfect floor pump for all bikes.
