This clever dual-gauge floor pump was exclusively designed for low pressure Fat-Bike tires and moderate pressure MTB tires. A massive oversized barrel is 1.5 times larger than a standard floor pump and delivers large air volume to fill oversized tires quickly. A 30 psi (2 bar) gauge shows precise low pressure for Fat-Bike tires while the 75 psi (5 bar) gauge shows higher pressures for MTB tires. An air release button on the TwinHead┬« allows for fine-tuning pressure.HEAD: TwinHead┬« w/ air release button & x-long hose Fits Presta / Schrader / Dunlop valvesBARREL: Painted steelGAUGE: 30 psi / 2 bar, 75 psi / 5 bar Base mount analogHANDLE Oversize paddedBASE CompositeADDED FEATURESBall / bladder heads, Hose dockSIZE 69 x 26 x 17 cm / 27.2ÔÇØ x 10.2ÔÇØ x 6.7ÔÇØWEIGHT 1.9 kg / 4.19 lbVOLUME PER STROKE 722 ccHOSE LENGTH 118 cm
