. This clever dual-gauge floor pump was exclusively designed for low-pressure Fat-Bike tyres and moderate pressure MTB tyres. A massive oversized barrel is 1.5 times larger than a standard floor pump and delivers large air volume to fill oversized tyres quickly. A 30-psi (2 bar) gauge shows precise low pressure for Fat-Bike tyres while the 75-psi (5 bar) gauge shows higher pressures for MTB tyres. An air release button on the TwinHead? allows for fine-tuning pressure.
