This clever dual-gauge floor pump is a Topeak first and is designed to inflate low pressure Fat and Plus Bike tires.
Higher pressure pumps built to handle 100+ PSI tend not to inflate the new huge volume low pressure tires either quickly or accurately.
A massive oversized barrel is 1.5 times larger than a standard floor pump and delivers large air volume to fill oversized tires quickly.
The 30 psi gauge shows precise low pressure for Fat and Plus Bike tires while the 75 psi gauge shows higher pressures for hybrids and other mountain bike tires.
An air release button on the TwinHead allows for fine-tuning pressure.
