This clever dual-gauge floor pump from Topeak was exclusively designed for low pressure Fat-Bike tyres and moderate pressure MTB tyres. Featuring a massive oversized barrel that is 1.5 times larger than a standard floor pump, it delivers a large air volume to quickly fill oversized tyres. The pump includes a 30 psi (2 bar) gauge for precise low pressure readings for Fat-Bike tyres, and a 75 psi (5 bar) gauge for higher pressure readings for MTB tyres. Equipped with a TwinHead® with an air release button and an extra-long hose, it fits Presta, Schrader, and Dunlop valves. The pump's barrel is made of painted steel, and the base is made of composite material for added durability. Other features include ball/bladder heads, a hose dock, and an oversized padded handle. The pump has a size of 69 x 26 x 17 cm (27.2" x 10.2" x 6.7") and weighs 1.9 kg (4.19 lb). Each stroke delivers a volume of 722 cc, and the hose length is 118 cm.
