This Topeak mini pump is a great choice for MTB riders. Its larger barrel pumps more air volume, getting you back on the trail faster. The 1-1/8” easy - to - read analog gauge ensures perfect inflation every time. With Dual - Action (DA) technology, it doubles the air volume per stroke and quickly inflates tires to the right pressure. The integrated dust cap keeps the pump head clean, and the thumb lock lever guarantees an air - tight seal. It was named the 2020 Bicycling Magazine Editor's Choice for the best high - volume mini pump. Key features include Dual - Action technology for 2X faster inflation, a large integrated analog gauge, and a side mount bracket. The pump head fits Presta, Schrader, and Dunlop valves. It has an aluminum barrel, a polymer thumb lock/handle, a capacity of 60 psi / 4 bar, and a volume per stroke of 82 cc (pull + push). It measures 25.3 x 4.6 x 3.4 cm / 10” x 1.8” x 1.3” and weighs 152 g / 5.36 oz.
Using this Topeak mini pump is easy. First, choose the right valve adapter from Presta, Schrader, or Dunlop options and attach the pump head to your bike tire valve. Make sure the thumb lock lever is tightly closed to create an air - tight seal. Then, start pumping. With the Dual - Action technology, you'll notice that it inflates the tire faster as it delivers air on both the push and pull strokes. Keep an eye on the large analog gauge to reach the desired pressure (up to 60 psi / 4 bar). When you're done, remove the pump head gently. As for maintenance, keep the integrated dust cap on when not in use to keep the pump head clean. Wipe the pump with a dry cloth after each use. Store it in a cool, dry place. If the pump seems to lose efficiency, check the seals and connections. And don't forget, the side mount bracket makes it convenient to carry the pump on your bike.
