The Topeak Roadie DAX Mini Pump is a streamlined, slick-looking pump for quickly inflating high pressure road tires when you suffer a ride-stopping flat or need to top off tires before hitting the road. It's based off the standard DA Mini Pump, but it's longer and slimmer for a sleek aesthetic and ideal fit on your road bike. Topeak's Dual-Action Technology inflates road tires twice as quickly as a traditional mini pump, so you won't have to tire out your arm, just to gain the proper pressure. It's compatible with Presta valves and comes with a handy dust cover, so the valve doesn't get caked with dirt and road debris. Additionally, it comes with a side mount bracket for easily attaching it to your frame.
