The Topeak Roadie DAX Bike Pump is the longest and slimmest model in Topeak’s dual-action series, engineered for road cyclists seeking fast, efficient, and reliable tire inflation. Its dual-action design delivers air on both strokes, doubling output to reach up to 120 psi (8 bar) quickly. Constructed with a durable aluminum barrel, plastic handle, and precision thumb lock, it ensures an airtight seal. The integrated dust cap protects the valve from dirt, while the included side mount bracket keeps it within easy reach on every ride.
