The Topeak JoeBlow Mountain X Digital Pump is a high-volume floor pump designed for fast mountain bike tyre inflation with precise digital pressure control. A large 722cc stroke volume moves more air per push, reducing inflation time by up to 50% compared to standard pumps. The 3.5" LED digital gauge provides accurate readings up to 60 psi, helping you set pressure with consistency. A durable steel barrel and base ensure long-term reliability, while the RapidHead delivers efficient airflow with a secure, no-loss connection to Presta valves.Key Features and Benefits:722cc high-volume stroke: The oversized barrel moves a large volume of air with each stroke, which reduces the number of pumps needed. This shortens inflation time and allows you to reach target pressure with less effort3.5" LED digital gauge: The large digital display shows clear and precise pressure readings up to 60 psi. This allows accurate setup for different terrain and ensures consistent tyre performanceRapidHead pump head for Presta valves: The high-airflow head is optimised for quick air transfer and features an easy on-off design. This prevents air loss when removing the head, so the final pressure stays exactOversized 44.4mm steel barrel: The large-diameter steel barrel increases air capacity per stroke and improves efficiency. This supports faster inflation and reduces physical strain during useHardened steel base and construction: The robust steel base and barrel provide stability and durability under repeated use. This ensures consistent performance and a long service lifeOversized padded handle: The wide, cushioned handle improves grip and comfort during pumping. This reduces hand fatigue and allows better control when inflating high-volume tyresAccurate pressure and fast inflation are key when setting up mountain bike tyres. The large stroke volume works with the oversized barrel to move more air with less effort, while the digital gauge ensures each tyre is set to the correct pressure. The RapidHead maintains that pressure by preventing air loss during removal. Together, these features support consistent tyre setup, better grip, and improved control on varied terrain.This pump provides the speed and accuracy needed for modern high-volume tyres. Its durable construction and precise gauge make it a reliable tool for regular use. It is a practical upgrade for anyone who wants faster inflation and consistent results every time.Specification:Oversized 44.4mm steel barrel and durable steel baseOversized, padded handle provides a comfortable gripRapidHead pump head fit Presta valvesLED Digital Mid mount gauge / 60 psi (4.13 bar) max pressureCR2032 batteries x 2Volume Per Stroke: 722 ccSteel barrel and hardened steel baseHeight: 72cm Hose: 65cm
