The Blackburn Mammoth 2Stage Mini-Pump is a portable bicycle hand pump with two operating settings, giving cyclists a practical choice between moving air quickly and building pressure more efficiently. Its large-diameter aluminium barrel is designed to inflate high-volume mountain bike tyres, while its 120-psi maximum rating and high-pressure setting make it useful for road and hybrid cycling as well.
Switch to the High Volume stage to move more air with each stroke when a tyre is low, then select High Pressure as resistance increases. The older grey model listed under North Sports SKU BLPUMAM2S8G uses Blackburn’s TwistGrip III valve-gripping design, with serviceable internals intended to support longer-term use. An included bottle-cage-style mount gives you an accessible on-bike carrying option.
Weighing approximately 168 g, the Mammoth 2Stage is designed for puncture-kit portability without sacrificing pumping versatility. Its two-stage operation is particularly useful when switching between bikes or tyre sizes. Always inflate to the tyre manufacturer’s specified pressure rather than treating the pump’s maximum pressure as the recommended setting.
