Back in the day "mammoth" used to mean big, but that's not the case with the Blackburn Mammoth 2 Stage Bike Pump. Although it packs a powerful inflating punch, this Mammoth is actually quite tiny. Designed for mountain bikes, the Blackburn Mammoth 2 Stage Bike Pump auto-adapts to work with both Presta and Schrader valves and a 120psi max pressure output makes it equally road worthy.
TwistGrip™ III auto-adapts to Presta and Schrader valves
Switchable high-volume and high-pressure modes for faster inflation with less effort
Rebuildable Internals
Includes cage mount
