The Mammoth pushes a lot of air with a low max PSI, ideal for the larger tires that come with gravel and trail riding while remaining compact and lightweight. Our Presta dedicated thread-on head sits on a pull-out hose to give more options on which position you pump from and puts less stress on the valve. Nervous about unthreading that valve when removing the pump? Enter one of the Mammoth's awesome features: the Presta Valve Tool. Simply unthread the tool from the back of the pump and tighten your valve prior to threading the hose on.
