presta pump With their upright designs and large barrels, track models can deliver more air to presya tire with each pump known as volume-per-stroke.
Combined with the downward force of gravity, their broad, t-shaped handles provide a great deal of leverage to reduce effort.
Bike Tire Presta pump. Base designs vary; some extend in only two directions, such as the Blackburn model pictured below, while others feature three evenly-spaced feet for maximum stability.
