Making a decision to block may take a little longer than most of us would like. Small pumps although they cope well with high blood pressure just don't move much air with each movement and last time when your friend borrowed your ride, it took a full 20 minutes to return the pressure to where you need it. Fortunately Topeak designers have your eye on you creating the Pocket Shock DXG XL fork pump with a larger volume chamber for quick and efficient shock tuning. Just like his little brother The Pocket Shock DXG XL features Topeak's unique Pressure-Rite shock valve designed to be screwed on using two separate knurled sockets - the larger one is first attached to the outside of the Schrader valve to ensure safety and then the smaller head is fixed pressing the air release so you don't lose air pressure when unscrewing the pump. Large pressure gauge helps you get accurate pressure readings and the air release button makes it easy to achieve precise pressure.
