If you do a lot of miles, especially solo (e.g. Audax or Touring) then you need a reliable source of inflation. This mini Track pump is packed with features that make it delightful to use. Fold out T-handle, flip out foot stand, extendable and flexible valve head. And it is only slightly bigger and a few grams more than many other mini pumps with non of these features. And a genuine 100psi is easily obtained in a few minutes of pumping. Since the flexible hose allows you to press the T-handle downwards whilst the pump rests on the ground, there is non of the wobbling and wrestling associated with trying to hold a traditional mini pump onto a tube valve whilst also trying to use the pump. In short, I have been so impressed I've bought another one to go on another bike !
