We test seven of the best track pumps
When connected to a flat tyre it took a few strokes to get a good seal behind the head before the hissing ceased.
Once going - or if topping up tyres - the pump works well enough and the valve release mechanism is good.
A thin plastic base did flex more than we feel is ideal and over time we have experienced leakages from pumps with similar stiff oversized aluminium barrels being fixed into plastic bases as seen here.
The 28-stroke inflation requirement was ballpark but not fantastic.
