If you think about it, the usual Bicycle pump extremely uncomfortable: after all, he had no supporting devices, such as, for example, a car. However, support cyclists… carry with them. I mean a universal, or as it is called, “family” wrench. Finding that I need to swap wheels, I’m looking for a couple bricks or wood chocks, pull out tool pouch this key and threaded through one of the holes in the pump hose. Put the key on pushed the bricks and begin to swing. What does not support? A. BELYAKOV, Nurabad, Samarkand region
