Pump chamber of a Bicycle wheel, for example after repair or tire, the operation is quite tedious because of the low performance of the supplied pump. Besides, there are pumps, hose attach at the end — then the job is also heavy. Because the pump has to keep on weight, creating pressure with one hand and the other opposing him, that is producing double the work. Motorists are also experiencing similar difficulties, moreover, often fail check valves. Another “disease” pump — jump off of the hose from the neck of the connecting fitting when you create a significant pressure — eventually becomes chronic.
Therefore, motorists at the first opportunity try to replace the stock manual pumps for more convenient foot or even compressors.
Cyclists also work on the pumping of the tires of the wheels can if not easier, then at least to accelerate and make it less burdensome with the help of motor pump, even with the above faults.
The only thing that will have to be redone for it is fitting. The fitting must be cut off the neck, which was worn (and often off) the hose until the hex part (under the wrench “12”). Then drilled through hole to a diameter of 6 mm and cut it in the thread under M6 hose fitting Bicycle pump.
Modified fitting automotive pump.
If the car is not running pump check valve — not a problem. His task will be successfully a rubber ring valve Cycling valve. Now using a more efficient car pump, you can significantly speed up tire inflation (cameras) bike.
