I have an Airworx Control Track pump and for all the time I've owned and used it, I've had problems removing the pump attachment from the presta valves.
I remove the cap, unscrew the valve and tap it to free it up, letting a small amount of pressure out as I do so. I attach the end of the pump hose, lift the lever clamp and then pump to the required pressure. It's removing the attachment after this that is the problem. It is incredibly difficult to pull off. I release the lever, do my best to hold the base of the valve with the little round nut with my left hand and pull the attachment from the valve with my right. After several weeks, the valve just tears off the inner tube because I cannot hold the base of the valve down and it requires an enormous effort to get it off. It proved impossible to remove this morning and despite checking the lever was released and doing my best to hold the base to the rim, it tore off again.
I cannot find anyone having similar issues on this forum. Is it possible I have a faulty attachment (oo er). Or is my removal technique suspect (oo er).
Any advice would be most welcome!
