This is not exactly about fixing a bike, but here goes:
My Silica Superpista is not longer inflating tires. When you push down on the handle I can tell air is being pumped out, but if I let go the handle rises (as air is pushed back out of the tire, I am guessing). My sense is that there must be a check valve somewhere that is not doing its job. Does anyone have any advice on a fix or at least what part to order? I would hate to loose this pretty pump.
