Enabling my wife's bike to use presta valves is actually a good idea. I can just keep one kind of tube in stock.At the risk of showing my foolishness one more time . . . you could also get those little rubber spacers that allow your wife's bike to use presta valves.
It kind of depends on your druthers, but schrader valves have always been awkward for me with most pumps . . . fine at the gas station or if you have a compressor, admittedly.
Of course, you will probably wait to use up the spares you have . . . could be another decade.
I am going to be quiet now and learn from your experiences.![]()
The learnin's going both ways.
