I don't leave them on the bike, I only use them when inflating. I've noticed that they can and do leak, which seems to be the most common complaint, but they work well enough for my needs - I just played around with them until they got relatively tight. I keep one in the garage and the other in my saddlebag. However, I wouldn't…
