When riding Sat. the group I was with came along a guy pushing his bike. Two of us went over to him to see if we could help. He asked if anyone had an air cartridge. He said he had already used the one he had but he blew the tire off the rim or something. I reached into my jersey pocket and pulled out my spare. As I went to hand it to him the other person from my group said he had a pump. The guy took the pump. He worked like mad to air up his tire.

Question: Would you give the person in need the air cartridge? He only carried one on him with no other backup. Without hesitation I was going to give him my sprare...I had two on me. But after thinking about it later I thought, why should I give him a cartridge if he wasn't concerned enough about his own ride to carry a spare or a mini-pump?

I carry two cartridges AND a mini-pump. I believe in helping out other cyclists, but don't we have a responsibility to be prepared? Would you have given him the cartridge or let him pump?
