I have a schwalbe 3 wheeler racing bike. I got at an auction. and I think I got scammed?
I called the local bike shop, and said, I was having trouble putting air in my tires. It has a skinny valve. I did not know I was supposed to unscrew the head of the stem. When I got to the bike shop the sales guy talked for 15 minutes trying to say his bike is better. I said, I need to go, and he showed me how to put air in the tire. he unscrewed the valve head, and took air out of a tire, and refilled it. At check out, he said, his pump will also work on regular bikes. It got me thinking, if I knew to unscrew the head of the valve, why would not my $20 Target pump work. The bike shop salesman said I need this pump. My target pump won;t work. Anyone know about schwalbe racing bikes with skinny stems, and does a regular. pump work on them.
