It's so funny this I saw this thread today. Over the weekend my mom was telling me that my parents went to a dinner party with their neighbors and somehow got on the topic of how I just started riding. Turns out, my dad told them all how much I paid for my bike and the brand of bike I have. Of course I was embarrassed because 1) I wasn't even there and 2) most people who aren't involved in cycling may think it's too much to spend on a bike (my parents are in this category). Luckily, one of their neighbors is a cyclist and has heard of my bike so he knew what a great deal we got on it

I'm with the majority of the people above...I'm uncomfortable telling the price unless they are truly interested in buying one for themselves. I felt weird telling my parents but I did and then look what happened!
