I'm looking to find a good used bike that is reliable and less than $350. It seems to me that cyclocross bikes fit the bill nicely for my purposes: able to go on pavement, smooth trails, and maybe bumpier trails. Mostly for commuting and recreation rides 20 miles or less. I'm curious, what are the pros and cons of cyclocross bikes versus full-fledged road bikes? What makes a good cyclocross and who makes good ones? Are they like hybrids? Any information at all would be helpful. Are they practical to find? Thank you for your help! I'm definitely liking this forum, great people!
