After seeing this question, I realized we've had a few questions about fitting and finding bikes for women. Have created a womens-bikes tag.
Before we start applying this to older questions, can anyone think of a better tag name, or are we good with this one?
I'd personally prefer something that doesn't imply that women's bikes are the exception to the rule. And "women-specific-design", as has been pointed out, is a term for Trek bikes.
Edit:
Based on comments below, I've retagged the three questions previously tagged as womens-bikes to women-specific. Please, everybody feel free to retag other questions as appropriate. That would include bikes, clothing, and other issues. Have linked to this page from the tag wiki.
