Hi, I'm new to mountain biking. Just bought a Small 29er Specialized Rockhopper Expert from craigslist. He told me it was 2010 model. I noticed that the top tube is curved downward. I checked the Specialized website and I cant find any frame of that shape. All the 29er rockhoppers have a straight top tube. A friend told me that it was a women's frame but i refused to believe. Does anybody know why the top tube is curved downward? The only reason I can think of is that it has 29er wheels and because of its size being small (15"), they curved the top tube to compensate for the riders height. Please enlighten me regarding the matter.
Thanks!
