16. I ride about 140-175 miles a week. Plus i just had my first day of work at a bike shop today and loved it. I gotta say that i absolutely hate front derailleurs on low end treks and giants. THEY SUCK. Myself and the full-time mechanic spent 45 minutes trying to get one to shift right. Otherwise it is awesome. But was i the junior you were talking about in your original post? The one whose name starts with "m"?
