I broke a spoke on a 40 mile ride last weekend and not a week later I broke another spoke on a short 15 mile ride....A couple weeks before that also I broke one. My wheels were trued by a good bike mechanic and they've been true each time. I'm 255 and ride 12-14 avg on mostly smooth roads on a Trek 2100 with 700cx23. I got to thinking that maybe I got a cheap wheel. I went to a LBS and asked for a "cheap" wheel. Did he do just that, give me a cheap wheel? Should I buy a bettter wheel? Wider tire? Any advice is appreciated.
