As a general rule, the first rider to break his or her frame is made an example of. I have heard that the now long defunct Navigators team was known for making guilty riders race the rest of the year with only one leg shaved, though they would be given a new frame to ride on. I heard through the grape-vine that last year CCB would make frame breakers wear a club cut jersey and non-bib shorts. IIRC Toyota United made their frame breakers use non insulated water bottles on hot days.
