OP here...racing huh? i tried that for two seasons with some lazy preparation, got to cat 4 by default and decided i didn't play well with others. track racing or time trials seem very interesting to me though. and to the folks that say who cares, well lots of folks i guess. im sure you care about something, we all do. maybe you like fly fishing and obsess over the perfect fly or type of rod material, not unlike gear obsession in this sport. but, if you have chosen cycling as your alpha athletic pursuit then its good to know whether or not you are doing it right.
