just wondering because i was under the impression they were until i went into abike store today (didnt sell campy) and he said it is 105 level. i disagreed but may be out of my league. any impressions on the two comparison wise. no need for heavy debate, but just some thoughts as to which would be better for an occasional racer (5-10 race/year) but a heavy rider both in terms of weight (190) and miles and intensity of training. thanks everyone. -pc
