One of the turn-offs in crit racing for me was the over-abundance of holier-than-though, prima-donna types. Many of the whom would spend the whole race sucking wheel, never taking a turn at the front, just to save everything for a finishing sprint. I only did a couple of sanctioned TTs back then (9 years ago) but it seemed to be a much more laid-back crowd. Much more of an "I'm here to race the clock and myself" mentality.
Has this been your experience?
