Bombing down a nice long steep grade yesterday holding my head up to view as much of the road ahead I was tempted to rest my chin on my hands; my head was tilted up as far as my neck would allow, and if I went down any lower I reckon that a good bump would smash my hands or steerer tube into my chin and possibly injure my neck, maybe even break it- I don't know. I am wondering does that happen ? There are so many hazards, potholes, cars that could be backing out etc. that I really don't want to let my head tilt down even for a moment especially when going at a good clip. I remember watching a TT last year, the rider was like a swimmer, coming up for a breath of air- taking a peek at the road ahead, and tucking back down; but he is on a closed course I can't risk that at all.
