I have been on steep grades where the dirt on the road caused my rear wheel to slip and that is very discomforting.

What amazes me with the pro bike riders is how they can average 30 mph up a 15% grade that is miles in length. With my own riding I have to keep my head down and not try to look for the top of the grade. Oftern there are mutiple false tops and it is discouraging to think you are at the top and come around a bend and see still more climbing ahead.
