Most of the tought hills that I do don't allow for this strategy. When I startedd this thread earlier in the summer I was really getting into tough climbs. My lowest gearing n my Tarmac is 30/25 - when I get to anything 8% or greater I am there and there isn't anything left. High RPM spinning is not happening either. One climb I did about a month ago started at 10% for about 1 mile and then back to 8% for a total of 10 miles. I end up in the bottom gear from the get go.
