Can anyone else speak to the issue of a compact double, which seems to be standard on the carbon fiber bikes I mentioned? As a relatively weak cyclist that spends at least 1/4 of the year in hilly areas, I want to make sure I have low enough gears. Even the Synapse I tried with the triple was not geared low enough for me. I test rode it in Duluth, Minnesota, a city built on a steep hill. I managed to go up hill two blocks before bailing. I then rode parallel to the hill, but that street goes up as well. I could do it in first gear for the mile or two I rode. Needless to say, it flew down the hills.
I've been riding since spring and this past month put 300 miles on my bike. The prior month 220 and the month before 150, so I am increasing my mileage steadily but I still have a long ways to go to get stronger.
