I currently have a Specialized Sequioa triple (50, 39, 30). I am looking to upgrade later this spring (Roubaix). I either ride 1 hour after work or 5 hour ride on weekends. All during good weather. Thus what gear ratio or combination will represent a compact double's 34/27? I would like to make sure I still can make it up the hills in my area before pulling the trigger on a compact double otherwise I need to stay with a triple.
