I am riding a Trek 2.3 with 50/34 and 11-25. I'm getting more comfortable at a higher cadence, (ave. 85) and feel like I am always close to cross chaining. Where I live there are a lot of smaller but sometimes steep rolling hills. When I get to a hill I have to shift into the smaller chain ring in front almost everytime, but when I get to the top I run out of gear fast and have to shift into the big ring again. Would it be better to be able to do most of my riding in the small chain ring in the front? What gearing change should I make if any?
