If anyone can help me, I would greatly appreciate it. I have been riding approximately 12 miles a day on a 12 year old Diamondback hybrid. I'm ready for a rode bike, and I have a budget of $2000 - $2500. My problem is that I will have to keep this bike for a long time. I have had a few wrecks on my hybrid, and nothing major has happened to my bike. What material frame should I get? Should I be wary of carbon and aluminum frames? Will they break if you fall? How long will they last?
