I have a ride I want to do that has a 10 mile stretch of dirt road in it. If I put 700X28c tires on my Roadie will the carbon forks be damaged from the rough road? A lot of the highways I ride on near my house are as rough or more so than some dirt roads I have ridden. How sturdy are CF forks? I have considered using my old beater but I like the gearing on my roadbike a lot better.
