Some of that course is real gravel, not just HOH dirt roads. I rode most of that course in November on 27's. I am not saying I have skills or anything, but some of that shit is looooose and steep. However, it is rideable with normal gearing, dont need this crazy low gearing that these gravel nerds run.Yeah I read the description - I exaggerate - don't hate gravel, just got tired of it. At least it should be warm?
