Chestnut ridge? I rode it last week. If you are used to alum, be ready for a metric fuckton more climbing. Tons of uphill switchbacks, less technical than alum, but there are still some good sections, like downhill rock garden switchbacks. Fun place.
I hiked 20 miles of mohican a few weeks ago when it wa 106 deg. out and I think I almost died. I wanna ride it though next year. I've ridden half of it in the past. I've also hiked it all in one day, several yrs ago.
