Like Willy from Alexandria, I have made the GAP/C&O trip 6 times in the last six years on bikes without front suspension. Four of those trips were self-supported where the bikes were packed with tools, tent, sleeping bag, clothes, camp stove and small amounts of food. The bikes have been road bikes or modified versions thereof with wider tires and 36-hole rims. I typically use a handlebar bag on the front.
I’ve not felt the need for front suspension. However, maybe I don’t know what I am missing having not owned or used a bike with suspension.
