How big of a deal is just one small rock? I had the bike leaned in a turn yesterday and didn't see one freaking piece of gravel (maybe half or three-quarters the size of a golf ball). I assumed it would be no big deal and held my line.. It shocked me how much I could feel it and the bike got really unsettled. Obviously it's not ideal to run over things on a bike but is one piece of gravel really that problematic when you're on the sides of your tires? Should I have changed my line?
