20 miles is the longest on my FG to date since it is my go-to commuter. Hope to log many more long rides on it this summer (training). On my road bike I always carry my tool kit, a 15mm wrench/bottle opener that always stays with the FG (never know when a beer sounds good), spare tube, tire levers, CO2 kit (still looking for a nice pump as a backup), credit card, cash, phone, ID, Road ID, some Cliff Bar Shot Bloks, and a few cliff bars. I bolt on the extra bottle cage and pull off my cable lock for the long training rides, I may even use my Camelbak PowderBak for the long rides to hold extra water (if there are no stops on my route). I used it on the MS150, it was nice not needing to stop to fill up the bottles as much.
