Taking 2 Dahon D7 Mariners to S. Vietnam and Cambodia probably 1500 miles. One is new and the other is years old with all original major equipment except tires, tubes, brake pads. Want to carry some repair supplies and would like some feedback on what to bring that you might not be able to get there. So far tires, tubes, patch kit, universal tool, spoke wrench, spokes, brake pads, cables for gears and brakes, pump. What else would be wise to bring, spare derailleur, hanger, gear shifter.
