The fatigue strength of aluminum comes in to play over time verses surface wear. Maintaining good spoke tension and tire inflation helps. A full suspension frame may help reduce impacts at higher speeds. The suspension stem and seat post on my 2000 Jamis Aragon along with sealed bearings has contributed to long and trouble free commuting at 10-12 mph. You may be running at up to 30 mph with more weight. Look for components suited for serious downhill riding.
