Never implied Mayo's rig was low end. My comment was with regards to the fact that the majority of riders probably would never ever push a "high end" ride to the edge of thier performance envelope.
The advent of reasonably priced singles and fixes from manufacturers provides ease of entry into the sport. You know everything works. Some research prior to buying might reveal weaknesses, or what you might expect to upgrade (Fuji's chainring seems to be kinda lame, for example).
And not everyone has easy access to frames, sources, etc. I bet in my county, I've spoken to both of the other two fixed gear riders.
