for me as far as I'm concerned the hardcore XC guys around here are also hardcore roadies and what i've figured out is that they are big D-BAGS, my buddy is an XC runner converted to biking because of his knees, so he buys a road bike and rides more than anyone I know, he rides with no shirt and jean shorts or baggy cargo shorts and is a good rider, but gets crap from the spandex wearing, weight weenie types, also a couple times riding the same trails the weight weenie XCers ride on my bike they give me looks and mutter **** towards me and I then just smoke em downhil
