Of the cyclists I know, the few who ride fixed/ss are well into the mechanical side of things, I guess almost automatically after learning how to convert/build/etc.
The majority of my friends/family who have bought a complete bike and never tinkered with it would take it to a shop, or ask one of their fixie-skidder friends.
(I think what I'm trying to say is that if you ask on here you'll mostly get DIY, and it might not be the best representation of cyclists in general)
