Because people are dumb and consider riding a Trek to be some sort of conformity; by badmouthing Trek they think they are unique in their non-conformity, not realizing that they are conforming with the non-conformists.

You don't like Trek? Cool. There are people that do, though -- does that make them any less of a rider than those who don't like Trek? Nah. I don't like Schwinn... wouldn't ride one. Does that make me a better rider than one who rides a Schwinn? Nah. It's all personal taste.

Besides... what's it all about? Is it all about getting out there and riding your bike regardless of brand, or is it about nutting up on someone because they ride a brand you don't like?

I tell you what -- I ride a Trek 1000 that I've upgraded to a consistent 9-speed Tiagra group throughout. That's a double whammy right there -- an upgraded Trek 1000, and with Tiagra, not 105 or Ultegra. Go ahead, talk smack... I'll just laugh at you as I ride away. Because that's what I do with my bike -- ride it.
