Bummer: realizing your shiny new bike needs a derailuer adjustment on mile 7 of your 14 mile ride.

Coolies: Realizing, while making said adjustment the next morning, that instead of a mediocre set of cranks as specified on the manufacturer's website, your bike has the best alloy cranks Truvativ has to offer. And you didn't pay extra!

What? You think I'm going to get a bike that cool and not talk about it? Yeah, ok, category coming soon.
