Not trying to come across like a jerk here, but just to save you some embarrassment in a face to face conversation with someone else. I wouldn't call your bike "custom". A Custom bike means the frame has been custom fit to you by geometry or has some sort of aftermarket paint. What you have is a mass produced frame, with components that half the world uses, which makes it a production bike with different wheels. You may have personalized it with purchasing items such as wheels I guess, but neither the frame or components are considered custom or even one of a kind. Even if your wheels are hand built, that does not make your bike custom. It means your bike has "upgrades".

My bike doesn't have one stock bolt or part that it came with. My bike is fairly one of a kind and different from most other cannondale supersixes, but is still considered a production bike, not custom.

Custom = a bike built with specific measurements which contains special geometry or custom paint.
Production = Any bike that is mass produced and come with stock sizing and paint scheme.
