Hi everyone,
Me and my eternal bike looking and shopping.

Just wondering what is really in a frame and what makes some frames more expensive than others. Of course there is frame material, but we'll take that out of the equation.

It seems that there are some frames out there that go for a premium price while other seem quite cheap. It seems to be roughly organised into three categories
1 - Boutique brands, are the frames actually better?
2 - Standard brands, run of the mill kind of thing. Trek I suppose.
3 - Brands not well known for making quality bikes. Apollo perhaps.
4 - Those available mostly over the internet.

But my question is what are you actually paying for when buying a more expensive one?
Is there a difference in ride quality or other factors?
Will the cheaper ones explode?
