To be clear, my argument is not that BD sells inferior quality bikes. For the price, the quality of the frames and components is quite good and I wouldn't necessarily avoid buying them. However, whereas most brands put some thought into the design and componentry of the bike before releasing it, BD tends to just throw random ideas out there without thinking much about it, other than how well it might sell. Thats why you end up with 10,000 different models based on the same 2 or 3 frames. Its also why they don't care about the little details, such as if the fork rake matches the frame geometry correctly, or if a frameset with fender eyelets actually has clearance for fenders. This is the number one reason why, despite being tempted to buy a bike from BD, I never actually have. There is something that is just always off.

Their road and MTB offerings are not so misfit, probably because with those bikes its easiest to stick to the standard formula, with a series of bikes based around a few different style framesets that are priced according to a standard component hierachy (e.g. tiagra, 105, ultegra, duraace). ALso you aren't going to find people in the roadie or MTB crowds that are willing to buy mismatched parts, or pointless dead weight like double top tubes, or unpainted frames.
