Is there any reason for the rear frame and bottom bracket to be asymmetric? I just received a new non-brand carbon frame and immediately noticed that the bottom bracket looks to stick out significantly more to one side than the other, and the rear bottom forks also seem to be have slightly different dimensions - both somewhat asymmetric along the center line of the frame.

Is there any reason for a frame to be designed like this? Does it have something to do with it being a disc brake compatible frame? Or is this more likely a manufacturing / design problem?

Here are some images:
 


Thanks! I really appreciate any help + advice.
The bottom bracket shell does not really stick out more on the drive side, it's symmetrical around the center line of the frame. The non drive side bottom bracket shell and chainstay are just more built up.

On reason is providing clearance for the chainrings on the drive side.
