I am going with the advice of East Hill and seeking the wisdom from the C&Vers. I have a Bianchi Limited steel frame with serial number JS11179. Of the original components I have a Suntor Cyclone M-II front derailer.

My questions is that I notice a slight dent in the chainstay by the cranks. I am told it is possible the frame was designed this way and it is not an accident. I'm curious if anyone here knows if this dent in the following pictures is intentional or not. If you need more details on the frame I'd be happy to answer them.

Thanks for any help.
