I just bought this bike, but it seems like the frame is not Bianchi, all marks and texts are stickers. Also, there are quite a few logos on the frame. Does anyone know which frame this is?

Is there a serial number on the bottom bracket? – joseph_morris Aug 12 '14 at 20:59

Initially I thought this was an Olmo but it looks like Japanese bike frame builder 3RENSHO.

You can see some on Google or here:
