I got a fabulously good deal on this used full carbon Pinarello bike. After getting it, I'm having an acute nagging feeling that this frame could be a fake. My local bike shop thinks it's dodgy too. The decals look fake. There is no serial number. No one knows the model or the age (except that it's an old frame). The guy I bought it off said his brother who's gone overseas gave him the bike. Most probably the brother bought it in Europe. I tried surfing the net but I can't find another Pinarello frame that looks like this. Can anyone help? Have I been conned?
