There is a thread here somewhere on this but "Custom Built" means different things to different people. while I have a house full of bikes that may be considered custom built I never had a frame custom built for me although I did get to pick the color of decals on one bike and wether one got painted or left all natural.

I find it odd that while the seller calles it possibly a one of kind one owner bike, the listing reads more like he just got it somewhere and is selling it. he does say I did, or I only got caught in the rain once, or anything like that.

Pinarello decals are notorious for coming off I wonder if at some point the owner just took them off and put this Gios inspired style decals on.
