Are these Giant bikes fake? There's a second hand bike I'm looking at. Photos are here: Giant defy 1 2017.
The seller says it's a giant defy 1 2017, purchased last year. I noticed the stem says something like raceface which suggests to me that it's been replaced.
I found another similar looking one where the seller says it's a Giant defy 1 2016 model. Photos are at: Giant defy 1 2016
I haven't been able to find the exact same model on the giant website.
Can anyone identify  what model is this bike? Or is it a fake?
The paint scheme looks like that of the 2009 Giant Defy Advanced 1

bikepedia.com and bicylebluebook.com have lots of info on bikes by year and model.
Here's the 2010 Giant Defy 1, which again looks very similar, with a few minor differences in the paint scheme: https://www.bicyclebluebook.com/value-guide/product/19422/
