Can anyone identify which Specialized Diverge model this is? It was built in 2017
That's a 2016 bike I think. The 2017 models did not have the kink in the seat stays.

I'm guessing it's above the 'Sport' Level (equipped with Sora), and below the 'Comp' (105).

I'd ask the seller if they bought it new and if so if they have a receipt.
