Of these the the first one. The Giant Contend. You’re definitely not gonna be a size 56 or 58. Price seems within reason. Maybe you could get if for a couple hundred less. Or maybe you could flip it for a profit with a little patience. Totally depends on your market and condition.

Go for the felt, yes it's worth 900 imo. The giant is quite old and the bar tape needs doing. 8 speed 105 was a while ago, the technology is a lot better now.

My god, a lot of low ballers here. Someone said that’s a 1000$ bike. Hahahahahaha. Anyway, that’s close to 2k$ value. Regardless if it’s “old”, it’s still a modern frame, S-Works at that and it has Di2.

This is a bike from the mid late 2000s, hard to say exactly which year. Even as an S-Works, this is an old ass triathlon bike and is worth nowhere near $1200. Seller must have a great dealer. I concur with the other poster, around $300 is probably reasonable.
