That Cannondale has a better and more expensive groupset. Both frames are alloy. I’d go with the Cannondale. What is much more important here is the sizing difference. One is a small, and the other is a 56cm which is a medium. Don’t buy a bike that won’t fit you. Research sizing on the internet.

I would skip the Cannondale because it is an early disc brake bike using post mount. I would rather have a really good rim brake bike or a fully modern flat mount disc brake with thru axles.

Best Praise

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.
