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. ”

Top Criticism

+5 pts

“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.”
