That's a very nice bike for the money. The Chorus drivetrain alone is worth a fair amount. But how sure are you about the geometry? The 49 Diva is probably comparable to a small Felt. How does your current bike fit you? How tall are you, what's your inseam, how long are your arms? The Diva won't be a good deal for you if it doesn't fit you. Also, do you know how the Diva sustained that ding? You really have to be mindful in buying a used carbon bike that it wasn't involved in a crash or accident. Did the ebay seller happen to say why she was selling the bike?
