Hello what can you tell me about this bike?
Hi! I have this bike and it is in great condition. The wheelset is two months old. I have thinner tires for road touring, but would also be willing to include thicker tires for riding dirt trails, if you're willing to spend $800.
This sounds like a good bike.  How often have you used it?
I've only used it 5 times. Once on a road tour across Oregon, and a few times on dirt trails in my hometown. How much are you looking to pay for this?
736
I can't go that low. Since I want 800 and you want 736, let's meet in the middle at 768. That way we both get what we want. I'll even include both sets of tires at that price. How does that sound?
If you throw in a warranty, I will meet you at 770
Ok. I can throw in a 2 year warranty for 770.
