Question about selling

It looks like a fine bike, but there are some factors that narrow your audience here: the age (10+ years), the large frame, its long low cockpit geometry, the individualistic triathlon setup, the mixed Campagnolo and Shimano drivetrain, and the need of a bit of light maintenance. For maximum profit, it might make sense to part it out. It's possible that's what your buyer will do anyway.

Replace, or have someone replace that kinked rear shift cable and housing. It's an open invitation for bargaining down the price. When you list it, post a clear full profile photo of the right-hand (drive) side so your customers can eyeball its size and proportions and the drivetrain.

I'd list it locally for $1100. Don't mention "or best offer," you'll get those anyway. In the ad, stress positives--it's in excellent condition, the steerer hasn't been cut, and the Mavic wheels are 11-speed compatible. I don't know whether he's got a Campagnolo or Shimano cassette on there, but if it's the wrong one for your buyer, the replacement is only $100. And be prepared to negotiate. I'd probably let it go for $900 in a snap, but for anything lower than that, say you'll get back to them.

Your ideal customer will be a young triathlete who is tall, doesn't have a lot to spend but wants something special, and doesn't mind if it's a little odd if he can make it go fast. Or, a tall road rider who doesn't mind putting in some parts and sweat equity to make it his.
