That looks like a T in the fuzzy picture of the shifter. If that is a T then it has Tiagra shifters of some vintage.

That bike in my market would be a 250.00 bike assuming everything else is in good rideable condition. But sounds like it needs new tires, so I would probably go 200.00

If you are looking to sell it you also need to know the size.

You mentioned finding it as a throw out. If someone threw it away it could need serious work.
