You will get more interest on Facebook etc.
I sold a Kinesis Ti frame, a complete Van Nic Chinook, and a complete Kinesis CX V6 fairly quickly on Facebook (Yorkshire Cycling Sales)
The Van Nic I sold wasn't as old as yours, I sold it for a lot less than a £1000 but that was last year, bikes are seling well at the moment but £1200 might be a bit high.
