I have a Dawes Stratos in 531 tubing that I'm about to restore, there are no dents etc but the paint is tired. Groupset is Shimano 600 and will be completely renovated. If you'd like to see the quality of my projects please look here:
The Dawes will be around £350 delivered, and that will be like a new bike.

PS Any Pinarello I've seen under 400 needs mucho work!
