Thought I'd pop this here as I've no immediate plans to build it up. Picked this up from a wheeler dealer in leeds via eBay. Advertised as a barron cinelli 653 road bike it had the tell tale signs of being a raleigh sb at first sight. Having never seen a sb in 653 I thought there was a chance it could be 753 so took a chance on it. Stripped it down and fork weighs 633g and frame 2kg with bb and headset in place. So most likely 753r from measurements of the tubing. As it dates to 88-89 I'd like to repaint in team banana colours and use ultegra 6400 with possibly a 10 speed rear wheel (it's 130 spaced) and dura ace dt shifters.
