...it's a tight and light bike. They have adjustable vertical drops on the rear, and sometimes the screws that hold them on the frame are seized in place and need some work. I have one, in lavender purple, and I wanted to put 700x25's on it, and in order to fit those tyres I needed to slide the drops all the way back....that's how tight the geometry is.

They got lusted after and sold to a lot of amateur racers when they were new. Good, solid, fast, steel bicycle from the golden age.

Be careful with those through the top tube cable fittings, they can break... difficult to find replacements.
