Preferably Precisa straight version, but would consider anything bigger than a 215mm steerer (threaded), one inch. Would also consider 235mm+ carbon one inch Colnago.
Chrome finish preferred but would consider painted.
I have these. Unused, unscathed, uncut. 300mm/30cm steerer you can get threaded yourself. Bought them for a build that I ended up doing with a curved fork.
