I am hoping one of you speed demons has an old bike lying around with shimano 600 Arabesque groupset attachments to restore my old 1980 bike as attached. I require a left hand 165mm crank and one front brake caliper or even an entire Malvern Star xx frame and arabesque cranks of any size if you are nearby . I have some other more recent Shimano 600 149- 159 calipers and arabesque levers I can swap if you are looking for those for your bike.
