Hoping that someone can help. I am looking for a TA (Pro Vis?) tandem triple crankset from late on-topic period in good to very good condition at minimum. Chainrings not important but need arms and spiders 170 to 172.5 considered, prefer English threaded. Respond off list with condition / price. T.I.A.
