Rebuild now in full swing. Final polish to each item before it goes on. Nee do purchase new brake and gear cables and bar tape to finish off. Hoping that the refurbished Simplex S100 will behave and I can set up efficiently. I have an all aluminium unit ( think it is a 610 but not sure) which I can fit if the original is a problem. I know Simplex can prove to be a bit tricky.
