Ken this is a custom made part from my Trimble frame 393. My frame 230 hasn't got one. And it was replaced with a brake part (not by me).
I really want the correct part. Then the frame is complete and correct.
Not like me to be so anal over a vintage part. but the frame is the heart & soul of a bike (quote from that BBC2 programme with the lawyer and his expensive road) And i agree with the lawyer :shock:
