Default Re: 3/4" o.d. tubing

The problem is that all standard seat posts are larger than 3/4". The converters won't work. The inside diameter of my seat riser is almost dead on 20 mm so I would be looking for a 19mm post. Believe me I have been checking Ebay and various online vintage bike shops. Nobody seems to have such a thing. I am guessing at this point it must have been an odd design that Murray used for 1 or 2 years and nobody has it. So I am looking for stock material to replace it with.
If it can't be broken I'll find a way!


I'm not lost, I'm exploring!
