Ava alloy stem and bars diameter
I have a 1971 px10 in the mail. Id like to replace the Ava stem. It should be a 22.0 diameter stem but I'm wondering what the clamp size would be if I want to reuse the original Ava bars. 25.0? 25.4?
Also, some of the stems I am looking at are open at the back (you can see the quill bolt). Is this normal? Seems like a great place for water to get into the steerer.
