[QUOTE="greg brillus, post: 51959, member: 597"] Hi there Bill, I knew this would interest you as you have been particularly interested in this topic from the word go.....to answer your question, yes they can, only the needle roller conversion requires the bores to be opened out about 2 mm. This could be a reversible mod, but larger bronze bushes would need to be made.....frankly, once done you would not convert them back. For a road bike I think the main benefit would be to replace the eccentric bushes with sealed bearings as I have done. The eyes only need to be opened out very little, and would easily be reversible. We were able to literally hone the original holes out to suit the bearings. The stainless hat section "Hubs" if you could call them, took a little redesigning from the originals that Norman (Timetraveller) had made, as his were to suit the original bronze eccentric bushes.
