Patrick, Your attached photo (must be from Flickr?) is a pic of my 1980ish Colnago super. I think the chain rest idea is super slick, and works very well. The rear end is spaced at 126mm, and I'm using a regular 5 cog 14-24 Regina Oro freewheel. I know someone who is using an "ultra 6" freewheel in a similar era Gios - it apparently works fine. My Colnago come with the dropouts already tapped for the PC, I just chased the threads. I've seen a 1978 Colnago Super with the same dropout casting, but the holes were not yet drilled and tapped.
You may be interested to know that Campagnolo also made a single bolt version with works with any long horizontal dropout. I put one of those on my 1974 Bill Davidson, and it also works great. I'll try to attach a pic. Here's the link, just in case: http://www.flickr.com/photos/39151498@N07/8197764689/in/set-72157625243085418/ Cheers, Alex -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
