Making New Components Work as Vintage

I really like vintage Campy components. I scour the ebay and other sources (craigslist is a non-sequitur in this area). Saying that, there are some components that are either too scarce and/or expensive to use on a regular basis. One of these are chainrings for my Nuovo Gran Sport (NGS) crankset; NGS chainrings in 144BCD often cost more than Nuovo Record. While I have some OEM chainrings,



I ride the bike a lot and don't want to wear them out. Origin8 have some since retro rings that come in 42T and 52T (they have a much larger selection of retro track (1/8) rings, but only these two in 3/32). I like the dull finish that is similar to NGS, the 42T is a standard 10 hole, but the 52T is also a 10 hole, which looks awful.


So I bought a set and went to work with a Dremel tool to turn the 10 hole into a 5 hole. Below is my new set with a Origin8 52T converted to a 5 hole.
