It worked out well, although for aesthetics I recommend it for an inner ring, where the spider will hide the five 1 mm gaps. The nice thing about this treatment is that it still leaves the ring usable for a 130mm spider.

Mine came with the usual 52-42, but I wanted a 44, to provide a better 1.5-step with my freewheel. It is very easy to do, using the countersink as a guide.

I have since accumulated several genuine 128mm rings on eBay, so my current 47-38 or 46-38 setup uses the "real deal," no mods necessary. (47-38 works great with 14-16-18-21-24 as a 10 percent lower variation on the classic 52-42/14-24; 46-38 is better if you run a tighter block in back, such as the 13-15-17-19-22-25 I am currently cobbling together from two Regina Americas.) This will give me a perfectly adequate (for me) 96 gear-inch top end, just like the 50/14 on my Binachi, and a low of 41,and still work well with my Campag. 980. Watch for Nervar Star rings -- they do occasionally still appear on eBay. Also, let me know what size(s) you want, in case I decide any of mine are surplus. (My 38 is a keeper, though!)
