I am new to all this and it is quite confusing. Looking at eBay, an Italian Sprint bottom bracket sold for $18 in November...before I knew I needed one. I just added it to my followed searches. Maybe I'll get lucky in the coming months. I have a Campy Victory group with English bottom bracket, a Sprint group with no bottom bracket and a 600 group with a UN55 that should work (English). I was planning on putting the Victory group on a Kono Allez (English threaded and already has a Campy headset installed) and the Sprint group on a BMZ frame (Italian thread). Maybe I should swap those and put the 600 on the Allez and find an Italian bottom bracket for the Victory group for the BMZ. That way, I match Japanese and Italian frames and groups. That leaves the Sprint group for another build (I have two 600 bikes and like the look of Sprint, which is why I wanted to use it). I would still be looking for a 109 Italian bottom bracket as it looks like Victory and Sprint would have the same spindle and possibly the same taper. Maybe that's the way I'll go and keep an eye out for a bottom bracket for either Victory or Sprint. Or, find another English threaded frame for the Victory group.
