Hi. Newbie here. I just picked up a really cute Nishiski NFS Alpha - royal blue, chrome fork, chrome lettering with pink highlights . . . . Not even sure it's a classic or vintage or not. I wanted to make it a single speed as I was looking for a winter ride that was easier to clean than my Madone. But I'm not sure now. It's in great shape, but is a mishmash of parts. Looks like Shimano 600 RD, 105 crank, campy brakes, maybe Shimano RSX levers, Sun Mistral wheels with Shimano 600 hubs. Anyone know what is original and what isn't? Should I single speed it? Any information on the NFS Alpha would be greatly appreciated. Don't want to ruin it if it's an okay bike.
