Just picked up a 1983 Nishiki Olympic with Tange 5 tubes for 20$ and i figured it would be a decent option for a fixed build. This is most likely going to be my winter beater so I'll be doing this on a reasonable budget. I had a few questions as I'm not familiar with some of the components. The bike came with Sugino VT cranks, are they the bottom of the barrel or where do they stand in the Sugino product line quality wise. Also is it advised to replace the BB and headset because the parts are over 25 years old? Comments are always welcome. Here's a few pics of the current status
