Hey there guys and girls,
I am upgrading the parts on this newly purchased bicycle, and everything was fine until I walked into a bike shop and mentioned that I was buying parts online. They said something about people buying parts that don't fit their bicycle and having a tough time returning them to get the right parts. But I figured it shouldn't be so hard to choose the right parts.

This is the questions I have,
does anyone know what kind of crank my '85 Fuji Sagres uses?
Maybe provide a way I can search them.

Thanks everyone!
