I've put a few hundred miles on my Sputnik and it's been complete butter, except for a kinda noisy/vibrating chainline.

The chainring looks like a piece of ****, like it's just stamped out steel. They really went cheap on the gearing! I like my ratio 46/16.

I've been hearing good things about the surly cogs. Are they all chrome in color? I'd prefer to keep it black.

How do I know what size chain I have?
