Does it matter what kind of chain I have on my fixie? I have an old index chain and was wondering if i can just use that? If its not a good idea, what should i be looking for, bmx?
The wheels that I have coming inthe mail are spaced at 120mm however my frame is 126mm. Can I still use the wheels as is or should I add spacers?
What is the best location for the chainring? inner or outer mounting?
