None of the above. An Italian proddy bike

Sorry I couldn't resist but this question comes up on a daily and most riders say X12, other say X8, and a few say X7. These China bikes are not all created equal so just because Joes down the street is faster then Johns does not mean yours being the same will be just as fast. He may have got a "oops" bike meaning oops that one was actually put together correctly. What you put in is ultimately what you will get back in return from the bike. Which ever you decide on enjoy and be safe.
