    It comes with everything you need. If you have never swapped a crankset take it toyour local bike shop and have them do it. It will run about $60 or so and they can adjust your derailleurs too. It is pretty complicated if you have never done it.

    That suntour stuff is really heavy and you will drop a lot of weight too!
