DO NOT JUST TIGHTEN YOUR LOOSE SPOKES! Your rim needs to be true! If u tighten only one side and wonder why your hopping up and down on your seat then look at your rim! You either need to buy the right tools to do it or just take it to a shop! It's not that easy just banging a wrench on them and tightening them till they ring! You will destroy your rim and possibly break spokes! Do not get back on here and start complaining that your dong fang is junk because you decided to listen to someone that obviously has no clue really what they are doing! When I first read about someone saying tighten your spokes I about died thinking of all the clowns gonna be mad when they can't ride!
