Replacing a 7-speed freewheel from my Schwinn Sidewinder, need help buying a new one.
So I'm at about a beginner level when it comes to fixing my mtn bike, and right now I'm in the process of changing the freewheel. I've got a 13/28T freewheel made by some obscure company. Originally and atm I'm planning on buying the Shimano 7-speed Tourney freewheel MF-HG37 (13-28T). I know this will replace my current freewheel, but I'm wondering if I can get a freewheel with more teeth, and if I can, would I need to make changes to my chain or anything? Thanks.
