The gears keep messing up so I need to downshift and upshift to stop the noise. I am thinking about getting this freewheel that's linked below as the OP suggested and the freewheel remover for $18.50 total. My local bike shop is charging $25+tax and $8+tax for the remover. They said they'd do it for free if I brought in just the wheel, but I'd like the chance to change it back out in case I need to return/exchange it. I worry about voiding the warranty if I return it with a different freewheel. Anyway, does anyone know if the FR-1 is compatible with the freewheel that's on the Genesis? I'd hate to buy 2 freewheel removers. I know you don't need a remover for installation so I'd get just the Genesis freewheel remover first if they were different. Thanks in advance for the answer and such a helpful forum.
