Local Bike Shope (ATA in cambridge) told me I need a new hub, they want 65 for a flip flop hub plus 70 for a new wheel which they say I need. I asked about using my wheel and it will be an addition 35 to use my own wheel... At the end they offered for 275 +tax to set me up with a flip flop hub BOTH wheels and tires. with tax that's gonna be like 300 for wheels/tire/flip flop... I REALLY don't have that kinda cash right now, anyone have any advice, I'm I getting screwed by these dudes?
