I took my bike to the local bike shop today. It's been in really rough shape on account of my poor maintenance, which I pledge to be better about in the future.
The back wheel needs to be replaced because a bunch of those long thin wires that hold its shape have fallen off and caused the wheel's shape to warp, so it's all wobbly. Right now I don't even have it mounted on correctly, because I know it needs to be replaced. I've taken it off before to examine it.
I spoke to the guy at the bike shop and had him investigate other problems I was having and he told me I'd need a new rear derailleur (as a piece fell off that guides the chain came off, the chain has been "skipping" while riding), new chain(that it was stretched), and a new freewheel. For all of that and a new wheel, I was quoted $110 and $30 for labor. $140 total.
I wasn't prepared to spend that much today or else I would have already, so I think I'm going to try to find the parts cheaper online in the meantime and may still even bring it all in for them to fix it up for me.
Could you guys help me find the parts I need at a good price?
The tire on the existing wheel is "26 x 1.95", so I need a new wheel that supports that. I may just buy the one they sell at the bike shop. He told me it would cost $40 for that and I'm not seeing a much better deal online.
