Been a while. Got some issues with my bottom bracket and such.

Well folks, it's been a while since I been biking. I decided to take the bike out again and now I'm addicted all over again. My ride isn't anything special. It's a 2004 Giant Boulder SE. Real solid bike, though. I've had zero issues with it until now.

I had a nasty wipe out the other day which resulted in a lot of cool scars for both me and the Giant. I noticed afterwards that my bottom bracket seemed to be loose. However, I remember it having a weird, but very light, grinding feeling before the wreck.

I just went to a bike shop to talk to the guys, and they said for 60 bucks they can replace it for me. That covers labor and the cost of the part. I was considering on doing it myself, except for the fact that I have no bike tools whatsoever and I'm on an unusually limited budget. (Just graduated, no job yet, etc)

The other thing is, my rear wheel (hub) seemed to be bent a bit. I put the bike upside down and pedaled it real hard by hand. I saw the rear of the bike moved a good bit, and after closer inspection it looked like the actual hub itself is a bit bent.

So, my questions are simply this.

Is it worth it to spend 60 bucks and fix the bottom bracket on my bike?
And how much would I expect to spend for a decent, but relatively cheap pair of wheels? Could I get them for 100 bucks?

Other than this, my bike is unusually solid, and I can't justify spending more money on a bike when this one does justice.

Also - is there any harm in continuing to ride the bike with the bottom bracket wearing out? Because I do plan to fix it, but I want to keep riding, yet I won't have money for another month. I'm thinking that the part that's going to wear out if I keep riding is the one that I'll be replacing anyway. So is there any harm in continuing to ride until I get it fixed?

You should be able to get a pair of wheels around $ 120 . More you ride more damage you will do to your bike . What kind of bb you have ? since you don"t have the needed tools for the job yes i would let the shop do it . Because the tools needed can cost up to $50 and that not parts.

That bike should have a cartridge style BB, so you won't really do any additional damage unless you get really stupid, like riding it with the mounting cups loose or similar.\Make sure it's th cartridge though and not the crank!

Although not aesthetically pleasing, it sounds like you only need the rear wheel.

As far as tools go, if you have other tools, you might be able to get by.
I recently installed a cartridge into my beater by using a large, curved jaw Vise Grips and a bit of caution. Not recommended, but it worked. I did have to buy a crank puller though for about $20. You might have the self extracting type cranks though?
Your bike is supposed to have Suntour XR-120 cranks. maybe someone will know?

But the thing is, if I have intention to eventually replace the bottom bracket, what damage could I do if I continue to ride? I understand I would damage the bracket more, but if that entire assembly is going to be replace, isn't it kind of null to worry about doing more damage when you fully intend to replace it anyway?

I'm not trying to argue, but after looking at the bb and talking to the local bike shop, it almost sounds like that's a possibility - that if I were to keep riding, the only thing that would get fried is the bracket itself - which I intend to replace.

<my bottom bracket seemed to be loose.>
What is actually loose? The shaft, the bearings, the bearing cones, the crank shaft, one side, both sides,
or what?

<my rear wheel (hub) seemed to be bent a bit.>
Very unlikely. Does the wheel wobble? If it does then a) the bearings are loose, or broken, or b) the wheel rim is not straight.
Does the wheel spin freely, or not?

I really don't know, to be honest. I'm not a bike expert when it comes to internals like this. I can tinker with chains and brakes all day but this is an issue I've never come across.

Put it this way... The cranks are fine and very sold, both attached to the bottom bracket very solid. The actual bottom bracket itself, the spindel I guess... seems to be loose. If I (with a light amount of force) push back/forth on the one crank, I can feel the other crank do the same thing together. Something in that "hub" is loose. I don't have the tools to rip it apart or else I would have tried that already.

Bike shop quoted me 55 bucks to fix, which includes cost of the part. Should I just get it done? I went riding again today and even though it's not a HUGE deal, it's annoying me.
