Bottom Bracket Clicking; Chainring Wobbling
Okay. I have a 26" NEXT Shocker mountain bike, and it's about two years old (bought December 28, 2006). This has been going on for a year now, off and on, but now it's happening almost nonstop as opposed to just when I pedal hard. And, it's louder. So I'm a bit worried, considering a trip I plan on taking.
When the right pedal goes down, there's a loud click. The chainring wobbles a bit as well, but it's not touching anything when it does so. When I got home to take a look at it, it seems there is no damage. It seems to just be loose, for I can wiggle the entire thing freely in the bottom bracket case.
I checked various sources on the Internet, and it says that this is a very normal thing. But I can't seem to find any instructions on how to tighten it up. Moreover, I don't think I have the tools to get into it.
So, my questions are:
-How do I adjust or tighten the bottom bracket properly?
-Is there a cause for going to the LBS instead, or is this something I can handle myself cheaply?
I can't find the name of the manufacturer of the BB, so... Here is a picture. If it isn't efficient, please tell me and I can try again:
EDIT: Actually, I think I just found the problem. It appears the entire bottom bracket has been bent.
