I have a 2012 Diamondback Overdrive 29er:
Diamondback Bicycles - 2012 Overdrive

I have been riding it for a few months now. Last time out it sounded like the BB was starting to squeal. My question is, how do I know what BB to replace it with? Is there a certain type I need to use? I looked up the specs on the bike and all it said for BB was "Sealed Cartridge"

I am a newb at all this so any help would be great!

Thanks!

Bottom Bracket Size Database

Most likely you want a square taper bottom bracket.
Remove yours and have a look. You also need to measure it so you can buy on the correct length.

You need special tools to do this job. It may be cheaper to get a LBS to do the job. Sealed bottom brackets usually last very well. It may well be something else making the noise.

Thanks man. I am pretty sure it's the bb. It has been creaking and has now started squeaking. I just ordered a shimano un55 69x113 square taper. Getting the tools to do it, I would rather do it myself and learn instead of leaving the bike at the lbs for 10+ days and saving a buck or two.
