Hey guys I was on a ride yesterday and started to get a creaking/crackling noise (like a barring being eaten).
So I am assuming that somehow in less than 3000 miles I destroyed a BB. I was wondering if anyone had any advice on what I should replace it with. That will work with the other 2012 Shimano Tiagra parts. I don't really care about super light components, but I am looking for long lasting parts for long distance riding (80+ miles a day).

I was looking at the BB and it says on it is "BC1.37 x 24 road JE" I don't know exactly which BB this is but if it last less than 3000 miles than I don't want it.

Thanks for any advice

New bike, could it still be under warranty?

It should be I got it in April. But it will cost about as much in gas to drive to the shop I got it from and back as it would to buy a Dura-Ace BB off of Amazon, and there's no way I'm taking my bike to my local trek dealer.... The guy doesn't like steel bikes ( the reason I didn't buy a bike from him ). I guess I could try to give Raleigh a call.

Okay so I was thinking of getting this bottom bracket https://www.nashbar.com/bikes/Produc...0052_194629_-1
does anyone see anything wrong with that / can think of anything better before I order it?

Check you've actually destroyed the current BB? Does it have any play in it, or feel stiff?

I'd assume the BB in your link would be compatible, although it may not last much longer than the current one if the BB shell on your frame hasn't been faced properly. External-bearing BBs are far less tolerant of misalignment of the shell faces than the conventional internal ones. I'd think a bike that came with an external BB as standard would already be prepped and faced for one, but destroying a BB in 3 months sounds a bit odd...

If it hasn't been faced properly, most bike shops should be able to do it these days.

The frame seems like it was face properly from the factory, Also the unit doesn't have any real play in it, it's just a grinding noise with added resistance and it feels notchy where are before it felt smooth when the crank was spun. I have cleaned the area and looked into what I can but I'm not use to this style of BB as it's the first external bearing unit I ever had.

I have ridden this through a few showers ( well heavy down pours ) it can't be avoided in FL during the summer unless I want to spend my summer on the trainer. So that might have something to do with it, The last one was pretty nasty.
