Bottom Bracket 101
 

For anyone who doesn't understand what a bottom bracket is, or how it works, Bikerumor.com did a nice breakdown. Some of you may be interested in reading this.

good article, thanks

Yes, a good article indeed.

Thanks!

Looking forward to reading it. Thanks for posting.

So that's what all the hubbub is about.

No, the BB--not the hub. Bub.

Every
word
is
on
a
new
line
when
I
open
the
page

Pretty much unreadable in IE6 at work.

Hubs are for wheels, bottom brackets are for cranks! :D

That's a pretty limited overview of bottom bracket technology.

I think that's why it received the "101" designation. I thought it served that role rather well.

why does it matter that there are lots of systems. as long as you pick one and stick with it, what's the big deal?

Wow, another bf thread gone to ****. Thank you, highschool dropouts!

you should know better. i tried a serious thread yesterday. It sank wihtout a trace with all hands on board.

decent writeup, though I skipped to the newer stuff. same standards as wheels NONE...lol

You just got to worry about what YOUR set-up is, cause it wont work with another PITA!

You're surprised?
Any useful information posted on the road forum quickly falls into oblivion.

thanks for sharing!

btw: post this on another thread and you'd get a different response. all in all, I find it interesting to get many viewpoints with certain "questions" Sometimes I find myself posting in counter-intuitive forums knowing that the viewers might be more informative or responsive because it has more viewers, etc

- road riding = high performance experts (cool)
- commuters = inventive and a bit whack! (fun)
- mechanics = incredibly knowledgeable - amazing knowledge base here (a lifesaver)
- 50+ = what we will be like if we stay healthy and keep riding. the wisest of the wise (comforting)
- classic and vintage = they won't ridicule you for having an old bike and they are very accepting of whatever you ride. amazing what restorations this group gets into - again a huge knowledge base (like the 50+ crowd meets mechanic-ville)
- electronics and gadgets = great place to find ways to spend your money (where I learned about MagicShine)

- I guess I can keep going on this tangent but since I have ADD from chewing windowsills as a kid I'm bored now

How long do BB's typically last? I've got over 20K and mine still seems to be OK. Last spring it (or something) started making a clicking noise, but it went away.

I think you got your moneys worth huh? the noise went away? seriously? why not have someone open it up and service it - who knows what they might find

would it be accurate to say that square taper will disappear eventually and the most common will be external bearings?

I'm wondering if i should stock up on square BB for my older bike.

I've got a nice SKF BAS-600 square taper BB on the shelf awaiting my next recumbent bike. Snagged for $50 on Ebay, SKF claims 10,000 mile service intervals on it.
