Cup and Cone versus Cartridge

When you dissasemble the crank, look at the bearings, if you can see
ball bearings...

If you can't see bearings, but a sealed cartridge looking thing
instead...

If you can't take apart the crank, find someone else to work on your
bike.

Look at the bottom bracket on the non-drive side. If there's a ring with
about 8 radial notches (not 20 little ones) then you have a cup and cone
bottom bracket. If you see 20 little ones, you have a cartridge BB.

This doesn't apply to Truvativ bottom brackets, as they look like a
cup-and-cone BB.

All non-square-taper bottom brackets, one-piece cranks, and ones that use
cotter pins, are cup-and-cone.

See a shaft,ring,or free floating ball bearings it cup and
cone. See any- thing other it sealed. Both can be serviced if you
know what your doing.

A cartridge is removed using a socket-driven splined tool
like the Park BBT-2. A cup and cone unit is disassembled
using a Hook Spanner (aka Lockring Wrench).

Picture tells a thousand words, then sheldon adds a few
more to make the picture clearer:

Jeeze, you got all these serious responses (and good ones too). I
thought I should chime in with the traditional smart ass a.m-b response.
Here goes:
If you do a foot deep stream crossing every ride 100 times a year and
don't do any maintenance, the cup and cone BB is the one that sounds
like you have pea gravel and cat litter for bearings. OCYMMV

Well done. I tried to figure out a way to describe it this morning but
couldn't do it properly. It was before my coffee.

Also: how old is your bike and what parts are on it? If it's pretty
new, chances are it's cartridge.

Brought in 1999. Its a GT Outpost Trail bike with Shimano parts. It has a
Uniglide chain and a Acera X rear derailluer. Not sure about the rest.

Based on the year and assuming that the bb is Shimano, chances are
it's sealed. I don't work in a shop or anything, but I personally
haven't seen a Shimano cup/cone bb since before, what, 1990?
